It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

In Release 18 (Rel 18) SBFD communication topic, UL subband is introduced. The base station configures UL subband on the downlink (DL) time unit or flexible time unit, and the terminal can transmit uplink information on the UL subband, as shown in Figure 1. The time and frequency domain resources occupied by the UL subband can be determined by explicit or implicit configuration, which is not limited in the present disclosure.

Among them, the time unit can be a time slot, an orthogonal frequency division multiplexing (OFDM) symbol, a subframe, a frame, etc., which is not limited in the present disclosure.

For frequency hopping transmission, frequency hopping transmission within a time unit and across time units is supported. When the time unit is in units of slot or OFDM symbol, the frequency hopping transmission includes intra-slot frequency hopping transmission and inter-slot frequency hopping transmission.

When the terminal performs intra-slot frequency hopping transmission of uplink information, the terminal transmits the uplink information in units of OFDM symbols within one slot. The same uplink information can be divided into two parts for transmission, and the two parts occupy different frequency domain resources respectively.

In the present disclosure, uplink information includes but is not limited to at least one of the following: Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Sounding Reference Signal (SRS), etc.

Among them, the PUSCH may be the PUSCH scheduled by a random access response (RAR) message, or the PUSCH may be the PUSCH indicated by message 3 (Msg3), or the PUSCH may be the PUSCH indicated by downlink control information (DCI), media access control element (MAC CE), radio resource control (RRC) message and other indication information, and the present disclosure does not limit this.

The base station can indicate the frequency domain resources occupied by the terminal when transmitting PUSCH through frequency domain resource allocation (Frequency Domain Resource Allocation, FDRA) indication information. Taking the PUSCH scheduled by the RAR message as an example, the base station can indicate in the frequency domain resource allocation (Frequency Domain Resource Allocation, FDRA) field of the RAR message, including:

exist Or in shared spectrum channel access operation When, define

Specifically, the corresponding FDRA field can be parsed based on the lowest N bits of the FDRA field, wherein, if the PUSCH enables frequency hopping, the first N _UL,hop bits of the FDRA field except the lowest N bits are used to indicate the corresponding frequency hopping offset (offset);

Otherwise, the first N _UL,hop bits of the FDRA field indicate the corresponding frequency hopping offset, and when parsing, based on N bits, considering that in the non-shared spectrum scenario, N is greater than 14 bits, the terminal is based on the indication information and based on the insertion after N _UL,hop bits. It is worth noting that the preset bit is a bit added by the terminal when parsing the indication information, and no corresponding change is made to the specific indication bit.

in, Equal to the number of resource blocks (RBs) included in the initial uplink (UL) BWP. The initial uplink BWP may be a BWP frequency domain resource configured by the base station for the terminal and used when performing uplink transmission for the first time, or may be configured during the random access process, which is not limited in the present disclosure.

As described above, for the PUSCH scheduled by the RAR message or the PUSCH used to perform Msg 3 retransmission, the frequency domain resources occupied by it can be indicated by the PUSCH FDRA field of the RAR message (the FDRA field constantly occupies 14 bits or occupies 12 bits under shared spectrum), where the bit value of N _{UL, hop} is used to indicate the frequency hopping offset, and the specific corresponding relationship is shown in Table 1 below:

Table 1

For PUSCH resource allocation type 1, frequency domain resources can be indicated based on a resource indication value (RIV). The RIV is associated with the starting RB index value Rb _start and the number of continuous RBs L _RBs of the frequency domain resources. The determination method is as follows:

if So

otherwise

Among them, L _RBs ≥1 and does not exceed

Among them, Rb _start is the RB interval number of the starting RB of the frequency domain resource compared to the BWP starting RB, and L _RBs is the number of RBs occupied by the frequency domain resource. For example, as shown in Figure 2, the starting RB index value Rb _start in the frequency domain resource scheduled by the base station is 7, and the number of continuous RBs L _RBs is 9. According to This formula can calculate a unique RIV.

Currently, PUSCH is only transmitted in time units configured as UL. In the SBFD scenario, in the SBFD time unit, the terminal can be configured to transmit PUSCH on the UL subband.

The SBFD time unit refers to a downlink time unit configured with UL subband and/or DL subband, or the SBFD time unit is a flexible time unit configured with UL subband and/or DL subband, as shown in Figure 1. The time unit can be in units of slot, symbol, frame, or subframe, which is not limited in the present disclosure.

The UL subband referred to in the solution of the present invention refers to the frequency domain resources where the UL subband configured by the base station overlaps with the uplink BWP, and the terminal can be configured to perform uplink transmission on the UL subband. In the SBFD time unit, the frequency domain resource range occupied by the UL subband is less than or equal to the frequency domain resource range occupied by the UL BWP. If the frequency domain resources occupied by the PUSCH frequency hopping transmission are determined based on the frequency domain resource range occupied by the uplink BWP in the SBFD time unit, it is obviously inaccurate and easily causes inconsistent understanding between the terminal and the base station.

In order to solve the above technical problems, the present disclosure provides the following resource determination, resource indication method and device, and storage medium, which can determine the frequency domain resources occupied by uplink information frequency hopping transmission in the SBFD scenario, ensure that the terminal and the base station have a consistent understanding of the frequency domain resources, and improve the feasibility and reliability of communication in the SBFD scenario.

The following first introduces the resource determination method provided by the present disclosure from the terminal side.

The present disclosure provides a resource determination method, as shown in FIG3 , which is a flow chart of a resource determination method according to an embodiment, which can be executed by a terminal. The method may include the following steps:

In step 301, frequency domain resource indication information sent by a base station is received.

In an embodiment of the present disclosure, the terminal may receive a first message including an FDRA field sent by a base station, and the terminal determines the frequency domain resource indication information based on the FDRA field. The first message may be a RAR message, Msg3, DCI, MAC CE or RRC message, etc., which is not limited in the present disclosure.

In step 302, when frequency hopping transmission is performed on uplink information across time units, the frequency domain resources occupied when transmitting the uplink information are determined based on the frequency domain resource indication information.

In the embodiments of the present disclosure, uplink information includes but is not limited to PUSCH, PUCCH, SRS, etc.

Wherein, when performing frequency hopping transmission on the uplink information across time units, the terminal may determine the frequency domain resources occupied when transmitting the uplink information based on the frequency domain resource indication information.

In a possible implementation manner, the frequency domain resource may be a first frequency domain resource, and the first frequency domain resource is located within a frequency domain resource range occupied by an uplink BWP.

In another possible implementation, the frequency domain resource may be a second frequency domain resource, and the second frequency domain resource is located within the frequency domain resource range occupied by the first subband. The first subband is a UL subband, and when the terminal is configured to perform uplink transmission on the first subband, the terminal needs to perform uplink transmission based on the second frequency domain resource. Exemplarily, the first subband is located on a SBFD time unit in the time domain, wherein the SBFD time unit is in units of slots, symbols, frames, subframes, etc., which are not limited in the present disclosure.

When the terminal performs frequency hopping transmission on the uplink information, it may be transmitted on the first type of time unit and the second type of time unit at the same time. At this time, it is necessary to determine the frequency domain resources specifically used by the uplink information on different types of time units. The following describes the methods for determining the corresponding frequency domain resources based on different time unit types:

In a possible implementation manner, in response to determining that it is located in a first type of time unit, the terminal determines that the frequency domain resource occupied when transmitting the PUSCH is the first frequency domain resource.

In the disclosed embodiment, the first type of time unit may be a non-SBFD time unit, that is, the first type of time unit is a time unit that does not belong to the SBFD type. Exemplarily, the first type of time unit may be a UL time unit. In the first type of time unit, the terminal transmits uplink data within the UL BWP range based on scheduling, and the base station does not configure the UL subband and/or DL subband in the time unit. Here, the UL subband refers to the subband in which the terminal is configured to perform uplink transmission, and the DL subband refers to the subband in which the terminal is configured to perform downlink reception.

Exemplarily, the first type of time unit may be an uplink time unit in which a UL subband and/or a DL subband is not configured, or the first type of time unit may be a flexible time unit in which a UL subband and/or a DL subband is not configured.

In the non-SBFD time unit, the terminal may determine that when frequency hopping transmission is performed on the uplink information across time units, the frequency domain resource occupied when transmitting the uplink information is the first frequency domain resource.

In another possible implementation, in response to determining that the terminal is located on a second type of time unit, the terminal may determine that the frequency domain resource occupied when transmitting the uplink information is the second frequency domain resource. The second type of time unit is a SBFD time unit, for example, the second type of time unit may be a time unit configured with a UL subband and/or a DL subband.

Exemplarily, the second type of time unit may be a downlink time unit configured with a first subband (i.e., UL subband) and/or DL subband, or may be a flexible time unit configured with a first subband (i.e., UL subband) and/or DL subband. In the SBFD time unit, the terminal may determine that when frequency hopping transmission is performed on uplink information across time units, the frequency domain resource occupied when transmitting the uplink information is the above-mentioned second frequency domain resource. The second frequency domain resource is within the UL subband range.

In one possible implementation, the frequency domain resource indication information sent by the base station can be used to directly indicate the first frequency domain resource, that is, the base station indicates the first frequency domain resource based on the frequency domain resource range occupied by the uplink BWP. Accordingly, if the terminal is in a first type of time unit, the terminal directly determines the first frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information. If the terminal is in a second type of time unit, the terminal cannot directly determine the second frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information. The present disclosure also provides a specific method for determining the second frequency domain resource at this time, which will be introduced in subsequent embodiments and will not be introduced here for the time being.

In another possible implementation, the frequency domain resource indication information sent by the base station can be used to directly indicate the second frequency domain resource, that is, the base station indicates the second frequency domain resource based on the frequency domain resource range occupied by the first subband. Accordingly, if the terminal is in the second type of time unit, the terminal directly determines the second frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information. If the terminal is in the first type of time unit, the terminal cannot directly determine the first frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information. The present disclosure also provides a specific method for the terminal to determine the first frequency domain resource at this time, which will also be introduced in subsequent embodiments and will not be introduced here for the time being.

In the above embodiment, in the SBFD scenario, the frequency domain resources occupied by uplink information transmitted by frequency hopping across time units can be determined to ensure that the terminal and the base station have consistent understanding of the frequency domain resources, thereby improving the feasibility and reliability of communication in the SBFD scenario.

In some optional embodiments, the frequency domain resource indication information is used to indicate the first frequency domain resource.

In a possible implementation manner, the frequency domain resource indication information is used to indicate at least one of the following: first resource indication information; first frequency hopping indication information.

The first resource indication information is used to indicate the first frequency domain resource occupied by the uplink information in the first time unit. It should be noted that the first time unit is a first type of time unit, that is, a non-SBFD time unit.

The first frequency hopping indication information is used to indicate the first frequency domain offset of a hop on a first type of time unit relative to a previous hop on the first type of time unit when transmitting the uplink information. For example, slot#0 and slot#1 are time units of the first type, and slot#2 and slot#3 are time units of the second type. The terminal frequency hops on the above four slots to transmit uplink information, and the first offset is the frequency domain offset of a hop of the terminal on slot#1 relative to a hop of the terminal on slot#0.

It should be noted that the number of bits occupied by the first frequency hopping indication information in the frequency domain resource indication information is n, and n is determined based on the number of RBs occupied by the uplink BWP.

The terminal can determine n based on Table 1, for example, the number of RBs occupied by the uplink BWP is greater than or equal to 50, then the value of n is 2, that is, the first frequency hopping indication information occupies 2 bits in the frequency domain resource indication information. If n is less than 50, the value of n is 1, and the first frequency hopping indication information occupies 1 bit in the frequency domain resource indication information. In one example, the first time unit may include but is not limited to at least one of the following time units: a time unit where the index value of the uplink information is an even number; a time unit where the first hop of the uplink information is located.

In one example, the first resource indication information may be used to indicate at least one of the following: a first starting RB number; a first RB number.

The first starting RB number is the number of RBs between the starting RB of the first frequency domain resource and the starting RB of the uplink BWP.

The first number of RBs is the number of RBs included in the first frequency domain resources, that is, the number of RBs occupied by uplink information.

It should be noted that the first resource indication information can be used to indicate the first starting RB number, and the first RB number can be determined based on a protocol agreement or other predefined methods. Alternatively, the first resource indication information can be used to indicate the first RB number, and the first starting RB number can be determined based on a protocol agreement or other predefined methods. Alternatively, the first resource indication information can be used to indicate the first starting RB number and the first RB number.

Exemplarily, the first resource indication information is used to indicate uplink information, such as PUSCH in a time unit with an index value of 0, 2, 4, 6, ..., and the time unit is a first type of time unit, the frequency domain resources occupied by the PUSCH are first frequency domain resources, and/or the first resource indication information is used to indicate uplink information, such as the first frequency domain resources occupied in the time unit where the first hop of the PUSCH is located.

When the terminal is located in a first time unit, and the first time unit belongs to a first type of time unit, the terminal determines that the frequency domain resource occupied when transmitting the uplink information is the first frequency domain resource, and the manner of determining the first frequency domain resource is as follows:

The first frequency domain resources occupied by the first time unit whose first time unit index value is an even number are related to the first starting RB number and the first RB number.

The first frequency domain resources occupied by the first time unit whose first time unit index value is an odd number are related not only to the first starting RB number and the first RB number, but also to the first frequency domain offset indicated by the first frequency hopping indication information.

In this disclosure, it is assumed is the index value of the first time unit, that is is the index value of the non-SBFD slot. The terminal can use the following formula 1 to determine the index value of the starting RB for transmitting uplink information in the first time unit:

RB _start is the first starting RB number, RB _offset is the first frequency domain offset indicated by the first frequency hopping indication information, The number of RBs occupied by the uplink BWP.

Understandably, It refers to the first time unit whose index value is an even number. At this time, the index value of the start RB of the first frequency domain resource occupied by the terminal when transmitting uplink information is RB _start . It refers to the first time unit with an odd index value. At this time, the index value of the starting RB of the first frequency domain resource occupied when transmitting uplink information is

L _RB refers to the first RB number, that is, the number of RBs included in the first frequency domain resources.

The RB _start and L _RB are determined based on the frequency domain resource range occupied by the uplink BWP. Specifically, the terminal may determine the RB start and L RB based on the first resource indication information indicated by the frequency domain resource indication information sent by the base station.

The RB _offset can be determined based on Table 1. For example, the value of n has been determined before, assuming that n is 2, that is, the first frequency hopping indication information occupies 2 bits in the frequency domain resource indication information. The bit value corresponding to the first n bits in the frequency domain resource indication information is 01. Based on Table 1, it can be seen that the frequency hopping offset corresponding to the bit value "01" is The terminal determines the first frequency domain offset

In the first time unit with an even index value, the terminal occupies L _RBs starting from the RB with an index value of RB _start to transmit uplink information, and in the first time unit with an odd index value, the terminal occupies L RBs starting from the RB with an index value of Starting from the RB of , L _RBs are occupied to transmit uplink information, as shown in FIG. 4A .

When the terminal is located in a time unit of the second type, the terminal determines that the frequency domain resource occupied when transmitting the uplink information is the second frequency domain resource, wherein the second frequency domain resource can be based on the second starting RB number, the second RB number, and the second frequency domain resource. The specific determination method is as follows:

The second frequency domain resources occupied by the terminal in the second time unit with an even index value are related to the second starting RB number and the second RB number, wherein the second starting RB number is the number of RBs between the starting RB of the second frequency domain resources occupied by the uplink information in the second time unit and the starting RB of the first subband, and the second RB number is the number of RBs included in the second frequency domain resources occupied by the uplink information in the second time unit.

In one example, the second starting RB number may be equal to the first starting RB number.

In one example, the second number of RBs may be equal to the first number of RBs.

The second frequency domain resource occupied by the second time unit with an odd index value is related to the second starting RB number and the second RB number, and is also related to the second frequency domain offset indicated by the second frequency hopping indication information. The number of bits m occupied by the second frequency hopping indication information is determined based on the number of RBs occupied by the first subband.

The present disclosure provides Table 2, and the value of m can be determined based on Table 2.

Table 2

For example, the number of RBs occupied by the first subband is greater than or equal to 50, then the value of m is 2, that is, the second frequency hopping indication information should occupy 2 bits. If it is less than 50, the value of m is 1, and the second frequency hopping indication information should occupy 1 bit.

Generally, the number of RBs occupied by the first subband is less than or equal to the number of RBs occupied by the uplink BWP. Therefore, the values of m and n exist in the following cases:

In the first case, the number of RBs occupied by the first subband is equal to the number of RBs occupied by the uplink BWP, and both are less than 50, then the values of m and n are equal, both are 1.

In the second case, the number of RBs occupied by the first subband is equal to the number of RBs occupied by the uplink BWP, and both are greater than or equal to 50, then the values of m and n are equal, both are 2.

In the third case, the number of RBs occupied by the first subband is less than the number of RBs occupied by the uplink BWP, and the number of RBs occupied by the first subband is greater than or equal to 50, then the values of m and n are equal, both of which are 2.

In the fourth case, the number of RBs occupied by the first subband is less than the number of RBs occupied by the uplink BWP, and the number of RBs occupied by the uplink BWP is less than 50, then the values of m and n are equal, both 1.

In the fifth case, the number of RBs occupied by the first subband is less than the number of RBs occupied by the uplink BWP, and the number of RBs occupied by the uplink BWP is greater than or equal to 50, and the number of RBs occupied by the first subband is less than 50, then the values of m and n are not equal, the value of m is 1, and the value of n is 2.

Based on the above situation, it can be seen that m≤n.

Since the frequency domain resource indication information sent by the base station is used to indicate the first frequency domain resource, and the number of bits n occupied by the first frequency hopping indication information is greater than or equal to m, in one example, the terminal may determine the second frequency hopping indication information by the bit value corresponding to the m least significant bits in the first frequency hopping indication information. In another example, the terminal may determine the second frequency hopping indication information by the bit value corresponding to the m most significant bits in the first frequency hopping indication information.

For example, the number of bits occupied by the first frequency hopping indication information is 2, the number of bits occupied by the second frequency hopping indication information is 2, and the bit value of the first frequency hopping indication information in the frequency domain resource indication information is "10", then the terminal determines that the bit value corresponding to the second frequency hopping indication information is also "10".

For another example, the number of bits occupied by the first frequency hopping indication information is 2, the number of bits occupied by the second frequency hopping indication information is 1, and the bit value of the first frequency hopping indication information in the frequency domain resource indication information is "10", then the terminal determines that the bit value corresponding to the second frequency hopping indication information is "0" (the bit value corresponding to the m least significant bits) or "1" (the bit value corresponding to the m least significant bits).

After determining the second frequency hopping indication information, the terminal can determine the second frequency domain offset based on Table 2. For example, slot#0 and slot#1 are time units of the first type, slot#2 and slot#3 are time units of the second type, and the terminal transmits uplink information by frequency hopping on the above four slots. The second offset is the frequency domain offset of a hop of the terminal on slot#3 relative to a hop of the terminal on slot#2.

For example, if the terminal determines that the bit value corresponding to the second frequency hopping indication information is "10", it can be determined based on Table 2 that: (In the present disclosure, if the frequency domain offset is a negative value, it can be offset downward.) For another example, if The terminal determines that the bit value corresponding to the second frequency hopping indication information is "0", then based on Table 2, it can be determined that:

In this disclosure, it is assumed is the index value of the second time unit, that is is the index value of the SBFD slot. The terminal can use the following formula 2 to determine the index value of the starting RB for transmitting uplink information in the second time unit:

in, is the second starting RB number, is the second frequency domain offset indicated by the second frequency hopping indication information, is the number of RBs occupied by the first subband.

Understandably, Refers to the second time unit with an even index value. Under the condition that the second time unit belongs to the second type of time unit, for example, the SBFD time unit, the terminal determines that the index value of the starting RB of the second frequency domain resource occupied when transmitting the uplink information is It refers to the second time unit whose index value is an odd number. Under the condition that the second time unit belongs to the second type of time unit, for example, it belongs to the SBFD time unit, the index value of the starting RB of the second frequency domain resource occupied when transmitting the uplink information is determined to be

It refers to the second RB number, that is, the number of RBs included in the second frequency domain resources.

in,

in, It can be determined based on Table 2. The specific determination method has been introduced in the above embodiment and will not be repeated here.

The terminal starts at the second time unit with an even index value. RB starts and occupies RBs are used to transmit uplink information. In the second time unit with an odd index value, the index value is RB starts and occupies RBs are used to transmit uplink information, as shown in FIG4B .

In the above embodiment, the frequency domain resource indication information indicates the first frequency domain resource occupied by the uplink information during frequency hopping transmission within the range of frequency domain resources occupied by the uplink BWP. The terminal can determine the frequency domain resources occupied when the uplink information is frequency hopping transmitted across time units on different types of time units, ensuring that the terminal and the base station have a consistent understanding of the frequency domain resources, thereby improving the feasibility and reliability of communication in the SBFD scenario.

In some optional embodiments, the frequency domain resource indication information is used to indicate the second frequency domain resource.

In a possible implementation manner, the frequency domain resource indication information is used to indicate at least one of the following: third resource indication information; third frequency hopping indication information.

The third resource indication information is used to indicate the second frequency domain resource occupied by the uplink information in the second time unit. It should be noted that the second time unit is a second type of time unit, that is, a SBFD time unit.

The third frequency hopping indication information is used to indicate a third frequency domain offset of a hop on a second type of time unit relative to a previous hop on the second type of time unit when transmitting the uplink information. It should be noted that the number of bits m occupied by the third frequency hopping indication information is determined based on the number of RBs occupied by the first subband.

The terminal may determine m based on Table 2, for example, the number of RBs occupied by the first subband is greater than or equal to 50, then the value of m is 2, that is, the second frequency hopping indication information should occupy 2 bits. If it is less than 50, the value of m is 1, and the second frequency hopping indication information should occupy 1 bit.

In an example, the second time unit may include but is not limited to at least one of the following time units: a time unit where the index value of the uplink information is an even number; and a time unit where the first hop of the uplink information is located.

In one example, the third resource indication information may be used to indicate at least one of the following: a third starting RB number; a third RB number.

The third starting RB number is the number of RBs between the starting RB of the second frequency domain resource and the starting RB of the first subband.

The third number of RBs is the number of RBs included in the second frequency domain resources.

It should be noted that the third resource indication information can be used to indicate the third starting RB number, and the third RB number can be determined based on the protocol agreement or other predefined methods. Alternatively, the third resource indication information can be used to indicate the third RB number, and the third starting RB number can be determined based on the protocol agreement or other predefined methods. Alternatively, the third resource indication information can be used to indicate the third starting RB number and the third RB number.

When the terminal is located in the second type of time unit, the terminal determines that the frequency domain resource occupied when transmitting the uplink information is the second frequency domain resource, and the manner of determining the second frequency domain resource is as follows:

The second frequency domain resources occupied by the second time unit with an even index value are related to the third starting RB number and the third RB number.

The second frequency domain resources occupied by the second time unit whose index value is an odd number are not only related to the third starting RB number and the third RB number, but also related to the third frequency domain offset indicated by the third frequency hopping indication information.

In this disclosure, it is assumed is the index value of the second time unit, that is is the index value of the SBFD slot. The terminal can use Formula 3 to determine the index value of the starting RB for transmitting uplink information in the second time unit.

in, is the third starting RB number, is the third frequency domain offset indicated by the third frequency hopping indication information, is the number of RBs occupied by the first subband.

It can be understood that, in the second time unit whose index value is an even number, the terminal determines that the index value of the starting RB of the second frequency domain resource occupied when transmitting the uplink information is In the second time unit where the index value is an odd number, the terminal determines that the index value of the starting RB of the second frequency domain resource occupied when transmitting the uplink information is

It refers to the third number of RBs, that is, the number of RBs included in the second frequency domain resources.

in, and It is determined based on the frequency domain resource range occupied by the first sub-band. In this embodiment, and It can be determined based on the third resource indication information indicated by the frequency domain resource indication information sent by the base station.

in, It can be determined based on Table 2. For example, the value of m is 2, that is, the third frequency hopping indication information occupies 2 bits in the frequency domain resource indication information. The bit values corresponding to the first 2 bits in the frequency domain resource indication information are 01. Based on Table 2, it can be seen that the frequency hopping offset corresponding to the bit value "01" is The terminal determines the third frequency domain offset

The terminal starts at the second time unit with an even index value. RB starts and occupies RBs are used to transmit uplink information. In the second time unit with an odd index value, the index value is RB starts and occupies RBs are used to transmit uplink information, as shown in FIG4C .

When the terminal is located in a time unit of the first type, the terminal determines that the frequency domain resource occupied when transmitting the uplink information is the first frequency domain resource, wherein the first frequency domain resource can be determined based on at least one of the fourth starting RB number, the fourth RB number, and the fourth frequency domain offset. The specific determination method is as follows:

The first frequency domain resources occupied by the terminal in the first time unit whose index value is an even number are related to the fourth starting RB number and the fourth RB number, wherein the fourth starting RB number is the number of RBs between the starting RB of the first frequency domain resources occupied by the uplink information in the first time unit and the starting RB of the uplink BWP, and the fourth RB number is the number of RBs included in the first frequency domain resources occupied by the uplink information in the first time unit.

In one example, the fourth starting RB number may be equal to the third starting RB number.

In one example, the fourth number of RBs may be equal to the third number of RBs.

The first frequency domain resource occupied by the terminal in the first time unit with an odd index value is related to the fourth starting RB number and the fourth RB number, and is also related to the fourth frequency domain offset indicated by the fourth frequency hopping indication information. The number of bits n occupied by the fourth frequency hopping indication information is determined based on the number of RBs occupied by the uplink BWP.

In the present disclosure, the value of n can be determined based on Table 1. The specific determination method has been introduced in the above embodiment and will not be repeated here.

m≤n has been introduced before. Since the frequency domain resource indication information sent by the base station is used to indicate the second frequency domain resource, and the number of bits m occupied by the third frequency hopping indication information is less than or equal to n, in one example, when m is equal to n, the terminal can determine that the fourth frequency hopping indication information is the same as the third frequency hopping indication information. In another example, when m is less than n, the terminal can add P preset bit values at the specified position of the third frequency hopping indication information to obtain the fourth frequency hopping indication information.

Wherein, P can be a non-negative integer.

In an example, P may be 0, and in this case the terminal determines the fourth frequency hopping indication information based on a predefined correspondence between the third frequency hopping indication information and the fourth frequency hopping indication information.

For example, the corresponding relationship includes: when the third frequency hopping indication information is 0, the corresponding fourth frequency hopping indication information can be 00, and when the third frequency hopping indication information is 1, the corresponding fourth frequency hopping indication information can be 01. The terminal can determine that the corresponding fourth frequency hopping indication information is "00" based on the third frequency hopping indication information "0" and the above corresponding relationship.

For another example, the corresponding relationship includes: when the third frequency hopping indication information is 0, the corresponding fourth frequency hopping indication information can be 10, and when the third frequency hopping indication information is 1, the corresponding fourth frequency hopping indication information can be 11. The terminal can determine that the corresponding fourth frequency hopping indication information is "10" based on the third frequency hopping indication information "0" and the above corresponding relationship.

The above is only an exemplary description. In actual applications, other methods of determining P and then determining the fourth frequency hopping indication information should also fall within the protection scope of the present disclosure.

In another example, P may be (n-m), and the designated position may be a position before, after, or in the middle of the third frequency hopping indication information, which is not limited in the present disclosure. The preset bit value may be 0 or 1, and preferably, the preset bit value is 0. It should be noted that the preset bit is a bit added by the terminal when parsing the indication information, and no corresponding changes are made to the specific indication bit of the base station.

For example, the third frequency hopping indication information indicated by the base station occupies m bits, m is 1, and the corresponding bit value is "0", n The value of is 2, and the terminal may add a preset bit value before or after "0" to obtain the fourth frequency hopping indication information, for example, the fourth frequency hopping indication information is "00" or "10".

In another example, when m is less than n, the terminal may obtain the fourth frequency hopping indication information based on a predefined relationship between the third frequency hopping indication information and the fourth frequency hopping indication information, such as a corresponding relationship agreed upon by a protocol, and based on the third frequency hopping indication information. In one possible exemplary embodiment, the corresponding relationship may be shown in Table 3 or Table 4:

Table 3 Correspondence between the fourth frequency hopping indication information and the third frequency hopping indication information when m is less than n

Table 4 Correspondence between the fourth frequency hopping indication information and the third frequency hopping indication information when m is less than n

It is worth noting that the predefined relationship in Table 3 or Table 4 is an exemplary description of one of the corresponding relationships, and other corresponding relationships are also within the protection scope of the present invention.

After determining the fourth frequency hopping indication information, the terminal may determine a fourth frequency domain offset RB _offset ′ based on Table 1.

For example, the bit value corresponding to the fourth frequency hopping indication information is "10", then based on Table 1, it can be determined that (In the present disclosure, if the frequency domain offset is a negative value, it can be offset downward).

In this disclosure, it is assumed is the index value of the first time unit, that is is the index value of the non-SBFD slot. The terminal can use the following formula 4 to determine the index value of the starting RB for transmitting uplink information in the first time unit:

RB _start ′ is the fourth starting RB number, RB _offset ′ is the fourth frequency domain offset indicated by the fourth frequency hopping indication information, The number of RBs occupied by the uplink BWP.

Understandably, It refers to the first time unit with an even index value. At this time, the index value of the starting RB of the first frequency domain resource occupied by the terminal when transmitting uplink information is RB _start ′. It refers to the first time unit with an odd index value. At this time, the index value of the starting RB of the first frequency domain resource occupied when transmitting uplink information is

L _RB ′ refers to the fourth number of RBs, that is, the number of RBs included in the first frequency domain resources.

in,

The RB _offset ′ may be determined based on Table 2. The specific determination method has been introduced in the above embodiment and will not be described again here.

In the first time unit with an even index value, the terminal occupies L _RB ′ RBs to transmit uplink information, starting from the RB with an index value of RB′ _start , and in the first time unit with an odd index value, starting from the RB with an index value of Starting from the RB of , L _RB ′ RBs are occupied to transmit uplink information, as shown in FIG. 4D .

In the above embodiment, the frequency domain resource indication information indicates the second frequency domain resource occupied by the uplink information during frequency hopping transmission within the range of frequency domain resources occupied by the first sub-band. The terminal can determine the frequency domain resources occupied when the uplink information is frequency hopping transmitted across time units on different types of time units, thereby ensuring that the terminal and the base station have a consistent understanding of the frequency domain resources, thereby improving the feasibility and reliability of communication in the SBFD scenario.

In some optional embodiments, when the terminal transmits uplink information across time units, two types of time units may be encountered. When the frequency domain resource indication information is used to indicate the first frequency domain resource, the terminal may determine the corresponding frequency domain resource in the following manner:

In a possible implementation manner, the frequency domain resource indication information is used to indicate at least one of the following: first resource indication information; first frequency hopping indication information.

The first resource indication information is used to indicate the first frequency domain resource occupied by the uplink information in the first time unit. It should be noted that the first time unit is a first type of time unit, that is, a non-SBFD time unit.

The first frequency hopping indication information is used to indicate a third frequency domain offset of a hop on a first type of time unit relative to a previous hop on the first type of time unit when transmitting the uplink information. It should be noted that the number of bits occupied by the first frequency hopping indication information is n, and n is determined based on the number of RBs occupied by the uplink BWP.

In an example, the first time unit may include but is not limited to at least one of the following time units: a time unit where the index value of the uplink information is an even number; and a time unit where the first hop of the uplink information is located.

When the terminal is located in a time unit of the first type, that is, in a non-SBFD time unit, the terminal may determine the first frequency domain resource occupied when transmitting the uplink information based on the following mechanism:

In this disclosure, it is assumed Used to indicate the hop count index value in the first time unit. The terminal can use Formula 5 to determine the index value of the starting RB for transmitting uplink information in the first time unit.

in, 0, 1, 2, 3, ... are respectively used to indicate the first jump, the second jump, the third jump, the fourth jump, etc. in the first time unit.

Understandably, correspond The index value is an even number, which means an odd-numbered jump in the first time unit, such as the 1st, 3rd, and so on jumps. correspond The index value is an odd number, which refers to an even-numbered jump in the first time unit, such as the 2nd, 4th, 6th, ... jump.

For example, in FIG. 5A , the first time unit includes slot#0 and slot#2, then When it is 0, it indicates the first hop in the first time unit slot#0. When it is 1, it is used to indicate the second hop on the first time unit slot#2.

In one example, the first resource indication information included in the frequency domain resource indication information sent by the base station can be used to indicate at least one of the following: a first starting RB number; a first RB number.

The first starting RB number is the number of RBs between the starting RB of the first frequency domain resource and the starting RB of the uplink BWP.

The first number of RBs is the number of RBs included in the first frequency domain resources, that is, the number of RBs occupied by uplink information.

Assume that the uplink information is frequency-hopping transmitted on slot#0 to slot#3, where only slot#0 and slot#2 are the first time units, i.e., they belong to the non-SBFD time units. The first frequency-hopping indication information indicates the first frequency domain offset of a hop of the uplink information on slot#2 relative to a hop on slot#0, as shown in FIG5A.

The number of bits occupied by the first frequency hopping indication information in the frequency domain resource indication information is n, and n is determined based on the number of RBs occupied by the uplink BWP.

For example, when the number of RBs occupied by the uplink BWP is less than 50, as shown in Table 1, n is 1, and its specific bit value can be determined by the terminal based on the bit value of the first n bits in the frequency domain resource indication information. Since n is 1, it is assumed that the bit value of the first bit in the frequency domain resource indication information is 0. According to Table 1, the frequency hopping offset (offset) is At this time, the terminal can determine the first frequency hopping offset

For another example, when the number of RBs occupied by the uplink BWP is greater than or equal to 50, referring to Table 1, n is 2, and its specific bit value can be determined by the terminal based on the bit value of the first n bits in the frequency domain resource indication information. Since n is 2, assuming that the bit values of the first 2 bits in the frequency domain resource indication information are 01, according to Table 1, the frequency hopping offset is At this time, the terminal can determine the first frequency hopping offset The number of RBs occupied by the uplink BWP.

The number of bits occupied by the second frequency hopping indication information is m, and m is determined based on the number of RBs occupied by the first subband. m is less than or equal to n.

Exemplarily, if the uplink information adopts resource allocation type 1 (type), the first resource indication information may be a first RIV. The terminal determines the starting RB number and the continuous RB number corresponding to the first RIV based on the correspondence between different RIVs and different starting RB numbers and continuous RB numbers, and determines the determined starting RB number as the first starting RB number, and determines the determined continuous RB number as the first RB number.

Assuming that the first starting RB number RB _start is determined based on the frequency domain resource indication information, and the first RB number is L _RB , as shown in Figure 5B, on the uplink BWP (assuming that the starting RB index value of the uplink BWP is 0), the terminal determines that the first frequency domain resources occupied by the first hop on slot#0 include: starting from RB _start , all RBs with a continuously occupied RB number of L _RBs .

In addition, the first frequency domain resources occupied by the second hop of the terminal on slot#2 include: all RBs whose number of RBs continuously occupied is L _RBs starting from (RB _start + RB _offset ), wherein RB _offset is the first frequency domain offset indicated by the first frequency hopping indication information, as also shown in FIG. 5B .

Or RB _offset can be a negative value, and the first frequency domain resources occupied by the second hop of the terminal on slot#2 include: all RBs starting from (RB _start - RB _offset ) and continuously occupying L _RBs . Among them, RB _offset is the first frequency domain offset indicated by the first frequency hopping indication information (not shown in FIG. 5B ).

When the terminal is located in the second type of time unit, the terminal determines that the frequency domain resource occupied when transmitting the uplink information is the second frequency domain resource, wherein the second frequency domain resource can be determined based on at least one of the second starting RB number, the second RB number and the second frequency domain offset. The specific determination method is as follows:

First, the terminal may determine a second starting number of RBs, where the second starting number of RBs is the number of RBs between the second frequency domain resources and a starting RB of the first subband.

In an example, the second starting RB number may be equal to the first starting RB number mentioned above.

Of course, the second starting RB number may also be associated with the first starting RB number, for example, offset again on the basis of the first starting RB number, which is not limited in the present disclosure.

For example, the first starting RB number determined previously is RB _start , and the terminal determines the second starting RB number

Secondly, the terminal may determine a second number of RBs, where the second number of RBs is the number of RBs included in the second frequency domain resources.

In one example, the second number of RBs may be equal to the first number of RBs described above.

For example, the first RB number previously determined is L _RB , and the terminal determines the second RB number

Again, the terminal may determine second frequency hopping indication information, where the second frequency hopping indication information is used to indicate a second frequency domain offset of a hop on a second type of time unit relative to a previous hop on the second type of time unit when transmitting the uplink information.

The number of bits m occupied by the second frequency hopping indication information may be determined based on the number of RBs occupied by the first subband.

In the embodiment of the present disclosure, the number of RBs occupied by the first subband is Second frequency hopping indication information The bit value (the bit value of m bits) and the corresponding indicated frequency hopping offset can be referred to as shown in the above Table 2.

In one example, since the frequency domain resource indication information is indicated based on the uplink BWP and m≤n, after determining the first frequency hopping indication information (the number of occupied bits is n), the terminal can determine the second frequency hopping indication information based on the bit value corresponding to the m least significant bits in the first frequency hopping indication information.

For example, m and n are both equal to 2, and the bit value corresponding to the n least significant bits in the first frequency hopping indication information N _{UL,hop is} 01, that is, the bit value of the first frequency hopping indication information N UL,hop is 01, then the terminal determines that the bit value corresponding to the m least significant bits in the first frequency hopping indication information N _UL,hop is also 01, that is, the second frequency hopping indication information The corresponding bit value is 01. Based on Table 2, the second frequency domain offset can be determined.

For another example, m is less than n, and the bit value corresponding to the n least significant bits in the first frequency hopping indication information N _UL,hop is 01, then the terminal determines that the bit value corresponding to the m least significant bits in the first frequency hopping indication information N _UL,hop is also 1, that is, the second frequency hopping indication information The corresponding bit value is 1. Based on Table 2, the second frequency domain offset can be determined. at this time

In another example, since the frequency domain resource indication information is indicated based on the uplink BWP and m≤n, after determining the first frequency hopping indication information (the number of occupied bits is n), the terminal can determine the second frequency hopping indication information based on the bit value corresponding to the m most significant bits in the first frequency hopping indication information.

For example, m and n are both equal to 2, and the bit value corresponding to the n most significant bits in the first frequency hopping indication information is 01, then the terminal determines that the bit value corresponding to the m most significant bits in the first frequency hopping indication information is also 01, and the second frequency domain offset can be determined based on Table 2. And at this time

For another example, m is less than n, and the bit value corresponding to the n most significant bits in the first frequency hopping indication information is 01, then the terminal determines that the bit value corresponding to the m most significant bits in the first frequency hopping indication information is also 0, and based on Table 2, the second frequency domain offset can be determined.

Shift at this time

The present disclosure does not limit the execution order of determining the second starting RB number, the second RB number, and the second frequency hopping indication information.

After determining the second starting RB number, the second RB number, and the second frequency hopping indication information, the terminal may determine the second frequency domain resource according to the following formula 6 based on at least one of the second starting RB number, the second RB number, and the second frequency domain offset:

in, 0, 1, 2, 3, ... are respectively used to indicate the first jump, the second jump, the third jump, the fourth jump, etc. on the second time unit.

Understandably, Refers to the odd-numbered jumps on the second time unit, such as the 1st, 3rd, ... jumps, It refers to the even-numbered jumps in the second time unit, such as the 2nd, 4th, ... jumps.

For example, in FIG. 5A , the second time unit includes slot#1 and slot#3. When it is 0, it indicates the first jump in the second time unit, and the first jump is located in slot #1. When it is 1, it is used to indicate the second jump in the second time unit, and the second jump is located in slot #3.

For example, as shown in FIG. 5C , assuming that a first starting RB number RB _start is determined based on the frequency domain resource indication information, and the first RB number is L _RB , the terminal may determine a second starting RB number Second RB number The terminal is on the first subband (assuming that the starting RB index value of the first subband is also 0), and the terminal determines that the first hop on the second time unit is located on slot#1, and the occupied second frequency domain resources include: At the beginning, the number of RBs continuously occupied is All RBs.

In addition, the second hop of the terminal on the second time unit is located on slot#3, and the occupied second frequency domain resources include: At the beginning, the number of RBs continuously occupied is All RBs. Among them, It is the second frequency domain offset indicated by the second frequency hopping indication information.

or It can take a negative value. The first frequency domain resources occupied by the second hop of the terminal on slot#2 include: At the beginning, the number of RBs continuously occupied is RB _offset is the first frequency domain offset indicated by the first frequency hopping indication information (not shown in FIG5C ).

That is, the terminal can use Formula 6 to determine the starting RB of the second frequency domain resource in slot#1 and slot#3.

In the above embodiment, the frequency domain resource indication information indicates the first frequency domain resource occupied by the uplink information during frequency hopping transmission within the range of frequency domain resources occupied by the uplink BWP. The terminal can determine the frequency domain resources occupied when the uplink information is frequency hopping transmitted across time units on different types of time units, ensuring that the terminal and the base station have a consistent understanding of the frequency domain resources, thereby improving the feasibility and reliability of communication in the SBFD scenario.

In some optional embodiments, when the terminal transmits uplink information across time units, two types of time units may be encountered. When the frequency domain resource indication information is used to indicate the second frequency domain resource, the terminal may determine the corresponding frequency domain resource in the following manner:

In a possible implementation manner, the frequency domain resource indication information is used to indicate at least one of the following: third resource indication information; third frequency hopping indication information.

The third resource indication information is used to indicate the second frequency domain resource occupied by the uplink information in the second time unit. It should be noted that the second time unit is a second type of time unit, that is, a SBFD time unit.

The third frequency hopping indication information is used to indicate a third frequency domain offset of a hop on a second type of time unit relative to a previous hop on the second type of time unit when transmitting the uplink information. It should be noted that the number of bits occupied by the third frequency hopping indication information is m, and m is determined based on the number of RBs occupied by the first subband.

In an example, the second time unit may include but is not limited to at least one of the following time units: a time unit where the index value of the uplink information is an even number; and a time unit where the first hop of the uplink information is located.

Exemplarily, the third resource indication information is used to indicate uplink information, such as the second frequency domain resources occupied by PUSCH in the time unit with index values 0, 2, 4, 6, ..., and/or the third resource indication information is used to indicate uplink information, such as the second frequency domain resources occupied by PUSCH in the time unit where the first hop of PUSCH is located.

Exemplarily, assume that the uplink information is frequency-hopping transmitted on slot#0 to slot#3, where only slot#1 and slot#3 are the second time unit, i.e., the SBFD time unit, and the third frequency-hopping indication information indicates the third frequency domain offset of a hop of the uplink information on slot#3 relative to a hop on slot#1, as shown in FIG5D.

The number of bits occupied by the third frequency hopping indication information in the frequency domain resource indication information is m, and m is determined based on the number of RBs occupied by the first sub-band.

For example, when the number of RBs occupied by the first subband is less than 50, as shown in Table 2, the value of m is 1, and its specific bit value can be determined by the terminal based on the bit value of the first m bits in the frequency domain resource indication information. Since m is 1, it is assumed that the bit value of the first bit in the frequency domain resource indication information is 0, that is, the third frequency domain indication information The bit value of is 1. According to Table 2, the frequency hopping offset is At this time, the terminal can determine the third frequency hopping offset

For another example, when the number of RBs occupied by the first subband is greater than or equal to 50, referring to Table 2, m is 2, and its specific bit value can be determined by the terminal based on the bit values of the first m bits in the frequency domain resource indication information. Assuming that the bit values of the first 2 bits in the frequency domain resource indication information are 10, that is, the third frequency domain indication information The bit value is 10. According to Table 2, the frequency hopping offset is At this time, the terminal can determine the third frequency hopping offset

When the terminal is located in the second type of time unit, that is, in the SBFD time unit, the terminal may determine the second frequency domain resource occupied when transmitting the uplink information based on the following mechanism:

In this disclosure, it is assumed is the index value of the second time unit, that is is the index value of the SBFD slot. The terminal can use Formula 7 to determine the index value of the starting RB for transmitting uplink information in the second time unit.

in, is the third starting RB number, is the third frequency domain offset indicated by the third frequency hopping indication information, is the number of RBs occupied by the first subband.

in, 0, 1, 2, 3, ... are respectively used to indicate the first jump, the second jump, the third jump, the fourth jump, etc. on the second time unit.

Understandably, Refers to the odd-numbered jumps on the second time unit, such as the 1st, 3rd, ... jumps, It refers to the even-numbered jumps in the second time unit, such as the 2nd, 4th, ... jumps.

In one example, the third resource indication information may be used to indicate at least one of the following: a third starting RB number; a third RB number.

The third starting RB number is the number of RBs between the starting RB of the second frequency domain resource and the starting RB of the first subband.

The third number of RBs is the number of RBs included in the second frequency domain resources.

Exemplarily, if the uplink information adopts resource allocation type 1 (type), the third resource indication information may be the second RIV. The terminal determines the starting RB number and the continuous RB number corresponding to the second RIV based on the correspondence between different RIVs and different starting RB numbers and continuous RB numbers, and determines the determined starting RB number as the third starting RB number, and determines the determined continuous RB number as the third RB number.

Assume that the third starting RB number is determined based on the frequency domain resource indication information The third RB number is 5E, on the first subband (assuming that the starting RB index value of the first subband is 0), the terminal determines that the first hop on the second time unit is located on slot#1, and the second frequency domain resources occupied thereon include: At the beginning, the number of RBs continuously occupied is All RBs.

In addition, the second hop of the terminal on the second time unit is located on slot#3, and the occupied second frequency domain resources include: At the beginning, the number of RBs continuously occupied is All RBs. Among them, It is the third frequency domain offset indicated by the third frequency hopping indication information.

certainly, It can take a negative value. The first frequency domain resources occupied by the second hop of the terminal on slot#2 include: At the beginning, the number of RBs continuously occupied is RB _offset is the first frequency domain offset indicated by the first frequency hopping indication information (not shown in FIG5E ).

When the terminal is located in a time unit of the first type, that is, in a non-SBFD time unit, the terminal may determine the first frequency domain resource occupied when transmitting the uplink information based on the fourth starting RB number, the fourth RB number, and the fourth frequency hopping indication information:

First, the terminal may determine a fourth starting RB number, where the fourth starting RB number is the number of RBs between a starting RB of the first frequency domain resource and a starting RB of the uplink BWP.

In an example, the fourth starting RB number may be equal to the third starting RB number mentioned above.

Of course, the fourth starting RB number may also be associated with the third starting RB number, for example, offset again on the basis of the third starting RB number, which is not limited in the present disclosure.

Exemplarily, the third starting RB number previously determined is The terminal determines the fourth starting RB number

Secondly, the terminal may determine a fourth number of RBs, where the fourth number of RBs is the number of RBs included in the first frequency domain resources.

In one example, the fourth number of RBs may be equal to the third number of RBs described above.

Exemplarily, the third RB number previously determined is The terminal determines the fourth RB number

Again, the terminal may determine fourth frequency hopping indication information, where the fourth frequency hopping indication information is used to indicate a fourth frequency domain offset of a hop on a first type of time unit relative to a previous hop on the first type of time unit when transmitting the uplink information.

The number of bits n occupied by the fourth frequency hopping indication information may be determined based on the number of RBs occupied by the uplink BWP.

As analyzed before, m≤n.

In the embodiment of the present disclosure, the frequency domain resource indication information sent by the base station indicates the third frequency hopping indication information with the occupied bit number m. In the above embodiment, the frequency domain resource indication information indicates the first frequency hopping indication information with the occupied bit number n.

In one example, if the terminal determines that m is equal to n, the terminal may determine that the fourth frequency hopping indication information is the same as the third frequency hopping indication information. Accordingly, the fourth frequency domain offset RB _offset ′ is equal to the third frequency domain offset equal.

In another example, if the terminal determines that m is less than n, the terminal can add P preset bit values at the specified position of the third frequency hopping indication information to obtain the fourth frequency hopping indication information. It is worth noting that the preset bits are bits added by the terminal when parsing the indication information, and no corresponding changes are made to the specific indication bits.

The correspondence may be, for example, as shown in Table 3 or Table 4. The scheme for determining the fourth frequency hopping indication information based on Table 3 or Table 4 has been introduced in the above embodiment and will not be repeated here.

For example, m is 1, n is 2, P is 0, and the bit value corresponding to the third frequency hopping indication information is 1. Based on Table 3, it can be determined that the fourth frequency hopping indication information is 01.

The terminal can determine the frequency domain resources occupied when the uplink information is frequency hopping transmitted across time units on different types of time units, thereby ensuring that the terminal and the base station have a consistent understanding of the frequency domain resources, thereby improving the feasibility and reliability of communication in the SBFD scenario.

The manner of determining RB _start and RB _offset on the uplink BWP or uplink subband has been introduced in the above embodiments and will not be described again here.

In the above embodiment, no matter the frequency domain resource indication information indicates the first frequency domain resource occupied by the uplink information frequency hopping transmission within the frequency domain resource range occupied by the uplink BWP, or indicates the second frequency domain resource occupied by the uplink information frequency hopping transmission within the frequency domain resource range occupied by the uplink subband, the terminal can determine the frequency domain resource occupied by the uplink information when the uplink information is frequency hopping transmitted across time units on different types of time units, ensuring that the terminal and the base station have the same understanding of the frequency domain resource, thereby improving the feasibility and reliability of communication in the SBFD scenario. The resource indication method provided by the present disclosure is introduced from the base station side.

The present disclosure provides a resource indication method, as shown in FIG6 , which is a flow chart of a resource indication method according to an embodiment, which can be executed by a base station. The method may include the following steps:

In step 601, in response to scheduling frequency hopping transmission of uplink information across time units for a terminal, frequency domain resource indication information is sent to the terminal.

In an embodiment of the present disclosure, the frequency domain resource indication information is used by the terminal to determine the frequency domain resources occupied when transmitting the uplink information, and the frequency domain resources are the first frequency domain resources within the frequency domain resource range occupied by the uplink partial bandwidth BWP or the second frequency domain resources within the frequency domain resource range occupied by the first sub-band.

In a possible implementation, the base station sends a first message including an FDRA field to the terminal, and the first message may be an RAR message, which is not limited in the present disclosure. The frequency domain resource indication information is sent to the terminal via the FDRA field.

In a possible implementation, the uplink information includes but is not limited to PUSCH, PUCCH, SRS, etc.

After receiving the frequency domain resource indication information, the terminal determines the frequency domain resources occupied when transmitting the uplink information based on the frequency domain resource indication information when performing frequency hopping transmission on the uplink information across time units.

In a possible implementation manner, the frequency domain resource may be a first frequency domain resource, and the first frequency domain resource is located within a frequency domain resource range occupied by an uplink BWP.

In another possible implementation, the frequency domain resource may be a second frequency domain resource, and the second frequency domain resource is located within the frequency domain resource range occupied by the first subband. The first subband is a UL subband, and when the terminal is configured to perform uplink transmission on the first subband, the terminal needs to perform uplink transmission based on the second frequency domain resource. Exemplarily, the first subband is located on a SBFD time unit in the time domain, wherein the SBFD time unit is in units of slots, symbols, frames, subframes, etc., and the present disclosure does not limit this. In a possible implementation, the base station determines, in response to determining that the terminal is located on a first type of time unit, that the frequency domain resource occupied by the terminal when transmitting PUSCH is the first frequency domain resource.

The meanings of the non-SBFD time unit and the SBFD time unit have been introduced on the terminal side and will not be repeated here.

In a possible implementation, the frequency domain resource indication information sent by the base station can be used to directly indicate the first frequency domain resource, that is, the base station indicates the first frequency domain resource based on the frequency domain resource range occupied by the uplink BWP. Accordingly, if the terminal is in a first type of time unit, the terminal directly determines the first frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information. If the terminal is in a second type of time unit, the terminal cannot directly determine the second frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information.

In another possible implementation, the frequency domain resource indication information sent by the base station can be used to directly indicate the second frequency domain resource, that is, the base station indicates the second frequency domain resource based on the frequency domain resource range occupied by the first subband. Accordingly, if the terminal is in the second type of time unit, the terminal directly determines the second frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information. If the terminal is in the first type of time unit, the terminal cannot directly determine the first frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information.

It should be noted that the number of bits occupied by the first frequency hopping indication information in the frequency domain resource indication information is n, and n is determined based on the number of RBs occupied by the uplink BWP.

In an example, the first time unit may include but is not limited to at least one of the following time units: a time unit where the index value of the uplink information is an even number; and a time unit where the first hop of the uplink information is located.

The number of bits occupied by the first frequency hopping indication information in the frequency domain resource indication information is n, and n is determined based on the number of RBs occupied by the uplink BWP.

In one example, the first resource indication information may be used to indicate at least one of the following: a first starting RB number; a first RB number.

The first starting RB number is the number of RBs between the starting RB of the first frequency domain resource and the starting RB of the uplink BWP.

After determining the first RIV based on the correspondence between different RIVs and different starting RB numbers and continuous RB numbers, the base station sends the first RIV as the first resource indication information to the terminal.

When the base station determines that the terminal is located in a first type of time unit, that is, in a non-SBFD time unit, the base station can determine the first frequency domain resources occupied by the terminal when transmitting the uplink information. The specific determination method is similar to the method in which the terminal side determines the first frequency domain resources based on the frequency domain resource indication information, and will not be repeated here.

When it is determined that the terminal is located in the second type of time unit, that is, in the SBFD time unit, the base station can determine the second frequency domain resources occupied by the terminal when transmitting the uplink information. The specific determination method is similar to the method of determining the second frequency domain resources on the terminal side, which will not be repeated here.

In the above embodiment, the frequency domain resource indication information indicates the first frequency domain resource occupied by the uplink information during frequency hopping transmission within the range of frequency domain resources occupied by the uplink BWP. The base station can determine that the terminal is in different types of time units and the frequency domain resources occupied when transmitting uplink information across time units, thereby ensuring that the terminal and the base station have a consistent understanding of the frequency domain resources, thereby improving the feasibility and reliability of communication in the SBFD scenario.

The third frequency hopping indication information is used to indicate a third frequency domain offset of a hop on a second type of time unit relative to a previous hop on the second type of time unit when transmitting the uplink information. It should be noted that the number of bits occupied by the third frequency hopping indication information is m, and m is determined based on the number of RBs occupied by the first subband.

In an example, the second time unit may include but is not limited to at least one of the following time units: The time unit whose index value is an even number; the time unit where the first hop of the uplink information is located.

The number of bits occupied by the third frequency hopping indication information in the frequency domain resource indication information is m, and m is determined based on the number of RBs occupied by the first sub-band.

This embodiment considers that Msg 3 is based on inter-slot or intra-slot frequency hopping, and the terminal determines the FDRA domain indicated in the RAR and other signaling based on the configuration of UL BWP, thereby determining the frequency domain resource indication information. If the terminal is in the SBFD time unit, the terminal performs uplink information transmission within the frequency domain resource range occupied by the first subband, and the first subband is UL subband. UL subband refers to the frequency domain resource range formed by the intersection of the subband configured for uplink transmission and UL BWP in the frequency domain range, that is, the frequency domain resource range occupied by the first subband for uplink information transmission of the terminal is less than or equal to the frequency domain resource range occupied by UL BWP.

If the terminal is in the first type of time unit, that is, the slot (or symbol) where non-SBFD is located, the terminal determines the frequency domain resources occupied by PUSCH transmission based on the UL BWP and the FDRA field of the indication signaling. For example, the first RB number L _RB and the first starting RB number RB _start are directly determined based on the frequency domain resource indication information. Among them, L _RB is the number of RBs included in the PUSCH transmission, RB _start is the number of RBs between the starting RB of the first frequency domain resource and the starting RB of the uplink BWP, and the corresponding first frequency domain offset RB _offset can be determined based on Table 1.

Under the condition that m and n are equal, the terminal determines the second frequency hopping indication information N _UL,hop based on the bit value of the first frequency hopping indication information N UL,hop in the FDRA domain. The bit value of the corresponding bit, The corresponding relationship between the bit value of the corresponding bit position and the indicated second frequency domain offset is shown in Table 2;
