Abstract

The present invention provides a PUCCH sending method, a PUCCH receiving method, a terminal and a base station. The PUCCH sending method comprises the steps: receiving at least two downlink transmissions, HARQ-ACKs of the at least two downlink transmissions being transmitted in the same time unit; determining PUCCH resources for transmitting HARQ-ACKs of the at least two downlink transmissions according to the PUCCH resources indicated by the PRI in the downlink control information DCI used by the PDCCHs corresponding to the at least two downlink transmissions respectively; and sending the corresponding HARQ-ACK of the downlink transmission on the determined PUCCH resource, so that the rapid HARQ-ACK feedback can be realized, and the HARQ-ACK feedback time delay is reduced.

Description

technical field

[0001] The present invention relates to the field of communication technologies, and in particular to a PUCCH (Physical Uplink ControlCHannel, Physical Uplink Control Channel) sending method, receiving method, terminal and base station. Background technique

[0002] In the wireless communication system, considering the complexity of implementation and standardization, currently only supports the transmission of a PUCCH carrying HARQ-ACK (Hybrid Automatic Repeat reQuest Acknowledgment, Hybrid Automatic Repeat Request Acknowledgment) in one time slot. Timing determines that multiple HARQ-ACKs that need to be transmitted in the same time slot are all transmitted on the same PUCCH. For example, HARQ-ACK of one or more PDSCHs (Physical Downlink Shared CHannel, physical downlink shared channel) that needs to be fed back by HARQ-ACK in the same time slot and / or indicate downlink SPS (Semi-persistent Scheduling, semi-persistent scheduling) The HARQ-ACK of the PDCCH ...
