Method for determining pucch resources, terminal equipment and network equipment

Abstract

The present application discloses a method for determining PUCCH resources of a physical uplink control channel, a terminal device and a network device, which are used to implicitly indicate more PUCCH resources through a field with a limited number of bits used to indicate PUCCH resources. The method includes: the terminal device determines the PUCCH resource corresponding to the downlink control signaling DCI according to at least one type of information, the at least one type of information includes one or more of the following combinations; the CORESET index where the DCI is located; the search space index ; the symbol index where the downlink control information is carried in the DCI; the monitoring symbol monitoringSymbolsWithinSlot parameter in the time slot in the search space where the DCI is located; the sequence number that appears in the time slot where the search space where the DCI is located; The PUCCH is sent on the PUCCH resource. The embodiment of the present invention can implicitly indicate more PUCCH resources without increasing the bits of the ARI field in the DCI, increasing the flexibility in the use process.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a method for determining resources of a physical uplink control channel (Physical Uplink Control Channel, PUCCH), a terminal device and a network device. Background technique [0002] New radio (New Radio, NR or New Air Interface) introduces various PUCCH structures, for example, a short PUCCH structure supporting 1 to 2 symbol lengths, a long PUCCH structure supporting 4-14 symbol lengths, and the like. [0003] The uplink control signaling UCI in the NR system needs to be carried by the PUCCH, and the PUCCH resource is generally determined through radio resource control (Radio Resource Control, RRC) pre-configuration combined with the dynamic indication of the downlink control signaling DCI. During actual application, when the number of configured PUCCH resources is greater than the number of PUCCH resources that can be indicated by the field used to indicate PUCCH r...

AI Technical Summary

Problems solved by technology

In the actual application process, when the number of configured PUCCH resources is greater than the number of PUCCH resources that can be indicated by the field used to indicate PUCCH resources in DCI, all PUCCH resources will not be indicated

For example, the number of configured PUCCH resources is 8, and the corresponding acknowledgment resource indication (ACK / NACK Resource Indication, ARI) field in the DCI has only 2 bits, and the ARI field can only indicate 4 PUCCH resources at most, and cannot indicate Display all 8 PUCCH resources
