Abstract
A HARQ-ACK feedback method and apparatus are provided, so as to solve a problem that a terminal cannot perform HARQ-ACK feedback in a case that the terminal is configured with a DL SPS. The method may be applied to a terminal. The method includes determining, based on first information, a HARQ-ACK codebook corresponding to M DL SPS configurations; where the first information includes at least one of the following: first HARQ-ACK feedback indication information, first TDD configuration information, or first dynamic slot format information; and M≥1, and M is an integer.

A hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback method, applied to a terminal, wherein the method comprises:
- determining, based on first information, a HARQ-ACK codebook corresponding to M downlink semi-persistent scheduling (DL SPS) configurations;
- wherein
- the first information comprises at least one of the following:
- first HARQ-ACK feedback indication information, first time division duplexing (TDD) configuration information, or first dynamic slot format information;
- and M≥1, and M is an integer;
- in a case that the HARQ-ACK codebook is determined based on a first time domain resource indicated by the first HARQ-ACK feedback indication information, and the first time domain resource collides with a downlink time domain resource indicated by the first TDD configuration information, the method further comprises:
- determining, based on the first TDD configuration information, a second time domain resource for transmitting the HARQ-ACK codebook.
A terminal, comprising a processor, a memory, and a program or instructions stored in the memory and capable of running on the processor, wherein when the program or instructions are executed by the processor, an HARQ-ACK feedback method is implemented, wherein the method comprises:
- determining, based on first information, a HARQ-ACK codebook corresponding to M downlink semi-persistent scheduling (DL SPS) configurations;
- wherein
- the first information comprises at least one of the following:
- first HARQ-ACK feedback indication information, first time division duplexing (TDD) configuration information, or first dynamic slot format information;
- and M≥1, and M is an integer;
- in a case that the HARQ-ACK codebook is determined based on a first time domain resource indicated by the first HARQ-ACK feedback indication information, and the first time domain resource collides with a downlink time domain resource indicated by the first TDD configuration information, the method further comprises:
- determining, based on the first TDD configuration information, a second time domain resource for transmitting the HARQ-ACK codebook.
A chip, wherein the chip comprises a processor and a communication interface, the communication interface is coupled to the processor, and the processor is configured to run a program or instructions to implement an HARQ-ACK feedback method, wherein the method comprises:
- determining, based on first information, a HARQ-ACK codebook corresponding to M downlink semi-persistent scheduling (DL SPS) configurations;
- wherein
- the first information comprises at least one of the following:
- first HARQ-ACK feedback indication information, first time division duplexing (TDD) configuration information, or first dynamic slot format information;
- and M≥1, and M is an integer;
- in a case that the HARQ-ACK codebook is determined based on a first time domain resource indicated by the first HARQ-ACK feedback indication information, and the first time domain resource collides with a downlink time domain resource indicated by the first TDD configuration information, the method further comprises:
- determining, based on the first TDD configuration information, a second time domain resource for transmitting the HARQ-ACK codebook.
