detailed description

The technical solutions in the embodiments of the present disclosure will be described clearly and completely in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative efforts fall within the protection scope of the present disclosure.

Referring to FIG. 1, FIG. 1 is a flowchart of a transmission method provided by an embodiment of the present disclosure, which is used for a sender device, where the sender device is a network-side device or terminal. As shown in FIG. 1, the method includes the following step:

Step 101: Repeat transmission of N physical shared channels; N is an integer greater than 1;

The above-mentioned physical shared channel may be a physical uplink shared channel PUSCH or a physical downlink shared channel PDSCH. Specifically, when the sending end device is a network side device, the repeated transmission of the N physical shared channels may be repeated transmission of N PDSCHs to the terminal, and when the sending end device is the terminal, the repeated transmission of the N physical shares The channel may be that N PUSCHs are repeatedly transmitted to the network side device.

For PUSCH, the method of the embodiment of the present disclosure is applicable to both PUSCH based on uplink authorization and PUSCH based on configuration authorization. In the following description, PUSCH refers to these two types of PUSCH.

It should be understood that the above-mentioned N physical shared channels that are repeatedly transmitted may be distributed in one time slot or in multiple time slots.

In a specific embodiment of the present disclosure, the physical shared channel may be a shared channel based on non-slot scheduling, because a shared channel based on non-slot scheduling may be transmitted multiple times in a time slot, and these transmissions can be located in multiple The time slot, therefore, the problem of transmission conflict is more prominent, and the method of the embodiment of the present disclosure can better solve the problem of transmission conflict.

In this embodiment, the mapping strategy of the repeatedly transmitted physical shared channel to the transmission resource includes two requirements:

1. In the time domain, the transmission resources of any one of the N physical shared channels repeatedly transmitted above are continuously distributed in the time domain;

2. In the time domain, the transmission resource of any one of the above-mentioned N physically shared channels repeatedly transmitted is located in the same time slot.

In other words, the transmission resources of any physical shared channel can neither be separated nor span time slots.

The following uses PUSCH repeated transmission as an example for illustration.

As shown in FIG. 2a, taking the repeated transmission of 4 PUSCHs as an example, it is assumed that the starting symbol of the repeated transmission is the symbol No. 8 in the first time slot (time slot n). At this time, any PUSCH needs to be continuously distributed in the time domain and located in the same time slot. Therefore, the first three PUSCHs can be transmitted in the first time slot (time slot n), which are located in

symbols

8, 9, 10, 11 and 12, 13 respectively, while the fourth PUSCH The second and third symbols in the second time slot (time slot n + 1) are transmitted. Each PUSCH is continuously distributed in the time domain and located in the same time slot. Among them, a PUSCH has a time domain length of 2, F represents a flexible symbol, U represents an uplink symbol, and D represents a downlink symbol.

As shown in FIG. 2b again, taking the repeated transmission of 4 PUSCHs as an example, it is assumed that the starting symbol of the repeated transmission is the symbol No. 7 in the time slot n. At this time, the first PUSCH, the second PUSCH, and the third PUSCH are in the 7th, 8th symbols, 9th, 10th symbols, and 11th, 12th symbols in the first time slot (slot n), respectively. transmission. Since there is only one uplink symbol in the first time slot that can be transmitted, if the 13th symbol is allocated to the fourth PUSCH, the transmission resources of the fourth PUSCH will inevitably appear cross-slot and discontinuous, which does not satisfy the mapping Strategy. Therefore, in a specific embodiment of the present disclosure, the fourth PUSCH can only be transmitted in the second and third symbols of the second time slot (time slot n + 1).

As shown in FIG. 2c, taking repeated transmission of 4 PUSCHs as an example, it is assumed that the starting symbol of repeated transmission is the symbol No. 2 in the second time slot (time slot n + 1). At this time, the first PUSCH, the second PUSCH, and the third PUSCH are transmitted in the second, third, and fourth symbols of the second time slot (time slot n + 1), respectively. If the symbol No. 6 is allocated to the third PUSCH, the transmission resources of the third PUSCH will inevitably appear discontinuous, which does not satisfy the mapping strategy. Therefore, in a specific embodiment of the present disclosure, the third PUSCH and the fourth PUSCH can only be transmitted in symbols 10-13 of the second time slot (time slot n + 1).

In this way, when the transmitting end device transmits the physical shared channel with the receiving end device, it can perform repeated transmission according to the rules required by the transmission resources of any one physical shared channel specified in this embodiment to solve the transmission that occurs in the repeated transmission Conflict issues.

The above description is based on PUSCH as an example, but it is also applicable to PDSCH transmission. The difference is only in the direction of transmission resources, and the description will not be repeated here.

In the case where the sending-end device is a terminal, before repeatedly transmitting N physical shared channels, it may also receive repeated transmission instruction information from the network-side device, where the repeated transmission instruction information includes the time domain starting position S, physical sharing The length L of the channel and the N;

The transmission resources of the N physical shared channels in the time domain are determined according to the S, L, N and time slot format indication information.

In this embodiment, when the sending-end device is a terminal, the network-side device may first send repeated transmission instruction information to the terminal to indicate the terminal's time domain starting position S, the length of the physical shared channel L and the physical shared channel's time when the terminal repeatedly transmits The number N, in this way, the terminal needs to satisfy the rules required for the transmission resources of any physical shared channel according to the S, L, N and the known time slot format (that is, the symbol of each position in each time slot), In this way, the distribution of time domain resources of the N physical shared channels can be determined, and then repeated transmission can be performed according to the determined distribution of time domain resources.

For example, if the repeated transmission indication information sent by the network-side device is S = 8, L = 2, N = 4, and the known time slot format is shown in FIG. 2a, the time of the 4 PUSCHs to be repeatedly transmitted can be determined The distribution of domain resources is as follows: the first PUSCH is located on the 8th and 9th symbols on the first time slot, the second PUSCH is located on the 10th and 11th symbols on the first time slot, and the third PUSCH is on the first

time slot Symbols

12 and 13 on the first time slot are transmitted, and the fourth PUSCH is located on

symbols

2 and 3 on the second time slot.

Compared with the method of directly indicating the time-domain transmission resource of each PUSCH, the above method only needs to indicate the time-domain starting position S of the transmission resource of the first PUSCH, the length L of the physical shared channel, and the number of physical shared channels N can greatly reduce the overhead of the repeated indication information and save transmission resources.

Optionally, the time difference between the start time of the first transmission resource and the end time of the second transmission resource is less than or equal to the first threshold, and the first transmission resource is: Of the N physical shared channels, the first A starting symbol of a physical shared channel, the second transmission resource is: the end symbol of the last physical shared channel among the N physical shared channels;

or

The transmission resources of the N physical shared channels are located in the same transmission cycle;

or

The time difference between the end time of the third transmission resource and the start time of the fourth transmission resource is less than or equal to the second threshold, and the third transmission resource is: among the adjacent physical shared channels, the physical shared channel transmitted earlier For the end symbol of, the fourth transmission resource is: the starting symbol of the physical shared channel to be transmitted later in the adjacent physical shared channel.

When repeatedly transmitting the N physical shared channels, in order to ensure that the repeatedly transmitted physical shared channels meet preset time limit rules, one or more of the N physical shared channels may be discarded in order of transmission time. Specifically, different treatments can be performed according to the following three situations:

The first case is that the start of the first transmission resource is not expected when the duration from the start time of the start symbol of the first transmission to the end time of the end symbol of the last transmission exceeds a preset time interval The time difference between the moment and the end moment of the second transmission resource is less than or equal to the first threshold. Wherein, the first transmission resource is the start symbol of the first physical shared channel among the N physical shared channels, and the second transmission resource is the last physical shared channel among the N physical shared channels , The first threshold may be a pre-defined time interval. When the time difference between the start time of the first transmission resource and the end time of the second transmission resource is greater than the first threshold, the time domain position in the N physical shared channels may exceed the first Transmission resources within a threshold range are discarded.

For example, as shown in FIG. 3a, the time domain length Q of the first threshold is 16 symbols, and of the 4 physical shared channels to be repeatedly transmitted, the start symbol of the first physical shared channel starts from the fourth symbol to the fourth The difference between the reception times of the end symbols of the physical shared channel is 18 symbols, which exceeds the length specified by the first threshold. Therefore, in specific embodiments of the present disclosure, the transmission resource of the fourth physical shared channel may be discarded, and the time difference between the start time of the start symbol of the first physical shared channel and the end time of the end symbol of the third physical shared channel It is 16 symbols and does not exceed the length of the first threshold. Therefore, resource transmission from the first physical shared channel to the third physical shared channel can be reserved.

The above-mentioned strategy can be controlled by the sending end device, for example, before each PUSCH is transmitted to determine whether transmission is required. Taking the repeated transmission of 4 PUSCHs as an example, as shown in FIG. 3a, before transmitting the second PUSCH, the start time of the first transmission resource (symbol 10 in time slot n) and the second transmission resource (time Whether the time difference between the end moments of the 13th symbol in slot n) exceeds the Q value, and if the judgment result indicates that it has not been exceeded, the transmission is continued. When transmitting the fourth PUSCH, determine the start time of the first transmission resource (symbol 10 in slot n) and the end time of the second transmission resource (symbol 13 in slot n + 1) Whether the time difference between them exceeds the Q value, and the judgment result indicates that the fourth PUSCH is discarded.

The second case is that, in the case where the transmission resources of the N physical shared channels are expected to be in the same transmission cycle, the physical shared channels of the N physical shared channels that exceed the transmission cycle can be discarded. Wherein, the transmission period may be pre-configured. For example, as shown in FIG. 3b, when the first physical shared channel to the third physical shared channel of the four physical shared channels to be repeatedly transmitted are located in the same transmission period P, and the fourth physical shared channel is not completely located in the transmission During the period, the fourth physical shared channel may be discarded to ensure that the repeatedly transmitted physical shared channels are located in the same transmission period.

The above-mentioned strategy can be controlled by the sending end device, for example, before each PUSCH is transmitted to determine whether transmission is required. Taking the repeated transmission of 4 PUSCHs as an example, as shown in FIG. 3b, before transmitting the second PUSCH, it is determined whether the end symbol of the second PUSCH (symbol No. 5 in slot n + 1) is within the period P, If the judgment result indicates that it is within the period P, the transmission is continued. When the fourth PUSCH is transmitted, it is judged whether the end symbol of the fourth PUSCH (symbol 13 in slot n + 1) is located in the period P, and if the judgment result indicates that it is not in the period P, the fourth PUSCH is discarded .

The third case is that, when the time domain interval of the transmission resources of adjacent physical shared channels is not expected to exceed a preset interval, the time between the end of the third transmission resource and the start of the fourth transmission resource is specified. The time difference is less than or equal to the second threshold, wherein the third transmission resource is an adjacent physical shared channel, the end symbol of the previously transmitted physical shared channel, and the fourth transmission resource is the adjacent physical shared channel , The starting symbol of the physical shared channel transmitted later, the second threshold may be a pre-defined time domain interval. When the time difference between the third transmission resource and the fourth transmission resource is greater than the second threshold, the physical shared channel resource located after the third transmission resource among the N physical shared channels may be discarded .

For example, as shown in FIG. 3c, the time domain length O of the second threshold is 9 symbols, and of the 4 physical shared channels to be repeatedly transmitted, the end symbol of the second physical shared channel ends to the third physical The time-domain interval between the start times of the start symbols of the shared channel is 10 symbols, which exceeds the interval length specified by the second threshold. Therefore, the third physical shared channel and the fourth physical shared channel can be discarded, and Only the first physical shared channel and the second physical shared channel are reserved.

The above-mentioned strategy can be controlled by the sending end device, for example, before each PUSCH is transmitted to determine whether transmission is required. Taking the repeated transmission of 4 PUSCHs as an example, as shown in FIG. 3c, before transmitting the second PUSCH, the start time of the third transmission resource (symbol 11 in time slot n) and the fourth transmission resource (time Whether the time difference between the end times of the twelfth symbol in slot n) exceeds the value of O, and if the judgment result indicates that it has not been exceeded, the transmission is continued. When transmitting the third PUSCH, determine the start time of the third transmission resource (symbol 13 in slot n) and the end time of the fourth transmission resource (symbol 10 in slot n + 1) Whether the time difference between them exceeds the value of 0, and the judgment result indicates that the third PUSCH and the fourth PUSCH are discarded.

In this way, in this embodiment, the specific transmission mode of the N physical shared channels to be repeatedly transmitted may be determined according to a preset time domain restriction rule, so as to ensure that the time domain span of the repeatedly transmitted physical shared channels is not reached Too long.

For symbol-level or non-slot-level PDSCH / PUSCH transmission, in repeated transmissions, if a symbol that is different from the current transmission channel is encountered, for example, a DL symbol is encountered on a physical uplink shared channel, or a flexible symbol is changed For a symbol that is different from the current transmission channel, it will cause a conflict in the transmission direction. However, there is currently no specific solution on how to resolve the transmission conflict.

In actual transmission, for symbol-level or non-slot (non-slot) level PDSCH / PUSCH transmission (that is, the physical shared channel is based on non-slot scheduling), you may encounter the symbol type in a certain slot. Changes (such as the adjustment of the transmission direction of the flexible symbol or the change of the flexible symbol scheduling method, for example, the change from a semi-static flexible symbol to a dynamically scheduled flexible symbol), resulting in the originally allocated resources in the adjusted time slot not being able to be transmitted Physically share the channel, thereby causing collisions in the transmission direction.

In a specific embodiment of the present disclosure, for the terminal, it is not expected that dynamic scheduling on the network side will cause such conflicts to occur, so for the network side, it can avoid those pre-assigned to physical shared channels during dynamic scheduling symbol. Or the terminal delays the transmission of the conflicting symbol until the continuous available resources can carry the transmission.

However, when the transmission of the configuration authorization causes the above conflict, the specific embodiments of the present disclosure may adopt the following manner to resolve this transmission conflict:

1. Cancel the transmission of the physical shared channel resource of the conflicting symbol on the time slot, or

2. Postpone the remaining physical shared channel to the next symbol sequence that satisfies the condition for transmission.

The above situation usually occurs when there is a time slot format change signaling. If scheduling information or data arrives only after the current slot receives the time slot format change signaling, the sending end can determine the transmission resource according to the signaling instruction. Therefore, from a transmission perspective, in specific embodiments of the present disclosure, the repetition Transmission of N physical shared channels can be described as multi-segment transmission, which includes:

Repeatedly transmit the first M physical shared channels of the N physical shared channels in the first time slot, where M is a positive integer less than N, and in the time domain, any one of the M physical shared channels The transmission resources of the shared channel are continuously distributed in the time domain, that is, the M physical shared channels repeatedly transmitted in the first time slot satisfy the preset transmission rule, which can effectively avoid the transmission direction conflict problem when repeated transmission in the time slot .

When the symbol type in the fifth transmission resource changes, the physical shared channel to be transmitted may be discarded, or the sixth physical transmission resource after the fifth transmission resource may be used to transmit the physical shared channel to be transmitted; wherein, The fifth transmission resource is: continuous transmission resources pre-allocated to the physical shared channel to be transmitted in the second time slot after the first time slot, and the sixth transmission resource is: in the time domain, Transmission resources continuously distributed in one time slot.

For example, the transmission resource allocation of the four physical uplink shared channels PUSCH to be repeatedly transmitted in the first time slot and the second time slot is shown in FIG. 4, where the first PUSCH, the second PUSCH, and the third PUSCH are pre-allocated Symbols 8 to 13 in the first time slot (slot n) are in turn, and the fourth PUSCH is located in

symbols

2 and 3 in the second time slot (slot n + 1). The second symbol in the second time slot (time slot n + 1) changes from the F symbol to the D symbol, then the first 3 PUSCHs among the 4 PUSCHs can be repeatedly transmitted in the first time slot (time slot n), and The fourth PUSCH to be transmitted in the second time slot (time slot n + 1) is discarded, or the fourth PUSCH is delayed to the transmission of the

symbols

3 and 4 in the second time slot (time slot n + 1).

In this way, if the symbol type in the subsequent time slot is changed during repeated transmission, the physical shared channel to be transmitted can be discarded as described in this embodiment, or the physical shared channel to be transmitted can be delayed to continuous Transmission resources distributed in a time slot are transmitted, so that conflicts in the transmission direction can be effectively resolved.

It should be noted that, during the repeated transmission process, the sending-end device and the receiving-end device can also pre-configure the Redundancy Version (RV) corresponding to each physical shared channel that is transmitted.

Specifically, the configuration of the redundant version can be implemented in different ways, as described in detail below.

In one way, a combination of high-level configuration and Downlink Control Information (DCI) indication can be used to indicate the RV version. The high-level pre-configured RV mode can be used. For example, the configuration mode 1 is: {0,2, 3,1}, mode 2 is {0,0,0,0}, mode 3 is {0,3,0,3}, after the higher layer instructs to use one or more of these modes, then use DCI to instruct the terminal to transmit The mode used at the time.

For example, if the higher layer instructs to use the RV versions of these three modes, the signaling shown in Table 1 below can be designed in the DCI to indicate the RV version used during repeated transmission, where different DCI signaling indicates different Transmission mode.

In this way, the terminal can determine the RV version used in each repeated transmission based on the received DCI signaling. For example, when the DCI signaling of "00" is received, it can determine that the RV0 is transmitted during the first transmission and the second time. RV2 is transmitted during transmission, RV3 is transmitted during the third transmission, and RV1 is transmitted during the fourth transmission.

Table 1 DCI signaling indicates the transmission version

In another way, a fixed RV mode can be used, and only DCI is used to indicate the RV version used in the repeated transmission. For example, the DCI can design the signaling shown in Table 2 below to indicate the repeated transmission. The RV version used. In this way, without using RCC signaling, only the DCI indication can be used to determine the RV sequence used in each repeated transmission, thereby reducing transmission overhead.

Table 2 DCI signaling indicates the transmission version

Among them, if the number of transmissions is more or less than the RV version indicated by DCI, the terminal may determine the transmitted RV sequence in a repeated or truncated manner, that is, the terminal may determine the use of each repeated transmission according to the fixed RV mode and the number of transmissions RV sequence. For example, if DCI indicates the use of "00" in Table 2 as the RV sequence used in repeated transmissions, when DCI indicates that the number of repeated transmissions is 8, it may be determined in a repeating manner that each transmission in the 8 transmissions The RV versions adopted are 0, 2, 3, 1, 0, 2, 3, 1, respectively. When DCI indicates that the number of repeated transmissions is 3, a truncated method can be adopted to determine which of the 3 transmissions is adopted respectively. The RV version is 0, 2, 3.

In the embodiment of the present disclosure, the above terminal may be any device with a storage medium, for example: a computer (Computer), a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (personal digital assistant) , PDA), mobile Internet device (Mobile Internet Device, MID) or wearable device (Wearable Device) and other terminal devices.

In the transmission method in this embodiment, when the transmitting end device repeatedly transmits the physical shared channel with the receiving end device, the transmission resource of any physical shared channel can satisfy the rule of continuous distribution in the time domain and located in the same time slot The transmission is performed, so that the mapping position of each physical shared channel repeatedly transmitted to the transmission resource can be determined.

Referring to FIG. 5, FIG. 5 is a flowchart of another transmission method provided by an embodiment of the present disclosure, which is used for a receiver device, and the receiver device is a network-side device or terminal. As shown in FIG. 5, the method includes The following steps:

Step 501: Receive N physical shared channels that are repeatedly transmitted; where N is an integer greater than 1;

It should be noted that this embodiment is an implementation manner of the receiving end device corresponding to the embodiment shown in FIG. 1. For a specific implementation manner, reference may be made to related descriptions in the embodiment shown in FIG. , This embodiment will not repeat them.

Optionally, when the receiving end device is a network side device, before receiving the N physically shared channels that are repeatedly transmitted, the method further includes:

Sending repeated transmission instruction information, where the repeated transmission instruction information includes: a time domain starting position S, a length L of the physical shared channel and the N, and is used for the terminal to determine the N physical shared channels in combination with the slot format indication information Transmission resources in the time domain.

or

In this embodiment, when the receiving end device repeatedly transmits the physical shared channel with the sending end device, the transmission resources of any physical shared channel can be continuously distributed in the time domain and located in the same time slot.
