Abstract

Provided in the present invention are a method performed by user equipment and user equipment. The method comprises: determining sidelink resource pool configuration information; receiving a PSCCH and a corresponding PSSCH transmitted by another user equipment; and determining an initialization sequence parameter c init of a cyclic shift α 1 of a sequence for a physical sidelink feedback channel (PSFCH).

Claims (12)

1. A method performed by user equipment, comprising:

transmitting a physical sidelink feedback channel (PSFCH), wherein the PSFCH is used for carrying sidelink HARQ-ACK, and

generating a cyclic shift α 1 of a sequence for the PSFCH based on a value of an initialization sequence parameter c init , wherein

the cyclic shift α 1 is generated based on a sequence initialized with the value of the initialization sequence parameter c init ,

the value of the initialization sequence parameter c init is equal to a value of a PSFCH hopping identification if configured; and

if the value of the PSFCH hopping identification is not configured, the value of the initialization sequence parameter c init is 0.

2. User equipment, comprising:

transmission circuitry configured to transmit a physical sidelink feedback channel (PSFCH), wherein the PSFCH is used for carrying sidelink HARQ-ACK, and

processing circuitry configured to generate a cyclic shift α 1 of a sequence for the PSFCH based on a value of an initialization sequence parameter c init , wherein

the cyclic shift α 1 is generated based on a sequence initialized with the value of the initialization sequence parameter c init ,

the value of the initialization sequence parameter c init is equal to a value of a PSFCH hopping identification if configured; and

if the value of the PSFCH hopping identification is not configured, the value of the initialization sequence parameter c init is 0.
