Embodiment

[0173] Assume that a time slot is divided into 4 sub-slots, wherein the length of the first and fourth sub-slots is 4 symbols, and the length of the second and third sub-slots is 3 symbols. Assume that according to the K1 indication in the PDCCH scheduling PDSCH (in sub-slot units, it is used to indicate the sub-slot interval between the end position of PDSCH and the sub-slot for transmitting its HARQ-ACK), it is determined that there are 4 PDSCHs that need to be in HARQ-ACK feedback is performed in the second sub-slot in time slot n+2, and it is determined that there are 2 PDSCHs that need to perform HARQ-ACK feedback in the fourth sub-slot in time slot n+2. Assume that each PDSCH corresponds to 1-bit HARQ-ACK; assume that high-level signaling pre-configures two PUCCH resource sets for the terminal, and the first PUCCH resource set contains 8 resources, corresponding to the transmission of 1 to 2-bit UCI. Each PUCCH resource The specific information includes the corresponding...

Abstract

Embodiments of the present invention provide a PUCCH resource determination method and communication equipment, the method comprising: determining the PUCCH resource, and determining the sub-slot where the PUCCH transmission is located; according to the PUCCH resource, determining the PUCCH transmission in the sub-slot Resources. In this way, the PUCCH resources can be determined in sub-slot units without increasing the PUCCH resource configuration overhead. The embodiments of the present invention can improve the transmission efficiency of the PUCCH.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for determining a physical uplink control channel (Physical Uplink Control Channel, PUCCH) resource and a communication device. Background technique [0002] In the communication process, the terminal often needs to send a PUCCH carrying uplink control information (Uplink Control Information, UCI) to the network side device, for example: carrying hybrid automatic repeat request acknowledgment (Hybrid Automatic Repeat request Acknowledgment, HARQ-ACK), channel state information (Channel The PUCCH of at least one of State Information (CSI) and Scheduling Request (Scheduling Request, SR). However, the current communication system only supports the transmission of one PUCCH bearing UCI in one slot (slot), that is, the PUCCH resources are determined in units of slots, which leads to relatively low transmission efficiency of the PUCCH. Contents of the in...
