Title:
METHOD AND DEVICE FOR ALLOCATING SIDELINK RESOURCE IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/206483
Kind Code:
A1
Abstract:
Proposed is a method for performing wireless communication by a first device. The method may comprise the steps of: receiving, from a base station, information related to a configured grant (CG) for scheduling a sidelink resource; and on the basis of the information related to the CG, performing sidelink transmission to a second device on the basis of a sidelink resource allocated by the CG. For example, the information related to the CG may include information relating to an offset related to the CG and information relating to a period related to the CG. For example, the sidelink resource allocated by the CG may be positioned in a slot spaced apart by the offset related to the CG from the closest logical sidelink slot after a time point at which a system frame number (SFN) corresponds to 0. For example, the sidelink resource allocated by the CG may repeat at the period related the CG. For example, the period related to the CG and the offset related to the CG may be in units of logical sidelink slots. For example, the logical sidelink slot may be a resource within a sidelink resource pool.
