Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system or networks beyond 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. A method of a User Equipment (UE) in a wireless communication system, the method comprising: receiving, from a base station, configuration information on reporting assistance information associated with an overheating; detecting the overheating; and transmitting, to the base station, the assistance information including first information for controlling a bandwidth associated with at least one of a first frequency range or a second frequency range based on UE's preference, wherein a first frequency corresponding to the first frequency range is smaller than a second frequency corresponding to the second frequency range.
