Description

Transmission method and reception method of uplink control information, device thereof, and communication system

technical field

The embodiments of the present application relate to the technical field of wireless communication.

Background technique

In order to meet the requirement of reliability coverage, New Radio (NR) introduces a variety of uplink control channel formats to deal with different scenarios. In addition, NR introduces a flexible uplink information transmission mechanism to improve system performance.

It should be noted that the above description of the technical background is only for the convenience of clearly and completely describing the technical solutions of the present application and facilitating the understanding of those skilled in the art. It should not be assumed that the above-mentioned technical solutions are known to those skilled in the art simply because these solutions are described in the background section of this application.

SUMMARY OF THE INVENTION

Since NR can support a central emission frequency of up to 52.6 GHz, in high-frequency scenarios, due to the poor diffraction ability of high-frequency signals, it is easy to be affected by blockage. Such channel quality degradation due to occlusion is very unfavorable for low-latency and high-reliability (URLLC) services. This is because the communication delay requirement of the URLLC service is generally less than 3 milliseconds. If the transmission of the uplink control information is affected by the blocking, the delay requirement of the URLLC may not be met.

In order to reduce the impact of occlusion on the sending of uplink control information, a feasible way is to send the uplink control information in a spatial diversity manner. That is to say, on the user equipment (UE) side, the same data can be sent in different time domain uplink transmission opportunities (or called physical uplink control channel repetition, that is, PUCCH repetition), via different airspace paths or via different transmission opportunities and reception point (transmission and reception point, TRP) to reach the base station. In this way, when one path is blocked, other paths can still continue to work, so that the uplink data meets the requirements of low latency and high reliability.

The inventor of the present application found that there is currently no mechanism to support multiplexing of different types of uplink control information (UCI) in the PUCCH repetition. Therefore, it is easy to cause the uplink data to not be sent in time, or the channel state of the downlink channel to be obtained by the base station.

Specifically, the inventor believes that: when the communication system sends the URLLC service, in order to enhance the robustness of the URLLC service, the PUCCH repetition can be used. Each PUCCH repetition corresponds to a different TRP, so that when the channel quality of one TRP is degraded, the uplink control information can still be received by the base station on another TRP. In order to transmit the uplink multiple transmission and reception point (mTRP) PUCCH, the PUCCH of format 0 (format 0) is repeated in the time domain. Due to the high delay requirement of the URLLC service, the HARQ-ACK information is usually sent as early as possible. When the downlink data traffic is very intensive and the delay requirement is very high, the PUCCH used for HARQ-ACK feedback almost fills up all uplink transmission opportunities. According to the existing mechanism, when a repetition occurs on the PUCCH, it is not allowed to multiplex different types of UCIs in the PUCCH where the repetition occurs again. That is to say, the PUCCH repetition can only send HARQ-ACK information, even if the gNB is configured with other types of UCI (for example, Scheduling Request (SR) or Channel State Information (CSI)) in the corresponding time domain resources. Since multiplexing of different UCI types is not supported, these SRs or CSIs cannot be sent either, so that uplink data cannot be sent in time, or the channel state of the downlink channel cannot be obtained by the base station.

In order to at least solve the above problems or similar problems, the embodiments of the present application provide a method for sending uplink control information, a method for receiving the uplink control information, an apparatus therefor, and a communication system. A terminal device sends different types of uplink control information (UCI) corresponding to two or more PUCCHs. ), thus, different types of UCI can be sent in a highly reliable PUCCH resource (eg, mTRP PUCCH) at the same time, taking into account the low latency and robustness of the communication system.

first aspect of the embodiment

The first aspect of the embodiments of the present application relates to a method for sending uplink control information, which is applied to a terminal device, for example, the terminal device 102 .

FIG. 2 is a schematic diagram of a method for sending uplink control information (UCI) according to an embodiment of the first aspect. As shown in Figure 2, the method includes:

In operation 201, the terminal device is instructed to send more than two PUCCHs, wherein each PUCCH corresponds to more than two repetitions, and the two or more PUCCHs correspond to the same starting time unit; and

In operation 202, the terminal device sends UCIs corresponding to the two or more PUCCHs, where the UCIs sent by the terminal device include different types of UCIs.

According to the first aspect of the embodiments of the present application, the terminal device sends different types of uplink control information (UCI) corresponding to two or more PUCCHs, so that the different types of UCIs can be simultaneously used in highly reliable PUCCH resources (for example, mTRP PUCCH ), taking into account the low latency and robustness of the communication system.

In at least one embodiment, the time unit is a time slot (slot) as an example, but the present application is not limited thereto, and the time unit may also be a frame, a subframe, or a sub-slot (sub-slot). Among them, one sub-slot can consist of 2 or 7 symbols.

In at least one embodiment, the terminal device generates the UCI according to the portion of the two or more PUCCHs in the starting time unit.

In at least one embodiment, the terminal device may transmit the UCI using a PUCCH resource corresponding to one of the two or more PUCCHs. Wherein, the PUCCH sequence of the UCI sent by the terminal device and the PUCCH sequence corresponding to one of the two or more PUCCHs adopt different cyclic shifts (sequence cyclic shift).

In at least one embodiment, the physical layer priorities of the two or more PUCCHs are the same.

Hereinafter, the method for sending UCI in FIG. 2 will be described with reference to specific embodiments and comparative examples, and each embodiment or comparative example is collectively referred to as “examples”. In the following embodiments or comparative examples, the terminal device is denoted as UE.

Example 1-1,

Example 1-1 is an embodiment of FIG. 2 in which, in the time domain, more than two PUCCHs overlap in the starting time unit.

FIG. 3 is a schematic diagram of the terminal equipment of Example 1-1 sending UCI.

As shown in FIG. 3 , in this embodiment, the UE receives an instruction to send the PUCCH. Wherein, the indication of sending PUCCH includes:

1. Send an indication of HARQ-ACK feedback, the format of the PUCCH resource used to carry the HARQ-ACK information is PUCCH format 0, and the number of repetitions of PUCCH is 2. The PUCCH is an mTRP PUCCH, that is, HARQ#rep1 and HARQ#rep2 correspond to TRP#1 and TRP#2, respectively. In other words, HARQ#rep1 and HARQ#rep2 respectively use independent spatial relation parameters (spatial relation parameters) or independent power control parameters (power control parameters).

2. Send an SR indication, the format of the PUCCH resource used to carry the SR is PUCCH format 0, and the repetition number of PUCCH is 2. The PUCCH is the mTRP PUCCH, that is, SR#rep1 and SR#rep2 correspond to TRP#1 and TRP#2, respectively. In other words, SR#rep1 and SR#rep2 respectively use independent spatial relation parameters (spatial relation parameters) or independent power control parameters (power control parameters).

The above-mentioned PUCCH resources for carrying HARQ-ACK information and the above-mentioned PUCCH resources for carrying SR overlap in the time domain. More specifically, the starting time slots corresponding to the above-mentioned resources are the same, and they overlap in this time slot. Therefore, the UE can complete UCI multiplexing according to the PUCCH repetition corresponding to the initial time slot, that is, perform UCI multiplexing according to HARQ#rep1 and SR#rep1, and multiplex HARQ-ACK information and SR together. The UE sends the multiplexed UCI (HARQ+SR) using one PUCCH resource, which is the same as the PUCCH resource used by the HARQ (the number of repetitions of the resource is 2). Different from sending the HARQ-ACK information separately, the sequence cyclic shift adopted by this PUCCH resource is different. For example, when only HARQ-ACK information is sent, the corresponding relationship between m _cs and hybrid automatic repeat request value (HARQ value) is as follows (1-bit HARQ, 2-bit HARQ), and the specific meaning of m _cs refers to existing standards.

HARQ-ACK ValueHARQ-ACK Value	00	11
Sequence cyclic shiftSequence cyclic shift	m _CS＝0 _mCS = 0	m _CS＝6 _mCS = 6

HARQ-ACK ValueHARQ-ACK Value	{0,0}{0,0}	{0,1}{0,1}	{1,1}{1,1}	{1,0}{1,0}
Sequence cyclic shiftSequence cyclic shift	m _CS＝0 _mCS = 0	m _CS＝3 _mCS = 3	m _CS＝6 _mCS = 6	m _CS＝9 _mCS = 9

For another example, when HARQ-ACK information is multiplexed with positive SR, the corresponding relationship between m _cs and HARQ value is as follows (1-bit HARQ, 2-bit HARQ), and the specific meaning of m _cs refers to existing standards.

HARQ-ACK ValueHARQ-ACK Value	00	11
Sequence cyclic shiftSequence cyclic shift	m _CS＝3 _mCS = 3	m _CS＝9 _mCS = 9

HARQ-ACK ValueHARQ-ACK Value	{0,0}{0,0}	{0,1}{0,1}	{1,1}{1,1}	{1,0}{1,0}
Sequence cyclic shiftSequence cyclic shift	m _CS＝1 _mCS = 1	m _CS＝4 _mCS = 4	m _CS＝7 _mCS = 7	m _CS＝10 _mCS = 10

According to the method described in this embodiment, the UE can multiplex different types of UCI carried by the repeated PUCCH, so as to avoid the problem of insufficient uplink UCI transmission opportunities. In addition, the initial time slots of these multiplexed PUCCHs are the same. This has the advantage that the UE only needs to consider UCI multiplexing in this initial time slot, and does not need to consider the situation of subsequent time slots, which greatly reduces the UE's Handling complexity. In addition, this method also enables the UE to reuse the existing UCI multiplexing rules for processing PUCCH without repetition, which greatly simplifies the complexity of system design.

In addition, this embodiment is not limited to PUCCH format 0, and the PUCCH format may also be PUCCH format 2 or other types (PUCCH format 1/3/4). In addition, the UCI multiplexing method in this example is not limited to HARQ-ACK information and SR, and may also be multiplexing between other UCI types, such as CSI and HARQ-ACK information.

Example 1-2,

Example 1-2 is a comparative example to Example 1-1.

FIG. 4 is a schematic diagram of the terminal equipment of Example 1-2 sending UCI.

As shown in FIG. 4 , in this embodiment, the UE receives an instruction to send the PUCCH. Wherein, the indication of sending PUCCH includes:

Send an indication of HARQ-ACK feedback, the format of the PUCCH resource used to carry the HARQ-ACK information is PUCCH format 0, and the number of repetitions of PUCCH is 2. The PUCCH is an mTRP PUCCH, that is, HARQ#rep1 and HARQ#rep2 correspond to TRP#1 and TRP#2, respectively. In other words, HARQ#rep1 and HARQ#rep2 respectively use independent spatial relation parameters (spatial relation parameters) or independent power control parameters (power control parameters).

The indication of the SR is sent, the format of the PUCCH resource used to carry the SR is PUCCH format 0, and the number of repetitions of the PUCCH is 2. The PUCCH is the mTRP PUCCH, that is, SR#rep1 and SR#rep2 correspond to TRP#1 and TRP#2, respectively. In other words, SR#rep1 and SR#rep2 respectively use independent spatial relation parameters (spatial relation parameters) or independent power control parameters (power control parameters).

The above-mentioned PUCCH resources used to carry HARQ-ACK information and the above-mentioned PUCCH resources used to carry SR overlap in the time domain. #rep1) overlaps with the second repetition of HARQ-ACK (HARQ #rep2). Since the starting time slots of the two PUCCHs are different, the UE does not perform UCI multiplexing but sends the corresponding UCI according to the UCI priority of each time slot. That is to say, in slot #1, HARQ-ACK #rep1 is sent; in slot #2, since the UCI corresponding to the HARQ-ACK information has a high priority, when the HARQ-ACK information overlaps with the SR, the UE sends the HARQ -ACK information (HARQ#rep2) without sending SR (SR#rep1); since UCI multiplexing is not performed, in slot#3, SR#rep2 is sent.

In addition, this example is not limited to PUCCH format 0, and the PUCCH format may also be PUCCH format 2 or other types (PUCCH format 1/3/4). In addition, the UCI multiplexing method in this example is not limited to HARQ-ACK information and SR, and may also be multiplexing between other UCI types, such as CSI and HARQ-ACK information.

Example 2-1,

Example 2-1 is an embodiment of FIG. 2 . In Example 2-1, in the time domain, the repetition times of the two or more PUCCHs are the same.

FIG. 5 is a schematic diagram of the terminal equipment of Example 2-1 sending UCI.

As shown in FIG. 5 , in this embodiment, the UE receives an instruction to send the PUCCH. Wherein, the indication of sending PUCCH includes:

1. Send an indication of HARQ-ACK feedback, the format of the PUCCH resource used to carry the HARQ-ACK information is PUCCH format 0, and the number of repetitions of PUCCH is 4. The PUCCH is an mTRP PUCCH, that is, HARQ#rep1/HARQ#rep3 and HARQ#rep2/HARQ#rep4 correspond to TRP#1 and TRP#2, respectively. In other words, HARQ#rep1/HARQ#rep3 and HARQ#rep2/HARQ#rep4 use independent spatial relation parameters or independent power control parameters, respectively.

2. The indication of the SR is sent, the format of the PUCCH resource used to carry the SR is PUCCH format 0, and the number of repetitions of the PUCCH is 4. The PUCCH is the mTRP PUCCH, that is, SR#rep1/SR#rep3 and SR#rep2/SR#rep4 correspond to TRP#1 and TRP#2, respectively. In other words, SR#rep1/SR#rep3 and SR#rep2/SR#rep4 use independent spatial relation parameters or independent power control parameters, respectively.

The above-mentioned PUCCH resources for carrying HARQ-ACK information and the above-mentioned PUCCH resources for carrying SR overlap in the time domain. overlapping time slots. Therefore, the UE can complete UCI multiplexing according to the PUCCH repetition corresponding to the initial time slot, that is, perform UCI multiplexing according to HARQ-#rep1 and SR#rep1, and multiplex HARQ-ACK information and SR together. The UE sends the multiplexed UCI (HARQ+SR) using one PUCCH resource, which is the same as the PUCCH resource used by the HARQ (for example, the number of repetitions of the resource is 4). Different from sending the HARQ-ACK information separately, the sequence cyclic shift adopted by this PUCCH resource is different. For example, when only HARQ-ACK information is sent (when SR is negative SR), the corresponding relationship between m _cs and HARQ value is as follows (1-bit HARQ, 2-bit HARQ), and the specific meaning of m _cs refers to existing standards.

For another example, when HARQ-ACK information is multiplexed with positive SR, the corresponding relationship between mcs and HARQ value is as follows (1-bit HARQ, 2-bit HARQ), and the specific meaning of mcs refers to existing standards.

According to the method described in this example, the UE can multiplex different types of UCI carried by the duplicated PUCCH to avoid the problem of insufficient uplink UCI transmission opportunities. In addition, the initial time slots of these multiplexed PUCCHs are the same. This has the advantage that the UE only needs to consider UCI multiplexing in this initial time slot, and does not need to consider the situation of subsequent time slots, which greatly reduces the UE's Handling complexity. This method also enables the UE to reuse the existing UCI multiplexing rules for processing PUCCH without repetition, which greatly simplifies the complexity of system design. In addition, this method performs UCI multiplexing on PUCCHs with the same number of repetitions. Generally speaking, the number of repetitions of PUCCH is the same, which means that the coverage requirements of the UCI carried by the PUCCH are close. Therefore, the advantage of this is that the PUCCH transmissions with the same coverage requirements are combined into one transmission, which saves the overhead of uplink transmission. At the same time, multiplexing of PUCCHs with different coverage requirements (multiplexing of UCIs in PUCCHs with different repetition times) is avoided.

Example 2-2,

Example 2-2 is a comparative example to Example 2-1.

FIG. 6 is a schematic diagram of sending UCI by the terminal device of Example 2-2.

As shown in FIG. 6 , in an example, the UE receives an instruction to send a PUCCH. Wherein, the indication of sending PUCCH includes:

Send an indication of HARQ-ACK feedback, the format of the PUCCH resource used to carry the HARQ-ACK information is PUCCH format 0, and the number of repetitions of PUCCH is 4. The PUCCH is an mTRP PUCCH, that is, HARQ#rep1/HARQ#rep3 and HARQ#rep2/HARQ#rep4 correspond to TRP#1 and TRP#2, respectively. In other words, HARQ#rep1/HARQ#rep3 and HARQ#rep2/HARQ#rep4 use independent spatial relation parameters or independent power control parameters, respectively. This TRP/beam mapping method is also called cyclic mapping.

The above-mentioned PUCCH resources for carrying HARQ-ACK information and the above-mentioned PUCCH resources for carrying SR overlap in the time domain. rep1) overlaps with the first repetition of HARQ-ACK (HARQ#rep1); the second repetition of SR (SR#rep2) overlaps with the second repetition of HARQ-ACK (HARQ#rep2). However, since the repetition times of the two PUCCHs are different, the UE does not perform UCI multiplexing but transmits the corresponding UCI according to the UCI priority of each time slot. That is to say, in slot#1 and slot#2, since the UCI corresponding to the HARQ-ACK information has a higher priority than the SR, the UE sends HARQ-ACK#rep1 and HARQ-ACK#rep2 in these two slots respectively ; In slot#3 and slot#4, the UE continues to send HARQ#rep3 and HARQ#rep4.

In this example, the reason why UCIs are not multiplexed is that the repetition times of the two PUCCHs are different, which means their coverage/delay requirements are different. Latency increases. In this example, since the HARQ-ACK information is repeated more times than the SR, after multiplexing, the SR information may be sent later than the predetermined time, exceeding its valid time, making the sending of the SR meaningless).

Example 2-3,

Example 2-3 is an embodiment of FIG. 2 of the present application. In Example 2-3, the repetition times of the two or more PUCCH resources are different, and the uplink control information sent by at least one of the two or more PUCCH resources corresponds to the low physical layer priority and/or the first number reported by the terminal device. an ability. The low physical layer priority means that the physical layer priority index is 0, that is, the priority index is 0; for the description of the physical layer priority of the PUCCH or the priority of the PUCCH, reference may be made to the related art. The first capability means that the terminal device can multiplex different types of UCIs in the PUCCH with different repetition times.

In addition, in Example 2-3, the number of repetitions of the PUCCH resource for transmitting UCI may be the same as the number of repetitions of the PUCCH resource with the largest number of repetitions among the PUCCH resources corresponding to the two or more PUCCHs, or the repetition of the PUCCH resource for transmitting UCI The number of times may be the same as the number of repetitions of the PUCCH resource with a smaller number of repetitions among the PUCCH resources corresponding to the two or more PUCCHs.

FIG. 7 is a schematic diagram of the terminal equipment of Example 2-3 sending UCI.

In this example, the UE receives an indication to send the PUCCH. Among them, including:

Send an indication of HARQ-ACK feedback, the format of the PUCCH resource used to carry the HARQ-ACK information is PUCCH format 0, and the number of repetitions of PUCCH is 4. The PUCCH is the mTRP PUCCH, that is, HARQ#rep1/HARQ#rep3 and HARQ#rep2/HARQ#rep4 correspond to TRP#1 and TRP#2, respectively. In other words, HARQ#rep1/HARQ#rep3 and HARQ#rep2/HARQ#rep4 use independent spatial relation parameters or independent power control parameters, respectively. This TRP/beam mapping method is also called cyclic mapping. In addition, the HARQ-ACK information corresponds to a low physical layer priority (or the physical layer priority index is 0).

The indication of the SR is sent, the format of the PUCCH resource used to carry the SR is PUCCH format 0, and the number of repetitions of the PUCCH is 2. The PUCCH is the mTRP PUCCH, that is, SR#rep1 and SR#rep2 correspond to TRP#1 and TRP#2, respectively. In other words, SR#rep1 and SR#rep2 respectively use independent spatial relation parameters (spatial relation parameters) or independent power control parameters (power control parameters). In addition, SR corresponds to a low physical layer priority (or the physical layer priority index is 0).

The above-mentioned PUCCH resources for carrying HARQ-ACK information and the above-mentioned PUCCH resources for carrying SR overlap in the time domain. rep1) overlaps with the first repetition of HARQ-ACK (HARQ#rep1). As shown in Figure 7, this is another approach to a scenario similar to Example 2-2. Different from Example 2-2, since the SR corresponds to a low physical layer priority, which means that the SR is not sensitive to delay, the UE can multiplex the HARQ-ACK information with the SR. The UE uses one PUCCH resource to send the multiplexed UCI (HARQ+SR), which is the same as the PUCCH resource used by the HARQ (the number of repetitions of this resource is 4, in this example, the repetition of the PUCCH resource with more repetitions is used times, as the number of repetitions corresponding to the PUCCH resource carrying the multiplexed UCI). Different from sending the HARQ-ACK information separately, the sequence cyclic shift adopted by this PUCCH resource is different. For example, when only HARQ-ACK information is sent (when SR is negative SR), the corresponding relationship between m _cs and HARQ value is as follows (1-bit HARQ, 2-bit HARQ), and the specific meaning of m _cs refers to existing standards.

Through Example 2-3, the transmission opportunity of uplink UCI that can only transmit HARQ-ACK information originally is increased to be able to transmit HARQ-ACK information and SR at the same time. Therefore, the method increases the transmission opportunity of UCI, so that different types of UCI can be transmitted through PUCCH with repetition, which improves the flexibility of the system. In addition, the method can also decide whether to multiplex different types of UCI in the PUCCH repetition according to the physical layer priority corresponding to the UCI carried by the PUCCH, which improves the reliability of UCI transmission.

Example 3-1,

Example 3-1 is an embodiment of FIG. 2 of the present application. In Example 3-1, the repetition periods of PUCCH transmission corresponding to the two or more PUCCHs are the same.

FIG. 8 is a schematic diagram of the terminal equipment of Example 3-1 sending UCI.

As shown in FIG. 8 , in this embodiment, the UE receives an instruction to send the PUCCH. Wherein, the indication of sending PUCCH includes:

Send the indication of HARQ-ACK feedback, the format of the PUCCH resource used to carry the HARQ-ACK information is PUCCH format 0, the number of repetitions of PUCCH is 2, and the repetition method is sub-slot based, that is to say, its repetition period is A sub-slot is a unit, and specifically, its repetition period is 7 symbols. The PUCCH is an mTRP PUCCH, that is, HARQ#rep1 and HARQ#rep2 correspond to TRP#1 and TRP#2, respectively. In other words, HARQ#rep1 and HARQ#rep2 respectively use independent spatial relation parameters (spatial relation parameters) or independent power control parameters (power control parameters).

To send an SR indication, the format of the PUCCH resource used to carry the SR is PUCCH format 0, the number of PUCCH repetitions is 2, and the repetition mode is slot based, that is to say, the repetition period is based on time slots. Say, its repetition period is 7 symbols. The PUCCH is the mTRP PUCCH, that is, SR#rep1 and SR#rep2 correspond to TRP#1 and TRP#2, respectively. In other words, SR#rep1 and SR#rep2 use independent spatial relation parameters or independent power control parameters, respectively.

The above-mentioned PUCCH resources for carrying HARQ-ACK information and the above-mentioned PUCCH resources for carrying SR overlap in the time domain. More specifically, the start time slots corresponding to the above-mentioned resources are the same, and their repetition periods are the same. Therefore, the UE can complete UCI multiplexing according to the PUCCH repetition corresponding to the initial time slot, that is, perform UCI multiplexing according to HARQ#rep1 and SR#rep1, and multiplex HARQ-ACK information and SR together. The UE sends the multiplexed UCI (HARQ+SR) using one PUCCH resource, which is the same as the PUCCH resource used by the HARQ (the number of repetitions of the resource is 2). Different from sending the HARQ-ACK information separately, the sequence cyclic shift adopted by this PUCCH resource is different. For example, when only HARQ-ACK information is sent, the corresponding relationship between m _cs and hybrid automatic repeat request value (HARQ value) is as follows (1-bit HARQ, 2-bit HARQ), and the specific meaning of m _cs refers to existing standards.

According to the method described in this embodiment, the UE can multiplex different types of UCI carried by the repeated PUCCH, so as to avoid the problem of insufficient uplink UCI transmission opportunities. In addition, the initial time slots of these multiplexed PUCCHs are the same. This has the advantage that the UE only needs to consider UCI multiplexing in this initial time slot, and does not need to consider the situation of subsequent time slots, which greatly reduces the UE's Handling complexity. This method also enables the UE to reuse the existing UCI multiplexing rules for processing PUCCH without repetition, which greatly simplifies the complexity of system design. In addition, in this scheme, the UCIs corresponding to the PUCCH repetitions with the same repetition period are multiplexed. The advantage of this is that the repetition periods of the PUCCH repetitions are the same, which means that their corresponding UCI delay requirements are similar. Therefore, these different types of UCIs The multiplexing will not make some types of UCI exceed the upper limit of the delay, preventing the system from being unable to meet the delay requirements of communication.

Example 3-2,

Example 3-2 is a comparative example to Example 3-1.

FIG. 9 is a schematic diagram of the terminal equipment of Example 3-2 sending UCI.

To send an SR indication, the format of the PUCCH resource used to carry the SR is PUCCH format 0, the number of PUCCH repetitions is 2, and the repetition mode is slot based, that is to say, the repetition period is based on time slots. Say, its repetition period is 1 slot (14 symbols). The PUCCH is the mTRP PUCCH, that is, SR#rep1 and SR#rep2 correspond to TRP#1 and TRP#2, respectively. In other words, SR#rep1 and SR#rep2 respectively use independent spatial relation parameters (spatial relation parameters) or independent power control parameters (power control parameters).

The above-mentioned PUCCH resources for carrying HARQ-ACK information and the above-mentioned PUCCH resources for carrying SR overlap in the time domain. rep1) overlaps with the second repetition of HARQ-ACK (HARQ#rep2); however, due to the different repetition periods, the second repetition of SR (SR#rep2) does not overlap with the second repetition of HARQ-ACK (HARQ#rep2) overlapping. Since the repetition periods of the two PUCCHs are different (or their repetition modes are different slot-based vs. subslot-based), the UE does not perform UCI multiplexing but sends the corresponding UCI according to the UCI priority of each subslot. That is to say, in subslot #1, since the UCI corresponding to the HARQ-ACK information has a high priority, when the HARQ-ACK information overlaps with the SR, the UE sends the HARQ-ACK information (HARQ#rep1) without sending the SR ( SR#rep1); in subslot#2, the UE sends HARQ-ACK#rep2; since UCI multiplexing is not performed, the UE sends SR#rep2 in subslot#3 or slot#2.

In Example 3-2, the reason why UCIs are not multiplexed is that the repetition periods of the two PUCCHs are different, which means that their end times or delay requirements are different. If the UCI they carry is very delay sensitive, it may result in increased transmission delay. Also, if they end at a different time, it means that one of the types of UCI is sent earlier. In an example, since the end time of the HARQ-ACK information is earlier than that of the SR, multiplexing the SR with the HARQ-ACK information means that the SR information needs to be generated and sent earlier, which increases the processing complexity of the UE.

Example 3-3,

Example 3-3 is an embodiment of FIG. 2 of the present application.

In Example 3-3, the repetition periods of PUCCH transmission corresponding to the two or more PUCCHs are different, and the uplink control information corresponding to at least one of the two or more PUCCHs corresponds to the low physical layer priority and/or the terminal The second capability reported by the device. The low physical layer priority means that the physical layer priority index is 0, that is, the priority index is 0; for the description of the physical layer priority of the PUCCH or the priority of the PUCCH, reference may be made to the related art. The second capability means that the terminal device can multiplex different types of UCIs in PUCCH corresponding to different repetition periods of PUCCH resources.

In Example 3-3, the repetition period of the PUCCH resource for sending UCI is the same as the repetition period of the PUCCH resource with the longer repetition period among the PUCCH resources corresponding to the two or more PUCCHs; or, the repetition period of the PUCCH resource for sending UCI The repetition period of the PUCCH resource with a shorter repetition period among the PUCCH resources corresponding to the two or more PUCCHs is the same.

FIG. 10 is a schematic diagram of the terminal equipment of Example 3-3 sending UCI.

As shown in Figure 10, Example 3-3 is another processing method of the same scenario as Example 3-2. In this processing manner, due to the high processing capability of hardware (for example, the multiplexing of HARQ and SR can be completed quickly), HARQ-ACK information can be multiplexed with SR. The UE sends the multiplexed UCI (HARQ+SR) using one PUCCH resource, which is the same as the PUCCH resource used by the HARQ (the number of repetitions of the resource is 2). Different from sending the HARQ-ACK information separately, the sequence cyclic shift adopted by this PUCCH resource is different. For example, when only HARQ-ACK information is sent (when SR is negative SR), the corresponding relationship between m _cs and HARQ value is as follows (1-bit HARQ, 2-bit HARQ), and the specific meaning of m _cs refers to existing standards.

The effect of Example 3-3 is that the SR that can only be sent in a single TRP can be sent through multiple TRPs together with the HARQ-ACK information after UCI multiplexing. Thus, the robustness of the SR signal is increased, thereby improving the reliability of the communication system.

Example 4-1,

Example 4-1 is an example of FIG. 2 . In Example 4-1, the beam patterns corresponding to two or more PUCCHs are the same.

The beam patterns corresponding to the two or more PUCCHs are the same, including:

The beam patterns of the PUCCH resources used to transmit the two or more PUCCHs are all corresponding to a single transmission and reception point (sTRP, single transmission and reception point), or are corresponding to multiple transmission and reception points (mTRP, multiple transmission and reception point) reception point); or

The beam patterns used to transmit the PUCCH resources of the two or more PUCCHs are all corresponding to multiple transmission and reception points (mTRP, multiple transmission and reception points), and the beam patterns corresponding to the two or more PUCCHs are all cyclic (cyclic) or sequential (sequentical); or

The beam patterns used to transmit the PUCCH resources of the two or more PUCCHs all correspond to multiple transmission and reception points (mTRP, multiple transmission and reception points), and the beam patterns corresponding to the two or more PUCCHs have the same TRP Sequence (or, the beam patterns corresponding to the two or more PUCCHs have the same starting TRP; or, the power control parameters or spatial relationship parameters used by the beam patterns corresponding to the two or more PUCCHs are in the same order; or , the initial power control parameters or spatial relationship parameters used by the beam patterns corresponding to the two or more PUCCHs are the same).

The single transmission and reception point means that the PUCCH resource corresponds to a set of power control parameters; or, the PUCCH resource corresponds to a set of spatial relationship parameters. Multiple transmission and reception points means that the PUCCH resources correspond to at least two sets of power control parameters; or, the PUCCH resources correspond to at least two sets of spatial relationship parameters.

FIG. 11 is a schematic diagram of the terminal equipment of Example 4-1 sending UCI.

As shown in FIG. 11 , the UE receives an instruction to send the PUCCH. Among them, including:

The indication of the SR is sent, the format of the PUCCH resource used to carry the SR is PUCCH format 0, and the number of repetitions of the PUCCH is 4. The PUCCH is the mTRP PUCCH, that is, SR#rep1/SR#rep3 and SR#rep2/SR#rep4 correspond to TRP#1 and TRP#2, respectively. In other words, SR#rep1/SR#rep3 and SR#rep2/SR#rep4 use independent spatial relation parameters or independent power control parameters, respectively. This TRP/beam mapping method is also called cyclic mapping.

The above-mentioned PUCCH resources for carrying HARQ-ACK information and the above-mentioned PUCCH resources for carrying SR overlap in the time domain. More specifically, the above-mentioned resources correspond to the same initial time slot, the same number of repetitions, and their beam patterns The same (or in other words, the TRP corresponding to each time slot is the same). Therefore, the UE can complete UCI multiplexing according to the PUCCH repetition corresponding to the initial time slot, that is, perform UCI multiplexing according to HARQ-#rep1 and SR#rep1, and multiplex HARQ-ACK information and SR together. The UE sends the multiplexed UCI (HARQ+SR) using one PUCCH resource, which is the same as the PUCCH resource used by the HARQ (the number of repetitions of the resource is 4). Different from sending the HARQ-ACK information separately, the sequence cyclic shift adopted by this PUCCH resource is different. For example, when only HARQ-ACK information is sent (when SR is negative SR), the corresponding relationship between m _cs and HARQ value is as follows (1-bit HARQ, 2-bit HARQ), and the specific meaning of m _cs refers to existing standards.

For another example, when HARQ-ACK information is multiplexed with positive SR, the corresponding relationship between mcs and HARQ value is as follows (1-bit HARQ, 2-bit HARQ), and the specific meaning of _mcs refers to existing standards.

According to the method described in this example, the UE can multiplex different types of UCI carried by the duplicated PUCCH to avoid the problem of insufficient uplink UCI transmission opportunities. In addition, the initial time slots of these multiplexed PUCCHs are the same. This has the advantage that the UE only needs to consider UCI multiplexing in this initial time slot, and does not need to consider the situation of subsequent time slots, which greatly reduces the UE's Handling complexity. This method also enables the UE to reuse the existing UCI multiplexing rules for processing PUCCH without repetition, which greatly simplifies the complexity of system design. In addition, this method performs UCI multiplexing on the PUCCH with the same beam pattern. Generally speaking, the beam patterns of the PUCCHs are the same, which means that the UCIs carried by these PUCCHs have similar coverage requirements; therefore, the advantage of this is that the PUCCHs with the same coverage requirements are combined into one transmission, which saves the overhead of uplink transmission. At the same time, reliability degradation caused by multiplexing of PUCCHs with different coverage requirements is avoided.

Example 4-2,

Example 4-2 is a comparative example to Example 4-1. It is used to describe the case where the beam patterns (beam patterns) corresponding to two or more PUCCHs are different.

FIG. 12 is a schematic diagram of the terminal equipment of Example 4-2 sending UCI.

The indication of the SR is sent, the format of the PUCCH resource used to carry the SR is PUCCH format 0, and the number of repetitions of the PUCCH is 4. The PUCCH is the sTRP PUCCH, that is, all repetitions of the SR correspond to TRP#1. In other words, all repetitions of the SR correspond to the same spatial relation parameters (spatial relation parameters) or independent power control parameters (power control parameters).

The above-mentioned PUCCH resources for carrying HARQ-ACK information and the above-mentioned PUCCH resources for carrying SR overlap in the time domain. Different (in slot#2 and slot#4, the two PUCCHs correspond to TRP#1 and TRP#2 respectively). In order to avoid multiplexing the UCIs carried by PUCCHs with different coverage requirements, in this example, the UE only sends the PUCCH resources corresponding to the HARQ-ACK (the priority of the HARQ-ACK is higher than that of the SR), and the SR is not sent. .

Example 4-3,

Example 4-3 is a comparative example to Example 4-1. It is used to describe the case where the beam patterns (beam patterns) corresponding to two or more PUCCHs are different.

FIG. 13 is a schematic diagram of the terminal equipment of Example 4-3 sending UCI.

The indication of the SR is sent, the format of the PUCCH resource used to carry the SR is PUCCH format 0, and the number of repetitions of the PUCCH is 4. The PUCCH is the mTRP PUCCH, that is, SR#rep1/SR#rep2 and SR#rep3/SR#rep4 correspond to TRP#1 and TRP#2, respectively. In other words, SR#rep1/SR#rep2 and SR#rep3/SR#rep4 use independent spatial relation parameters or independent power control parameters, respectively. This TRP/beam mapping method is also called sequential mapping.

The above-mentioned PUCCH resources for carrying HARQ-ACK information and the above-mentioned PUCCH resources for carrying SR overlap in the time domain. Different (in slot#2 and slot#3, the two PUCCHs correspond to TRP#1 and TRP#2 respectively). In order to avoid multiplexing the UCIs carried by PUCCHs with different coverage requirements, in this example, the UE only sends the PUCCH resources corresponding to the HARQ-ACK (the priority of the HARQ-ACK is higher than that of the SR), and the SR is not sent. .

Example 4-4,

Example 4-4 is a comparative example to Example 4-1. It is used to describe the case where the beam patterns (beam patterns) corresponding to two or more PUCCHs are different.

FIG. 14 is a schematic diagram of the terminal equipment of Example 4-4 sending UCI.

The indication of the SR is sent, the format of the PUCCH resource used to carry the SR is PUCCH format 0, and the number of repetitions of the PUCCH is 4. The PUCCH is the mTRP PUCCH, that is, SR#rep2/SR#rep4 and SR#rep1/SR#rep3 correspond to TRP#1 and TRP#2, respectively. In other words, SR#rep2/SR#rep4 and SR#rep1/SR#rep3 use independent spatial relation parameters or independent power control parameters, respectively. This TRP/beam mapping method is also called cyclic mapping. It should be noted that, different from case 4-1, the order of TRPs corresponding to SRs has changed (TRP#2 is in the front and TRP#1 is in the back).

The above-mentioned PUCCH resources for carrying HARQ-ACK information and the above-mentioned PUCCH resources for carrying SR overlap in the time domain. Different (in slot#1, slot#2, slot#3 and slot#4, the two PUCCHs correspond to TRP#1 and TRP#2 respectively). In order to avoid multiplexing the UCIs carried by PUCCHs with different coverage requirements, in this example, the UE only sends the PUCCH resources corresponding to the HARQ-ACK (the priority of the HARQ-ACK is higher than that of the SR), and the SR is not sent. .

Example 5,

Example 5 is one embodiment of the method of FIG. 2 . In Example 5, the number of the two or more PUCCHs is, for example, three.

FIG. 15 is a schematic diagram of the terminal equipment of Example 5 sending UCI.

As shown in Figure 15, the UE receives an instruction to send the PUCCH. Among them, including:

Send an indication of HARQ-ACK feedback, the format of the PUCCH resource used to carry the HARQ-ACK information is PUCCH format 2, and the number of repetitions of PUCCH is 2. The PUCCH is an mTRP PUCCH, that is, HARQ#rep1 and HARQ#rep2 correspond to TRP#1 and TRP#2, respectively. In other words, HARQ#rep1 and HARQ#rep2 respectively use independent spatial relation parameters (spatial relation parameters) or independent power control parameters (power control parameters).

Send an indication of CSI feedback, the format of the PUCCH resource used to carry the CSI is PUCCH format 2, and the repetition number of PUCCH is 2. The PUCCH is the mTRP PUCCH, that is, CSI#rep1 and CSI#rep2 correspond to TRP#1 and TRP#2, respectively. In other words, CSI#rep1 and CSI#rep2 respectively use independent spatial relation parameters (spatial relation parameters) or independent power control parameters (power control parameters).

The above-mentioned PUCCH resource for carrying HARQ-ACK information, the above-mentioned PUCCH resource for carrying CSI feedback and the above-mentioned PUCCH resource for carrying SR have the same initial time slot, and they overlap in this time slot (in this example, They overlap in the initial time slot, and they may not overlap, which is not a limitation in this example). Therefore, the UE can complete UCI multiplexing according to the PUCCH repetition corresponding to the initial time slot, that is, according to HARQ-#rep1, CSI#rep1 and SR#rep1, perform UCI multiplexing, and feed back the HARQ-ACK information and CSI. Multiplexed with SR. The UE sends the multiplexed UCI (HARQ+CSI+SR) using one PUCCH resource, which is the same as the PUCCH resource used by the HARQ (the number of repetitions of the resource is 2).

According to the method described in this example, the UE can multiplex different types of UCI carried by the duplicated PUCCH to avoid the problem of insufficient uplink UCI transmission opportunities. In addition, the initial time slots of these multiplexed PUCCHs are the same. This has the advantage that the UE only needs to consider UCI multiplexing in this initial time slot, and does not need to consider the situation of subsequent time slots, which greatly reduces the UE's Handling complexity. In addition, this method also enables the UE to reuse (reuse) the existing UCI multiplexing rules for processing PUCCH without repetition in the initial time slot, which greatly simplifies the complexity of system design.

In addition, this example is not limited to PUCCH format 0, and the PUCCH format may also be PUCCH format 2 or other types (PUCCH format 1/3/4). In addition, the multiplexing method of UCI in this example is not limited to HARQ-ACK information, SR and CSI, and may be a combination of two of these three types of UCI.
