Method and apparatus for transmitting UE assistance information by UE supporting multiple USIM in wireless communication system

The present disclosure relates to a 5th-Generation (5G) or 6th-Generation (6G) communication system for supporting higher data transmission rates. A method performed by a user equipment (UE) supporting multiple universal subscriber identity modules (MUSIM) in a wireless communication system is provided. The method includes: receiving configuration information about MUSIM operation from a base station; transmitting a UE assistance information message to the base station in a case where the UE needs to leave a radio resource control (RRC) connection state using a first Universal Subscriber Identity Module (USIM) connection and a timer for switching the state is not running; and starting a timer for switching the state based on the configuration information on the MUSIM operation. 本公开涉及用于支持更高数据传输速率的第5代(5G)或第6代(6G)通信系统。提供了一种在无线通信系统中由支持多通用订户身份模块(MUSIM)的用户设备(UE)执行的方法。该方法包括：从基站接收关于MUSIM操作的配置信息；在UE需要离开使用第一通用订户身份模块(USIM)连接的无线电资源控制(RRC)连接状态并且用于转换状态的定时器没有运行的情况下，向基站发送UE辅助信息消息；以及基于关于MUSIM操作的配置信息启动用于转换状态的定时器。
