Title:
METHOD AND DEVICE FOR PERFORMING SL DRX ON BASIS OF MOBILITY BY TERMINAL IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2022/154413
Kind Code:
A1
Abstract:
An embodiment proposes a method for performing wireless communication by a first device. The method can comprise the steps of: establishing radio resource control (RRC) connection with a second terminal; establishing SL communication with the second terminal on the basis of first sidelink discontinuous reception (SL DRX) configuration; receiving an RRC reconfiguration message comprising second SL DRX configuration from a first base station, on the basis of which a first terminal performs handover from the first base station to a second base station, wherein the second SL DRX configuration is transmitted to the first base station from the second base station; and establishing SL communication with the second terminal on the basis of the second SL DRX configuration.
