Detailed ways

Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the application as detailed in the appended claims.

The communication systems and business scenarios described in the embodiments of this application are intended to more clearly illustrate the technical solutions of the embodiments of this application, and do not constitute a limitation to the technical solutions provided in the embodiments of this application. Those of ordinary skill in the art will know that with the communication system With the evolution of and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

FIG. 1 shows a block diagram of a communication system provided by an exemplary embodiment of the present application. The communication system may include: an access network 12 and a terminal 13.

The access network 12 includes several access network devices 120. The access network device 120 may be a base station, which is a device deployed in an access network to provide a wireless communication function for a terminal. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, and so on. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in LTE systems, they are called eNodeB or eNB; in 5G NR-U systems, they are called gNodeB or gNB. . As communication technology evolves, the description of "base station" may change. For convenience, in the embodiments of the present application, the above-mentioned devices providing wireless communication functions for the terminal 13 are collectively referred to as access network equipment.

The terminal 13 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of User Equipment (UE), mobile stations ( Mobile Station, MS), terminal (terminal device), etc. For ease of description, the devices mentioned above are collectively referred to as terminals. The access network device 120 and the terminal 13 communicate with each other through a certain air interface technology, such as a Uu interface.

In NR, the flexibility of PUCCH structure design results in their start symbol and end symbol not necessarily aligned. In order to ensure that the terminal has enough processing time to multiplex the UCI information domain data information, the PUCCH and PUCCH must meet fixed timing requirements before multiplexing can be performed, otherwise, the terminal will reserve one PUCCH.

The timing requirements for multiplexing between PUCCH and PDSCH are as follows, as shown in Figure 2:

1. The time difference T1 from the first OFDM symbol of the earliest transmitted channel of the PUCCH with time domain overlap to the last OFDM symbol of the scheduled PDSCH (downlink scheduling grant in Figure 2) of the DCI scheduling HARQ-ACK is greater than N ₁ +d _1,1 +d _1,2 +1 OFDM symbols. Among them, N1 is the PDSCH processing capability reported by the terminal.

2. The time difference T2 from the first OFDM symbol of the earliest transmitted channel of the PUCCH overlapping in the time domain to the last OFDM symbol of the DCI scheduling HARQ-ACK is greater than N ₂ +d _2,1 +1 symbols. Among them, N2 is the PDSCH processing time reported by the terminal.

Among them, μ corresponds to one of (μ _PDCCH , μ _PDSCH , μ _UL ), and the largest T _{PROC, 1 is obtained} . Where μ _PDCCH corresponds to the subcarrier interval of the PDCCH scheduling PDSCH, μ _PDSCH corresponds to the subcarrier interval of the scheduled PDSCH, and μ _UL corresponds to the subcarrier interval of the uplink channel for transmitting HARQ-ACK, and κ is [4, TS 38.211] is defined in subclause 4.41.

If HARQ-ACK is sent on PUCCH, d _1,1 =0.

If the PDSCH is the mapping type A given in the subclause 7.4.1.1 of [4, TS 38.211], and the last symbol of the PDSCH is located on the i-th symbol of the time slot where the time slot i is less than 7, then d _1.2 = 7 .

For UE processing capability 1: If the PDSCH is of mapping type B, and: if the number of allocated PDSCH symbols is 4, then d _1.2 = 3; if the number of allocated PDSCH symbols is 2, then d _1.2 = 3+d, where d is the number of overlapping symbols of scheduled PDCCH and scheduled PDSCH. For UE processing capability 2: if the PDSCH is of mapping type B, if the number of allocated PDSCH symbols is 2 or 4, then d _1.2 is the number of overlapping symbols for scheduling PDCCH and scheduled PDSCH.

Terminal processing capability

After receiving the downlink scheduling information carried in the DCI format 1_0 or 1_1, the terminal will receive the corresponding PDSCH in the corresponding time slot, and send feedback HARQ-ACK information to the base station. The time when the UE starts to send HARQ-ACK is later than T _proc after the end of the last symbol carrying the PDSCH _,1 =[(N ₁ +d _1,1 +d _1,2 )(2048+144)·k2 ^-u ]·T _C time.

If this requirement is not met, the terminal will not send HARQ-ACK. Among them, N1 has different values according to the processing capability of the UE. NR supports two UE processing capabilities, namely UE processing capability 1 and UE processing capability 2. The values of N1 under the two UE processing capabilities are shown in Tables 1.1 and 1.2.

Table 1.1: PDSCH processing capacity 1 PDSCH processing time

Table 1.2: PDSCH processing capacity 2 PDSCH processing time

The earliest transmission time for the terminal to transmit the uplink PDSCH (including DMRS) is later than T _proc after the end of the last symbol of the PUCCH carrying PDSCH scheduling information _{, 2} = [(N ₂ +d _1,1 +d _1,2 )(2048 +144)·k2 ^-u ]·T _C time, where N2 has different values according to the processing capability of the UE. NR supports two UE processing capabilities, namely UE processing capability 1 and UE processing capability 2. The values of N2 under the two processing capabilities are shown in Tables 1.3 and 1.4.

PUCCH-ACK resource determination process

The terminal obtains N PUCCH-ACK resources {PUCCH resource 0, PUCCH resource 1, PUCCH resource 2, PUCCH resource N-1} through semi-static signaling, and N>=1. These PUCCH resources are grouped into at least two groups according to capacity (number of bits carrying UCI), such as {PUCCH resource set 0, PUCCH resource set 1, PUCCH resource set 2, PUCCH resource set 3}. Among them, the number of UCI bits that can be carried by PUCCH resources in PUCCH resource set 0 is less than or equal to 2; the number of UCI bits that can be carried by PUCCH resources in PUCCH resource set 1 is greater than 2 and less than or equal to X1; the number of UCI bits that can be carried by PUCCH resources in PUCCH resource set 2 The number of UCI bits is greater than X1 and less than or equal to X2; the number of UCI bits that can be carried by PUCCH resources in PUCCH resource set 3 is greater than X2 and less than or equal to X3; X1, X2, and X3 are configured by the network.

The terminal selects one PUCCH resource from the aforementioned PUCCH resource set to send UCI according to the PUCCH resource indicator in the downlink scheduling grant (DL grant) and the number of UCI bits.

First, the terminal selects PUCCH resource set i according to the number of UCI bits Y, where Y is within the capacity range of PUCCH resource set i. Second, the terminal selects a PUCCH resource from the PUCCH resource set i according to the PUCCH resource index indication.

In NR systems (such as Ultra-Reliable and Low Latency Communications, URLLC), the terminal has different UE processing capabilities for different types of data, that is, the terminal has at least two UE processing capabilities at the same time within a period of time . Lead to at least the following two technical problems:

Question 1: At least based on which UE processing capability to calculate the timing requirement threshold;

Question 2: Considering that the processing time of low-latency services is extremely short, the traditional timing calculation method only considers the calculation method of "the first symbol of PUCCH", which may lead to inefficient transmission, that is, the second multiplexing transmission method can be adopted In this case, the first method of discarding transmission is also used, so the timing calculation method needs to be optimized.

Fig. 3 shows a flowchart of a method for determining an uplink channel transmission mode provided by an exemplary embodiment of the present application. This method can be applied to the communication system shown in FIG. 1. The method includes:

Step 301: The base station configures multiple uplink channel resources for the UE;

Exemplarily, the resources of the uplink channel are resources used to transmit PUCCH, referred to as PUCCH resources. The base station sends downlink control information (Downlink Control Information, DCI) to the UE, and the format of the DCI may be DCI format 1_0 or DCI format 1_1. The DCI carries a downlink scheduling grant (DL grant). The DL grant is used to configure multiple PUCCH resources for the UE.

Exemplarily, the PUCCH resources include: time-frequency resources used to transmit PUCCH-ACK.

Step 302: The UE determines the uplink channel transmission mode;

Uplink channel transmission modes include: multiplex transmission mode or non-multiplex transmission mode.

Step 303: The UE sends an uplink channel to the base station;

The UE uses the determined uplink channel transmission mode to send the uplink channel to the base station.

Exemplarily, the UE uses a multiplexed transmission mode to multiplex two PUCCH-ACKs to the same PUCCH for transmission; or the UE uses a non-multiplexed transmission mode to send one PUCCH-ACK to the base station.

Step 304: The base station determines the uplink channel transmission mode;

Step 305: The base station detects and receives the uplink channel sent by the UE.

The base station detects and receives the uplink channel sent by the UE according to the determined uplink channel transmission mode.

It should be noted that this application uses at least two PUCCH-ACK multiplexing scenarios for exemplary description. However, the technical solution of the present application is also applicable to other types of PUCCH multiplexing scenarios, as well as PUCCH and PDSCH multiplexing transmission scenarios; as long as multiple uplink channels (PUCCH, PDSCH) have feedback with multiple delay requirements. For example, the multiplexing between PUCCH-ACK and PUCCH-CSI is another example where PUCCH-ACK is multiplexed to PDSCH.

The above-mentioned "determining the transmission mode of the uplink channel" can be implemented as: when the resources of at least two uplink channels overlap in the time domain, determine the time domain position between the at least one downlink channel corresponding to the at least two uplink channels and the reference resource Determine the uplink channel transmission mode according to the relationship between the time interval and the processing capability of the target UE.

Among them, the target UE processing capability is one of at least two UE processing capabilities supported by the terminal.

Fig. 4 shows a flowchart of a method for determining an uplink channel transmission mode provided by an exemplary embodiment of the present application. This method may be executed by the terminal or base station shown in FIG. 1, and the method includes:

Step 401: Determine that the resources of at least two uplink channels overlap in the time domain.

In this embodiment, the uplink channel is PUCCH, the downlink channel is PDSCH, the resources of the uplink channel are PUCCH resources, and the uplink channel transmission mode is the PUCCH transmission mode as an example.

The forms of at least two PUCCH resources overlapping in the time domain include: partially overlapping PUCCH, including, and completely overlapping. Taking at least two PUCCHs including: PUCCH resource A and PUCCH resource B as an example, (a) in Figure 5 shows a situation where PUCCH resource A and PUCCH resource B overlap in the time domain; (b) in Figure 5 A situation where PUCCH resource A and PUCCH resource B completely overlap in the time domain is shown; (c) in FIG. 5 shows a situation where PUCCH resource A and PUCCH resource B are partially overlapped in the time domain.

Exemplarily, the terminal receives the DL grant sent by the base station, where the DL grant is used to schedule the time-frequency resources of the PDSCH and schedule the feedback resources of HARQ-ACK for feeding back the PDSCH. That is, the terminal determines the PUCCH resource according to the DL grant sent by the base station.

Exemplarily, the terminal may also receive semi-static signaling (for example, n1PUCCH-AN in SRS-Config) sent by the base station to determine the PUCCH resource.

Step 402: When resources of at least two uplink channels overlap in the time domain, determine the target UE processing capability among the at least two UE processing capabilities;

Optionally, the target UE processing capability is the UE processing capability determined according to at least one downlink channel (a designated downlink channel or each downlink channel or a part of downlink channels).

In an example, the downlink channel corresponding to each uplink channel can respectively determine a target UE processing capability, and there is a one-to-one correspondence between the downlink channel and the target UE processing capability. For example, PDSCHA can determine the target UE processing capability A; PDSCHB can determine the target UE processing capability B;

In another example, the processing capability of the target UE is determined according to the designated first downlink channel, and the first downlink channel includes: the last downlink channel among the corresponding downlink channels of the at least two uplink channels; or, at least two The downlink channel with the last end position among the corresponding downlink channels among the two uplink channels; or, any one downlink channel corresponding to at least two uplink channels. In this embodiment, it is exemplified that the first downlink channel is the last PDSCH (hereinafter referred to as the first PDSCH) of the PDSCHs corresponding to all PUCCHs in at least two PUCCHs.

Exemplarily, determining the target UE processing capability in the at least two UE processing capabilities includes at least one of the following manners:

1) Determine the processing capability of the target UE according to the transmission parameters of the PDSCH.

The transmission parameters of the PDSCH include, but are not limited to: Transport Block Size (TBS) and the number of Resource Blocks (Resource Block, PRB).

When the PDSCH TBS is greater than the first threshold K, the first UE processing capability of the at least two UE processing capabilities is determined as the target UE processing capability; when the PDSCH TBS is less than the first threshold K, the at least two UE processing capabilities are determined The second UE processing capability in is determined as the target UE processing capability, so as to ensure that the large data block has a longer processing time. Wherein, when TBS is equal to the first threshold K, the processing capability of the first UE or the processing capability of the second UE is determined as the processing capability of the target UE, which is not limited.

When the PDSCH PRB is greater than the second threshold L, the first UE processing capability of the at least two UE processing capabilities is determined as the target UE processing capability; when the PDSCH PRB is less than the second threshold L, the at least two UE processing capabilities are determined The second UE processing capability in is determined as the target UE processing capability, so as to ensure that the large data block has a longer processing time. Wherein, when the PRB is equal to the second threshold L, the processing capability of the first UE or the processing capability of the second UE is determined as the processing capability of the target UE, which is not limited.

2) According to the indication of the DCI used to schedule the PDSCH, the target UE processing capability is determined among at least two UE processing capabilities.

When the PDSCH DCI is used to indicate high-latency services, the first UE processing capability of the at least two UE processing capabilities is determined as the target UE processing capability; when the PDSCH DCI is used to indicate low-latency services, at least two The second UE processing capability in the UE processing capabilities is determined as the target UE processing capability. High-latency services are services that require a delay greater than a threshold, and low-latency services are services that require a delay less than the threshold.

The processing time of the processing capability of the first UE is longer than the processing time of the processing capability of the second UE.

Step 403: Determine a timing requirement threshold according to the processing capability of the target UE;

When the processing capability of the target UE is UE processing capability 1, the processing time N _1.1 corresponding to the processing capability of the target UE is determined according to the above table _1.1 , and then the timing requirement threshold is determined as N _1,1 +d _1,1 +d _1,2 +1

When the processing capability of the target UE is UE processing capability 2, the processing time N _1.2 corresponding to the processing capability of the target UE is determined according to the above table _1.2 , and then the timing requirement threshold is determined as N _1,2 +d _1,1 +d _1,2 +1.

Step 404: Determine whether the time interval is not less than the timing requirement threshold;

In an example, the time interval includes the interval between the PDSCH corresponding to the at least two PUCCH channels and the time domain position of the reference resource, and the reference resource is one of the at least two PUCCH resources.

Calculate the time interval between the start symbol of the reference resource and the last symbol of the last PDSCH in the PDSCHs corresponding to all PUCCHs. It is determined whether the time interval is greater than the timing requirement threshold, and the timing requirement threshold is determined according to the processing time corresponding to the processing capability of the target UE.

With reference to Figure 6, suppose the reference resource is PUCCH A, the time interval between the start symbol of PUCCH A and the last symbol of PDSCH is T1, and the time between the start symbol of PUCCH A and the last symbol of the second PDSCH The interval is T2.

When all the time intervals are not less than the timing requirement threshold, go to step 405; when there is at least one time interval less than the timing requirement threshold, go to step 406.

Step 405: Determine to adopt a multiplex transmission mode;

Taking PUCCH-ACK as an example, when all time intervals are not less than the timing requirement threshold, it is determined to adopt a multiplexing transmission mode of multiplexing two PUCCH-ACKs to the same PUCCH for transmission.

Step 406: It is determined that only a part of the PUCCH is transmitted.

When there is at least one time interval less than the timing requirement threshold, it is determined to transmit only a part of the PUCCH, for example, only one PUCCH-ACK is transmitted.

In summary, the method provided in this embodiment determines the uplink channel transmission mode according to the relationship between the time interval and the processing capability of the target UE when the resources of at least two uplink channels overlap in the time domain. Since the target UE processing capability is one of the at least two UE processing capabilities supported by the terminal, it is possible to specify which UE processing capability is used to determine the uplink channel transmission mode, which solves how to perform uplink for UEs that support at least two UE processing capabilities. The problem of multiplexed transmission of control information.

Among the UE processing capabilities determined according to the PDSCH, the shorter the processing time, the stronger the processing capabilities; the longer the processing time, the weaker the processing capabilities.

In an alternative embodiment based on FIG. 4, when determining the processing capabilities of the target UE among the at least two processing capabilities, severe computing capabilities (short processing time) can also be used.

Fig. 7 shows a flowchart of a method for determining a PUCCH transmission mode provided by another exemplary embodiment of the present application. This method may be executed by the terminal or base station shown in FIG. 1, and the method includes:

The forms of at least two PUCCH resources overlapping in the time domain include: partially overlapping PUCCH, including, and completely overlapping. Taking at least two PUCCHs including: PUCCH resource A and PUCCH resource B as an example, (a) in FIG. 5 shows that PUCCH resource A and PUCCH resource B overlap in the time domain; (b) in FIG. 5 A situation where PUCCH resource A and PUCCH resource B completely overlap in the time domain is shown; (c) in FIG. 5 shows a situation where PUCCH resource A and PUCCH resource B are partially overlapped in the time domain.

Step 4021: When the resources of at least two uplink channels overlap in the time domain, the one with the shortest processing time among the UE processing capabilities determined according to the downlink channel is determined as the target UE processing capability;

Exemplarily, the processing capability of the target UE is the one with the shortest processing time among the UE processing capabilities respectively determined according to each downlink channel corresponding to all uplink channels.

Exemplarily, taking at least two UE processing capabilities including: UE processing capability 1 and UE processing capability 2 as an example, the processing capabilities N _1.1 and N _{1.2 of the} terminal for PDSCH are determined according to the PDSCH. When the processing capability of the target UE is UE processing capability 1, the processing time N _1.1 corresponding to the processing capability of the target UE is determined according to the above table 1.1. When the processing capability of the target UE is UE processing capability 2, the target is determined according to the above table 1.2 Processing time N _1.2 corresponding to the processing capability of the UE.

The processing capability corresponding to the shorter one of N _1.1 and N _1.2 is determined as the processing capability of the target UE. That is, the processing capability corresponding to min{N _1.1, N _1.2 } is determined as the processing capability of the target UE.

When the target UE processing capability is UE processing capability 1, the timing requirement threshold is determined to be N _1,1 +d _1,1 +d _1,2 +1; when the target UE processing capability is UE processing capability 2, the timing requirement threshold is determined It is N _1,2 +d _1,1 +d _1,2 +1.

Step 405: Determine to adopt a multiplex transmission mode;

Step 406: Determine to use a non-multiplexed transmission mode.

In summary, the method provided in this embodiment adopts the UE processing capability corresponding to the harsh processing capability as the target UE processing capability, which can ensure the success rate of the terminal in the PUCCH multiplexing transmission mode.

In an optional embodiment based on FIG. 4, when determining the processing capability of the target UE among the at least two processing capabilities, a loose computing capability (long processing time) may also be used.

Fig. 8 shows a flowchart of a method for determining a PUCCH transmission mode provided by another exemplary embodiment of the present application. This method may be executed by the terminal or base station shown in Figure 1, and the method includes:

Step 4022: When the resources of at least two uplink channels overlap in the time domain, the one with the longest processing time among the UE processing capabilities determined according to the downlink channel is determined as the target UE processing capability;

Exemplarily, the processing capability of the target UE is the one with the longest processing time among the UE processing capabilities respectively determined according to each downlink channel corresponding to all uplink channels.

The processing capability corresponding to the longer one of N _1.1 and N _1.2 is determined as the processing capability of the target UE. That is, the processing capability corresponding to max{N _1.1, N _1.2 } is determined as the processing capability of the target UE.

When the target UE processing capability is UE processing capability 1, the timing requirement threshold is determined to be N _1,1 +d _1,1 +d _1,2 +1; when the target UE processing capability is UE processing capability 2, according to the above table 1.2 To determine the processing time N _1.2 corresponding to the processing capability of the target UE, determine that the timing requirement threshold is N _1,2 +d _1,1 +d _1,2 +1.

Step 405: Determine to adopt a multiplex transmission mode;

Step 406: Determine to use a non-multiplexed transmission mode.

In summary, the method provided in this embodiment can ensure that the terminal has sufficient PDSCH decoding time by adopting the UE processing capability corresponding to the loose processing capability as the target UE processing capability.

The foregoing Figures 4, 7 and 8 exemplify that the reference resource is the first resource of at least two uplink channels (for example, the first PUCCH with the earliest time domain position: PUCCH A). However, in alternative embodiments based on FIG. 4, FIG. 7 and FIG. 8, the reference resource may also be one of the resources of at least two uplink channels that supports multiplexing transmission.

Fig. 9 shows a flowchart of a method for determining a PUCCH transmission mode provided by another exemplary embodiment of the present application. This method may be executed by the terminal or base station shown in FIG. 1, and the method includes:

Step 4011: Determine a reference resource, where the reference resource is a second resource used for multiplexing transmission among the resources of the at least two uplink channels.

When there are at least two PUCCH resources (PUCCH A and PUCCH B) overlapping in the time domain, determine the reference resource for multiplexing and transmitting the PUCCH A-ACK codebook and PUCCH B-ACK codebook, assuming that the reference resource is PUCCH B.

Optionally, the target UE processing capability is a UE processing capability determined according to at least one downlink channel.

Exemplarily, the at least one downlink channel includes: the last downlink channel among all the downlink channels corresponding to the at least two uplink channels; or, the downlink channel with the lowest end position among all the downlink channels corresponding to the at least two uplink channels; Or, one of all downlink channels corresponding to at least two uplink channels; or, all downlink channels corresponding to at least two uplink channels. In this embodiment, it is exemplified that the first downlink channel is the last PDSCH (hereinafter referred to as the first PDSCH) of the PDSCHs corresponding to all PUCCHs in at least two PUCCHs.

Step 405: Determine to adopt a multiplex transmission mode;

Taking PUCCH-ACK as an example, when all time intervals are not less than the timing requirement threshold, it is determined to adopt the multiplexing transmission mode of multiplexing two PUCCH-ACKs to the same PUCCH (second resource) for transmission.

Step 406: Determine to use a non-multiplexed transmission mode.

In summary, the method provided in this optional embodiment optimizes the rough and conservative calculation rules (the earliest PUCCH) to multiplex the corresponding PUCCH by optimizing the reference resources for timing calculation, which improves the use of PUCCH multiplexing transmission methods.

Candidate resources, thereby further relaxing the reuse conditions.

In the foregoing embodiment, the reference resource is determined before calculating whether the timing requirement is met. According to another aspect of the present application, after the timing requirements are determined first, the uplink channel resources that meet the timing requirements can be directly selected from the candidate uplink channel resources. That is, when the resources of at least two uplink channels overlap in the time domain, the target resource used in the multiplexing transmission mode is selected from the resources of the at least two uplink channels.

Optionally, the target resource satisfies the following first condition:

The time interval between the time domain position of the target resource and the at least one downlink channel corresponding to the at least two uplink channels is greater than the timing requirement threshold, which is determined according to the target UE capability;

The number of bits that can be carried by the target resource is not less than the number of bits to be transmitted.

The timing requirements include: the time domain position of the target resource is later than the time t2, t2=t1+{N+d _1.1 +d _1.2 +1}, where t1 is the time of the last symbol of the first downlink channel, and N is Target UE processing capability.

Optionally, the target resource also satisfies the following second condition: the target resource is the resource with the earliest start position among the resources meeting the first condition; or, the target resource is the resource with the latest start position among the resources meeting the first condition Resources.

Optionally, the at least one downlink channel includes: the last downlink channel among all downlink channels corresponding to the at least two uplink channels; or, the downlink channel with the lowest end position among all the downlink channels corresponding to the at least two uplink channels ; Or, one of all downlink channels corresponding to at least two uplink channels; or, all downlink channels corresponding to at least two uplink channels.

Optionally, the processing capability of the target UE includes: the processing capability of the UE determined according to the downlink channel; or, the one with the shortest processing time among the processing capability of the UE determined on the downlink channel corresponding to the at least two uplink channels; or, the processing time corresponding to the at least two uplink channels The one with the longest processing time among the UE processing capabilities determined by the downlink channel.

Fig. 11 shows a flowchart of a method for selecting uplink channel resources provided by another exemplary embodiment of the present application. This method can be executed by the terminal or base station shown in FIG. 1. The method includes:

Step 1101: When resources of at least two uplink channels overlap in the time domain, determine the processing capability of the target UE among the at least two UE processing capabilities;

Exemplarily, the at least one downlink channel includes: the last downlink channel among all the downlink channels corresponding to the at least two uplink channels; or, the downlink channel with the lowest end position among all the downlink channels corresponding to the at least two uplink channels; Or, one of all downlink channels corresponding to at least two uplink channels; or, all downlink channels corresponding to at least two uplink channels.

Step 1102: Calculate the timing requirement threshold according to the processing capability of the target UE;

When the processing capability of the target UE is UE processing capability 1, the processing time N _1.1 corresponding to the processing capability of the target UE is determined according to the foregoing Table _1.1 . N _1.1 is the processing capability of the terminal using UE processing capability 1 for the last PDSCH corresponding to the PUCCH. Correspondingly, the timing requirement threshold corresponding to UE processing capability 1 is N _1,1 +d _1,1 +d _1,2 +1.

When the processing capability of the target UE is UE processing capability 2, the processing time N _1.2 corresponding to the processing capability of the target UE is determined according to the foregoing Table _1.2 . N _1.2 is the processing capability of the terminal using UE processing capability 2 to process the last PDSCH corresponding to the PUCCH. Correspondingly, the timing requirement threshold corresponding to UE processing capability 2 is N _1,2 +d _1,1 +d _1,2 +1.

Step 1103: Determine the target resource that meets the timing requirement threshold on the resources of the at least two uplink channels.

This step includes the following sub-steps:

1. Determine the time t1 of the last symbol of the last PDSCH (first downlink channel) corresponding to at least two PUCCHs;

2. Determine the time t2 corresponding to t1+{N+d _1.1 +d _1.2 +1} as the earliest time to meet the timing requirements;

3. Determine the PUCCH resource that meets the first condition as the target resource.

The first condition includes: the time domain position of the target resource is later than time t2; the number of bearable bits of the target resource is not less than the number of bits to be transmitted.

When more than one resource meets the first condition, the second condition can also be satisfied at the same time:

The target resource is the resource with the earliest start position among the resources meeting the first condition; or, the target resource is the resource with the latest start position among the resources meeting the first condition.

As an illustrative example, as shown in FIG. 12, the terminal is pre-configured with a group PUCCH resource set (see the upper part of FIG. 11). Step 1. The terminal separately determines PUCCHs, PUCCH A and PUCCH B corresponding to two PDSCHs according to a downlink scheduling grant (DL grant); wherein, PUCCH A and PUCCH B overlap in time domain position. Step 2: The terminal determines the time domain position t2 according to the last symbol of the last PDSCH and timing requirements (N ₁ +d _1,1 +d _1,2 +1). Step 3: The terminal finds after t2 from the pre-configured PUCCH resource set; the capacity can carry 2-bit HARQ-ACK; and the earliest PUCCH resource, such as the PUCCH resource filled with diagonal lines in FIG. 1, that is, the third PUCCH resource. Step 4. The terminal sends a 2-bit HARQ-ACK on the third PUCCH resource.

In summary, the method provided in this embodiment directly selects a suitable target resource from the resource set of the uplink channel according to the timing requirement threshold, instead of using reference resources to determine whether the timing relationship is satisfied, thereby providing the probability of multiplexing.

It should be noted that the embodiment shown in FIG. 11 may also be applicable to a terminal that supports only one type of UE processing capability. In this case, the target UE processing capability is the UE processing capability supported by the terminal.
