Abstract

Embodiments of the present invention provide a hybrid automatic repeat request acknowledgment feedback method and a terminal, the method including: determining the feedback mode of the multiple HARQ-ACK feedbacks in the same time slot according to the control information corresponding to multiple HARQ-ACKs ; Feedback the multiple HARQ-ACKs in the time slot according to the feedback manner. The embodiments of the present invention can improve the flexibility of feeding back HARQ-ACK.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a hybrid automatic repeat request acknowledgment (Hybrid Automatic Repeat request Acknowledgment, HARQ-ACK) feedback method and terminal. Background technique [0002] At present, terminals in the communication system can support multiple transmission and reception point (Transmission Reception Point, TRP) scenarios. In this scenario, multiple TRPs can transmit multiple physical downlink control channels (PDCCH) and multiple physical downlink control channels (PDCCH) to the same terminal. Downlink shared channel (Physical downlink shared channel, PDSCH). In addition, in a multi-TRP scenario, the terminal feedback Hybrid Automatic Repeat request Acknowledgment (HARQ-ACK) often adopts a fixed configuration feedback mode, which leads to poor flexibility for the terminal to feed back the HARQ-ACK. Contents of the invention [0003] Embodiments of the present inventi...
