Title:
METHOD AND DEVICE FOR OPERATING TX UE RELATED TO SL DRX CAPABILITY OF BASE STATION IN SIDELINK DRX IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/153894
Kind Code:
A1
Abstract:
One embodiment relates to a method for operating a transmitting user equipment (TX UE) related to sidelink discontinuous reception (SL DRX) in a wireless communication system, the method comprising: a step in which the TX UE establishes a PC5 connection with a receiving user equipment (RX UE); a step in which the TX UE receives information requesting sidelink capability from the RX UE; a step in which the TX UE transmits information related to sidelink capability to the RX UE, wherein the information related to the sidelink capability informs the RX UE of whether the TX UE supports the SL DRX, and on the basis of a serving base station of the TX UE not supporting the SL DRX, the information related to the sidelink capability informs the RX UE that the TX UE does not support the SL DRX.
