US 2022/0191965 A1 · METHOD AND APPARATUS FOR HANDLING SL DRX INACTIVITY TIMER IN WIRELESS COMMUNICATION SYSTEM

Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method performed by a first user equipment (UE) in a wireless communication system is provided. The method includes receiving, from a second UE, first sidelink control information (SCI) including scheduling information, receiving, from the second UE, second SCI based on the scheduling information, identifying whether the second SCI indicates a new transmission, and in case that the second SCI indicates the new transmission, starting a sidelink discontinuous reception (DRX) inactivity timer.
