Abstract
A communication method, performed by a first terminal, includes sending a physical sidelink shared channel (PSSCH) to a second terminal; determining N physical sidelink feedback channel (PSFCH) occasions for the PSSCH in M PSFCH occasions, wherein N is greater than or equal to 1 and less than or equal to M, a value of M is a number of PSFCH occasions mapped to the PSSCH, and N and M are positive integers; and receiving and decoding hybrid automatic repeat request (HARQ) information corresponding to the PSSCH sent by a second terminal, on the N PSFCH occasions.
Claims17
A communication method, performed by a first terminal, the method comprising:
- sending a physical sidelink shared channel (PSSCH) to a second terminal;
- determining N physical sidelink feedback channel (PSFCH) occasions for the PSSCH in M PSFCH occasions, wherein N is greater than or equal to 1 and less than or equal to M, a value of M is a number of PSFCH occasions mapped to the PSSCH, and N and M are positive integers;
- and
- receiving and decoding hybrid automatic repeat request (HARQ) information corresponding to the PSSCH sent by a second terminal, on the N PSFCH occasions.
A communication method, performed by a second terminal, comprising:
- receiving a physical sidelink shared channel (PSSCH) sent by a first terminal;
- determining N physical sidelink feedback channel (PSFCH) occasions for the PSSCH in M PSFCH occasions, wherein N is greater than or equal to 1 and less than or equal to M, a value of M is a number of PSFCH occasions mapped to the PSSCH, and N and M are positive integers;
- and
- performing listen-before-talk (LBT) on one or more PSFCH occasions among the N PSFCH occasions, and sending hybrid automatic repeat request (HARQ) information corresponding to the PSSCH to the first terminal on a PSFCH occasion where the LBT is successfully performed.
13-14. (canceled)
A communication device, comprising:
- a processor and a memory configured to store instructions executable by the processor;
- wherein the processor is configured to:
- send a physical sidelink shared channel (PSSCH) to a second terminal;
- determine N physical sidelink feedback channel (PSFCH) occasions for the PSSCH in M PSFCH occasions, wherein N is greater than or equal to 1 and less than or equal to M, a value of M is a number of PSFCH occasions mapped to the PSSCH, and N and M are positive integers;
- and
- receive and decode hybrid automatic repeat request (HARQ) information corresponding to the PSSCH sent by a second terminal, on the N PSFCH occasions.
