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. Accordingly, the embodiments herein disclose a method for handling a timer operation in a wireless communication system. The method includes receiving, by a UE, a signaling message from a base station. The signaling message includes an information about acquired COT of the base station. Further, the method includes indicating, by the UE, about the acquired COT to a MAC layer from a physical layer.
