Method and apparatus for processing signal of sidelink feedback channel in wireless communication system

A method performed by a second user equipment (UE) for vehicle-to-everything (V2X) in a wireless communication system, the method comprising:

• receiving, from a base station (BS), configuration information for a sidelink, the configuration information comprising a resource pool;
• receiving, from a first UE, sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH) based on the configuration information;
• receiving, from the first UE, a sidelink data on the PSSCH based on the SCI;
• and
• transmitting, to the first UE, hybrid automatic repeat request-acknowledgement (HARQ-ACK) information for the sidelink data on a physical sidelink feedback channel (PSFCH),
• wherein the configuration information includes at least one of a period of a resource of the PSFCH or a time gap between the PSFCH and the PSSCH.

A first user equipment (UE) for vehicle-to-everything (V2X) in a wireless communication system, the first UE comprising:

• a transceiver configured to transmit or receive a signal;
• and
• at least one processor coupled with the transceiver and configured to:
• receive, from a base station (BS), configuration information for a sidelink, the configuration information comprising a resource pool,
• transmit, to a second UE, sidelink control information (SCI) for scheduling a physical sidelink shared channel (PSSCH) based on the configuration information,
• transmit, to the second UE, a sidelink data on the PSSCH based on the SCI, and
• receive, from the second UE, hybrid automatic repeat request-acknowledgement (HARQ-ACK) information for the sidelink data on a physical sidelink feedback channel (PSFCH),
• wherein the configuration information includes at least one of a period of a resource of the PSFCH or a time gap between the PSFCH and the PSSCH.
