Electronic device optimizing current consumption by considering a wake up signal and operating method thereof

Abstract

An electronic device and a method of operating the same are provided. The electronic device includes an antenna module, a first communication module configured to transmit and receive a signal to and from a base station through the antenna module, memory storing one or more computer programs, and one or more processors communicatively coupled to the first communication module, the antenna module, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors, cause the electronic device to identify a reception timing of a wake up signal based on wake up signal configuration information received from the base station, select one of transmission beams of the base station and one of reception beams of the electronic device as a beam pair, measure a reception strength of the selected transmission beam of the beam pair using the selected reception beam of the beam pair in a synchronization signal block (SSB) burst period before the reception timing arrives, stabilize a synchronization loop including at least one radio frequency (RF) element through an SSB of the selected transmission beam of the beam pair, detect the wake up signal transmitted from the base station at the reception timing, and determine whether to perform a beam searching operation based on the measured reception strength and a reception strength of the wake up signal.
