Abstract

An electronic device according to an example embodiment includes: at least one wireless communication module comprising communication circuitry configured to transmit and receive a wireless signal, at least one processor operatively connected to the at least one wireless communication module, and a memory electrically connected to the processor and configured to store instructions executable by the processor, wherein, in response to the instructions being executed by the processor, the processor may be configured to: determine whether there is a target wake time (TWT) parameter for a TWT service, determine a time-averaged specific absorption rate (TAS) backoff regulation value for a time window based on the TWT parameter, and control the at least one wireless communication module to perform communication during the time window based on the TAS backoff regulation value and the TWT parameter.
