Patent attributes
A method of a UE is provided. The method includes receiving, from a base station, first information of a first timer of a bandwidth part inactivity associated with a bandwidth part of a primary cell (PCell) and second information of a second timer of a bandwidth part inactivity associated with a bandwidth part of a secondary cell (SCell), identifying that a random access procedure is initiated on the PCell or the S cell, stopping the first timer, if running, in response to identifying that the random access procedure is initiated on the Pcell, and stopping the first timer and the second timer, if running, in response to identifying that the random access procedure is initiated on the SCell. The method relates to a communication method and system for converging a 5th-Generation communication system for supporting higher data rates beyond a 4th-Generation system with a technology for Internet of Things (IoT).
