Title:
METHOD AND DEVICE FOR SELECTING SIDELINK TRANSMISSION RESOURCE IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/091354
Kind Code:
A1
Abstract:
Proposed is a method for performing wireless communication by a first device. The method may comprise a step of: transmitting a physical sidelink shared channel (PSSCH) through a resource selected in a first time area to a second device; receiving a physical sidelink feedback channel (PSFCH) related to the PSSCH from the second device; and on the basis that the interval between the first time area and a second time area is larger than a preconfigured threshold value, selecting a resource in the second time area to retransmit the PSSCH to the second device. For example, the first time area may precede the PSFCH. For example, the second time area may follow the PSFCH.
