METHOD AND DEVICE FOR DETERMINING FEEDBACK RESOURCE IN NR V2X

WIPO Patent Application WO/2021/006500

A1

A method for performing wireless communication by a first device and a device for supporting same are provided. The method may comprise the steps of: receiving a physical sidelink shared channel (PSSCH) from a second device; determining a physical sidelink feedback channel (PSFCH) resource associated with the PSSCH; and transmitting hybrid automatic repeat request (HARQ) feedback to the second device on the PSFCH resource. Here, the PSFCH resource can be determined on the basis of a sub channel associated with the PSSCH, a slot associated with the PSSCH, a cast type of communication between the first device and the second device, an ID of the first device, and a source ID of the second device.
