The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functionality may differ, for example in LTE systems, called eNodeB or eNB; in a 5G NR-U system, it is called gNodeB or gNB.

The access network device 120 and the terminal 13 communicate with each other through some air interface technology, for example, a Uu interface.
In NR, the flexibility of PUCCH structure design results in their starting and ending symbols not necessarily being 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 a fixed timing requirement to be multiplexed, otherwise, the terminal will reserve one PUCCH.
The multiplexing timing requirements between PUCCH and PDSCH are as follows, as shown in fig. 2:

Wherein, N1 is the capability of processing PDSCH reported by the terminal.
2. First OFDM symbol of earliest transmitted channel of PUCCH with time domain overlapped to last of DCI scheduling HARQ-ACKThe time difference T2 of OFDM symbol is greater than N2+d 2,1+1 symbols. Wherein, N2 is the time for processing PDSCH reported by the terminal.

For UE processing capability 2: if the PDSCH is of mapping type B, if the number of allocated PDSCH symbols is 2 or 4, d1.2Is the number of overlapping symbols of the scheduled PDCCH and the scheduled PDSCH.
Terminal processing capability
After receiving the downlink scheduling information carried in the DCI format 1_0 or 1_1, the terminal receives the corresponding PDSCH in the corresponding time slot, and sends feedback HARQ-ACK information to the base station. The time for starting to send HARQ-ACK by the UE is later than T after the end of the last symbol for bearing PDSCHproc,1=[(N 1+d 1,1+d 1,2)(2048+144)·k2 -u]·T CTime of (d).
If this requirement is not met, the terminal will not send a HARQ-ACK. Where N1 has different values depending on the processing capabilities of the UE.

PUCCH-ACK resource determination procedure
The terminal obtains N PUCCH-ACK resources { PUCCH resource 0, PUCCH resource 1, PUCCH resource 2, PUCCH resource N-1}, wherein N > -1 through semi-static signaling. The PUCCH resources are grouped by capacity (the number of bits carrying UCI) into at least two groups, such as { PUCCH resource set 0, PUCCH resource set 1, PUCCH resource set 2, PUCCH resource set 3 }. The number of UCI bits which can be carried by PUCCH resources in the PUCCH resource set 0 is less than or equal to 2; the number of UCI bits which can be carried by PUCCH resources in the PUCCH resource set 1 is more than 2 and less than or equal to X1; the number of UCI bits which can be carried by PUCCH resources in the PUCCH resource set 2 is greater than X1 and less than or equal to X2; the number of UCI bits which can be carried by PUCCH resources in the PUCCH resource set 3 is greater than X2 and less than or equal to X3; x1, X2, X3 are configured by a network.
And the terminal selects one PUCCH resource from the PUCCH resource set according to a PUCCH resource index (PUCCH resource indicator) in a downlink scheduling grant (DL grant) and the UCI bit number and transmits UCI.
Firstly, the terminal selects a PUCCH resource set i according to the UCI bit number Y, wherein Y is within the capacity range of the PUCCH resource set i. And secondly, the terminal selects one 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), a terminal has different UE processing capabilities for different types of data, i.e., the terminal has at least two UE processing capabilities simultaneously for a period of time.
Problem 1: calculating a timing requirement threshold based at least on which UE processing capability;
problem 2: considering that the requirement of 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" may cause inefficient transmission, that is, the case of the 2 nd multiplexing transmission method can be adopted, and the first discarding transmission method is also adopted, so that the timing calculation method needs to be optimized.
Fig. 3 is a flowchart illustrating a method for determining an uplink channel transmission mode according to an exemplary embodiment of the present application. The method may be applied in the communication system shown in fig. 1. The method comprises the following steps:
step 301, a base station configures resources of a plurality of uplink channels to a UE;
for example, the resource of the uplink channel is a resource for transmitting a PUCCH, which is abbreviated as a PUCCH resource. The base station sends Downlink Control Information (DCI) to the UE, where the DCI format may be DCI format 1_0 or DCI format 1_ 1. The DCI carries a downlink scheduling grant (DLgrant). The DLgrant is used to configure a plurality of PUCCH resources to the UE.
Illustratively, the PUCCH resources include: time-frequency resources for transmission of PUCCH-ACK.
Step 302, the UE determines an uplink channel transmission mode;
the uplink channel transmission mode comprises the following steps: a multiplexing transmission mode or a non-multiplexing transmission mode.
Step 303, the UE sends an uplink channel to the base station;
and the UE sends the uplink channel to the base station by adopting the determined uplink channel transmission mode.
Illustratively, the UE multiplexes two PUCCH-ACKs to the same PUCCH for transmission by using a multiplexing transmission method; or the UE sends one PUCCH-ACK to the base station by adopting a non-multiplexing transmission mode.
Step 304, the base station determines the transmission mode of the uplink channel;
step 305, the base station detects and receives an uplink channel sent by the UE.
And 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 the present application is exemplified by a multiplexing scenario of at least two PUCCH-ACKs. But the technical scheme of the application is also suitable for other types of PUCCH multiplexing scenes and PUCCH and PDSCH multiplexing transmission scenes; as long as there is feedback with multiple delay requirements in multiple uplink channels (PUCCH, PDSCH). For example, the multiplexing between PUCCH-ACK and PUCCH-CSI, and for example, the case of PUCCH-ACK multiplexing to PDSCH.
The "determining the transmission mode of the uplink channel" may be implemented as follows: when resources of at least two uplink channels are overlapped on a time domain, determining a time interval between at least one downlink channel corresponding to the at least two uplink channels and a time domain position of a reference resource; and determining an uplink channel transmission mode according to the relation between the time interval and the processing capacity of the target UE.
Wherein the target UE processing capability is one of at least two UE processing capabilities supported by the terminal.
Fig. 4 is a flowchart illustrating a method for determining an uplink channel transmission mode according to an exemplary embodiment of the present application. The method may be performed by a terminal or a base station shown in fig. 1, and the method includes:
step 401, determining that resources of at least two uplink channels are overlapped on a time domain;
in this embodiment, the uplink channel is a PUCCH, the downlink channel is a PDSCH, the resource of the uplink channel is a PUCCH resource, and the uplink channel transmission mode is a PUCCH transmission mode as an example.
The form in which at least two PUCCH resources overlap in the time domain includes: partially overlapping PUCCH, inclusive, fully overlapping. The at least two PUCCHs include: PUCCH resource a and PUCCH resource B are taken as examples, and fig. 5 (a) shows a case where PUCCH resource a and PUCCH resource B include overlapping in the time domain; fig. 5 (B) shows a case where PUCCH resource a and PUCCH resource B completely overlap in the time domain; fig. 5 (c) shows a case where PUCCH resource a and PUCCH resource B are partially overlapped in the time domain.
Illustratively, the terminal receives a DLgrant sent by the base station, where the DLgrant is used for scheduling time-frequency resources of the PDSCH and scheduling feedback resources for feeding back HARQ-ACK of the PDSCH. That is, the terminal determines the PUCCH resource according to the DLgrant transmitted by the base station.
Illustratively, the terminal may also receive semi-static signaling (e.g., n1PUCCH-AN in SRS-Config) sent by the base station, and determine the PUCCH resource.
Step 402, when there is overlap of resources of at least two uplink channels in time domain, determining a target UE processing capability of at least two UE processing capabilities;
optionally, the target UE processing capability is a UE processing capability determined according to at least one downlink channel (one designated downlink channel or each downlink channel or a part of downlink channels).
In one example, the downlink channel corresponding to each uplink channel can determine a target UE processing capability, and the downlink channel and the target UE processing capability have a one-to-one correspondence relationship. For example, pdschha can determine the target UE processing capability a; the PDSCHB can determine the processing capability B of the target UE;
in another example, the target UE processing capability is determined based on a specified first downlink channel comprising: a last downlink channel in corresponding downlink channels in the at least two uplink channels; or, the downlink channel with the most backward end position in the corresponding downlink channels in the at least two uplink channels; or any one downlink channel corresponding to the at least two uplink channels. In this embodiment, the first downlink channel is a last PDSCH (hereinafter referred to as a first PDSCH) of PDSCHs corresponding to all PUCCHs of the at least two PUCCHs.
Illustratively, determining the target UE processing capability of the at least two UE processing capabilities comprises at least one of:
1) the target UE processing capability is determined according to the transmission parameters of the PDSCH.
Transmission parameters of PDSCH include, but are not limited to: transport Block Size (TBS), number of resource blocks (PRB).
When the TBS of the PDSCH is larger than a first threshold K, determining a first UE processing capability of at least two UE processing capabilities as a target UE processing capability; and when the TBS of the PDSCH is smaller than the first threshold K, determining a second UE processing capability of the at least two UE processing capabilities as a target UE processing capability so as to ensure that the large data block has a longer processing time. When TBS is equal to the first threshold K, the first UE processing capability or the second UE processing capability is determined as the target UE processing capability, which is not limited herein.
When the PRB of the PDSCH is larger than a second threshold value L, determining a first UE processing capability of at least two UE processing capabilities as a target UE processing capability; and when the PRB of the PDSCH is smaller than a second threshold value L, determining a second UE processing capability of the at least two UE processing capabilities as a target UE processing capability so as to ensure that the large data block has the purpose of longer processing time. When the PRB is equal to the second threshold L, the first UE processing capability or the second UE processing capability is determined as the target UE processing capability, which is not limited herein.
2) And according to the DCI instruction for scheduling the PDSCH, determining the processing capability of the target UE from the processing capabilities of the at least two UEs.
When the DCI of the PDSCH is used for indicating the high-delay service, determining a first UE processing capability of at least two UE processing capabilities as a target UE processing capability; and when the DCI of the PDSCH is used for indicating the low-latency service, determining a second UE processing capability of the at least two UE processing capabilities as a target UE processing capability. The high delay service is a service requiring a delay greater than a threshold, and the low delay service is a service requiring a delay less than a threshold.
Wherein the processing time of the first UE processing capability is longer than the processing time of the second UE processing capability.
Step 403, determining a timing requirement threshold according to the processing capability of the target UE;
when the processing capacity of the target UE is the processing capacity 1 of the UE, the processing time N corresponding to the processing capacity of the target UE is determined according to the table 1.11.1And further determining the timing requirement threshold to be N1,1+d 1,1+d 1,2+1
When the processing capacity of the target UE is the processing capacity 2 of the UE, the processing time N corresponding to the processing capacity of the target UE is determined according to the table 1.21.2And further determining the timing requirement threshold to be N1,2+d 1,1+d 1,2+1。
Step 404, judging whether the time interval is not less than a time sequence requirement threshold value;
in one example, the time interval includes an interval between PDSCH corresponding to the at least two PUCCH channels, respectively, and a time domain location of a reference resource, the reference resource being one of the at least two PUCCH resources.
And calculating the time interval between the starting symbol of the reference resource and the last symbol of the last PDSCH in the PDSCHs corresponding to all PUCCHs. And judging whether the time interval is larger than a timing requirement threshold value, wherein the timing requirement threshold value is determined according to the processing time corresponding to the processing capability of the target UE.
Referring to fig. 6 in combination, let reference resource be PUCCH a, time interval between the starting symbol of PUCCH a and the last symbol of PDSCH be T1, and time interval between the starting symbol of PUCCH a and the last symbol of second PDSCH be T2.
When all the time intervals are not smaller than the timing requirement threshold, entering step 405; when there is at least one time interval less than the timing requirement threshold, step 406 is entered.
Step 405, determining to adopt a multiplexing transmission mode;
taking the PUCCH-ACK as an example, when all time intervals are not smaller than the time sequence requirement threshold, a multiplexing transmission mode of multiplexing two PUCCHs-ACKs to the same PUCCH for transmission is determined.
At step 406, it is determined that only a portion 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 portion of the PUCCH, such as only one PUCCH-ACK.
In summary, in the method provided in this embodiment, when there is at least two uplink channel resources overlapping in the time domain, the uplink channel transmission mode is determined according to the relationship between the time interval and the target UE processing capability. Because the target UE processing capability is one of at least two UE processing capabilities supported by the terminal, which UE processing capability is adopted to determine the uplink channel transmission mode can be determined clearly, and the problem of how to perform multiplexing transmission of the uplink control information for the UE supporting at least two UE processing capabilities is solved.
Among the UE processing capabilities determined according to the PDSCH, the shorter the processing time is, the stronger the processing capability is; the longer the processing time, the weaker the processing power.
In an alternative embodiment based on fig. 4, also severe computational power (short processing time) may be employed when determining the target UE processing capability of the at least two processing capabilities.
Fig. 7 is a flowchart illustrating a method for determining a PUCCH transmission scheme according to another exemplary embodiment of the present application. The method may be performed by a terminal or a base station shown in fig. 1, and the method includes:
step 401, determining that resources of at least two uplink channels are overlapped on a time domain;
in this embodiment, the uplink channel is a PUCCH, the downlink channel is a PDSCH, the resource of the uplink channel is a PUCCH resource, and the uplink channel transmission mode is a PUCCH transmission mode as an example.
The form in which at least two PUCCH resources overlap in the time domain includes: partially overlapping PUCCH, inclusive, fully overlapping. The at least two PUCCHs include: PUCCH resource a and PUCCH resource B are taken as examples, and fig. 5 (a) shows a case where PUCCH resource a and PUCCH resource B include overlapping in the time domain; fig. 5 (B) shows a case where PUCCH resource a and PUCCH resource B completely overlap in the time domain; fig. 5 (c) shows a case where PUCCH resource a and PUCCH resource B are partially overlapped in the time domain.
Illustratively, the terminal receives a DLgrant sent by the base station, where the DLgrant is used for scheduling time-frequency resources of the PDSCH and scheduling feedback resources for feeding back HARQ-ACK of the PDSCH. That is, the terminal determines the PUCCH resource according to the DLgrant transmitted by the base station.
Illustratively, the terminal may also receive semi-static signaling (e.g., n1PUCCH-AN in SRS-Config) sent by the base station, and determine the PUCCH resource.
Step 4021, when there is an overlap of resources of at least two uplink channels in the time domain, determining the shortest processing time of the processing capacities of the UEs determined according to the downlink channels as the processing capacity of the target UE;
for example, the target UE processing capability is the one with the shortest processing time among the UE processing capabilities respectively determined according to the downlink channels corresponding to all uplink channels
Illustratively, at least two UE processing capabilities include: UE processing capacity 1 and UE processing capacity 2 are taken as examples, and the processing capacity N of the terminal for the PDSCH is determined according to the PDSCH1.1And N1.2. When the processing capacity of the target UE is the processing capacity 1 of the UE, the processing time N corresponding to the processing capacity of the target UE is determined according to the table 1.11.1When the processing capacity of the target UE is the processing capacity 2 of the UE, the processing time corresponding to the processing capacity of the target UE is determined according to the table 1.2N 1.2
Will N1.1And N1.2The shorter one of the processing capacities is determined as the target UE processing capacity. That is, will min { N }1.1,N 1.2And determining the corresponding processing capacity as the processing capacity of the target UE.
Step 403, determining a timing requirement threshold according to the processing capability of the target UE;
