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

Abstract

The invention discloses a method for determining physical uplink control channel (PUCCH) resources, a terminal device and a network device, which are used for implicitly indicating more PUCCH resources through fields which are limited in bit number and are used for indicating the PUCCH resources. The method comprises: the terminal device determining PUCCH resources corresponding to downlink control signaling DCI according to at least one kind of information, wherein the at least one kind of information comprises one or more of the following combinations, a CORESET index where the DCI is located, a searching spatial index, a symbol index where downlink control information is carried in DCI; a monitoring symbol moitoringSymbolsWithinSlot parameter in a time slot in the searching space wherethe DCI is located, and an initial control channel element (CCE) index of a physical downlink control channel (PDCCH) where the DCI is located; and sending the PUCCH on the PUCCH resource. According to the embodiments of the present invention, more PUCCH resources can be implicitly indicated without increasing the bits of the ARI field in the DCI, thereby 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...
