Title:
METHOD AND DEVICE FOR PERFORMING SL COMMUNICATION ON BASIS OF RESOURCE ALLOCATION MODE 1 IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/086051
Kind Code:
A1
Abstract:
Provided are a method for performing wireless communication by a first device and a device for supporting same. The method comprises the steps of: receiving information related to a configured grant (CG) resource from a base station, the CG resource including at least one of a first resource related to CG type 1 and a second resource related to CG type 2; receiving information related to a dynamic grant (DG) resource from the base station; and performing first sidelink (SL) transmission on the basis of either the CG resource or the DG resource, wherein: the CG resource or the DG resource overlaps in the time domain; when the first SL transmission is initial transmission, the first SL transmission is performed on the basis of a resource from the CG resource or the DG resource, the resource being related to the first SL transmission; and when second SL transmission is retransmission, no second SL transmission is performed on the basis of a resource from the CG resource or the DG resource, the resource being related to the second SL transmission.
