Abstract

An embodiment of the present invention provides a HARQ-ACK feedback method and a terminal. The method includes: acquiring a feedback timing set, where the basic unit of the feedback timing in the feedback timing set is less than one time slot; generating a HARQ ACK according to the feedback timing set. ‑ACK feedback information and feedback in the uplink time slot. The embodiment of the present invention provides a specific method for generating a semi-static codebook when the granularity of the feedback timing changes, so as to ensure that the HARQ-ACK for downlink transmission can be fed back normally.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a HARQ-ACK feedback method and a terminal. Background technique [0002] Currently, in an NR (New Radio, New Radio) communication system, HARQ-ACK (Hybrid Automatic Repeat request-ACK, Hybrid Automatic Repeat Request-ACK) feedback is supported using a semi-static codebook and a dynamic codebook scheme. When the terminal is configured to use the semi-static HARQ-ACK codebook, the UE (terminal) first feeds back the timing (K1), semi-static time slot structure (if configured) and PDSCH (Physical Downlink Shared Channel) according to the HARQ-ACK feedback timing (Physical Downlink Shared Channel). Shared channel) candidate time domain resource allocation information to determine the PDSCH location set M on each carrier c corresponding to the HARQ-ACK feedback in the same time slot n A，c . Then according to M A，c , the HARQ-ACK of the PDSCH received in the PDS...
