Title:
METHOD AND DEVICE FOR SUPPORTING SIDELINK DRX ON BASIS OF MODE 1 CG RESOURCE IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2022/098138
Kind Code:
A1
Abstract:
An embodiment proposes a method for performing wireless communication by a first device. The method may comprise a step of receiving information related to a configured grant (CG) from a base station, the information related to the CG including information related to a hybrid automatic repeat request (HARQ) process ID for the CG, and period information of a resource related to the CG, and transmitting a first transport block to a second device at a first period on the basis of the period information and a first HARQ process ID. For example, on the basis that transmission of the first transport block fails, and the first HARQ process ID and a second HARQ process ID are the same, a discontinuous reception (DRX) timer related to the first transport block may be stopped at a second period related to the second HARQ process ID. For example, DRX related to the first transport block may include DRX between the first device and the base station and DRX between the first device and the second device.
