ELECTRONIC DEVICE AND OPERATION METHOD FOR PERFORMING BACK-OFF ON BASIS OF SAR

Abstract: a method and an electronic device are provided, the electronic device includes a wireless fidelity (wifi) module for wifi communication, memory storing one or more computer programs, and at least one communication processor, for at least one cellular communication, communicatively coupled to the wifi module and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the at least one communication processor individually or collectively, cause the electronic device to, based on identifying that wifi module is in an off state, assign an overall specific absorption rate (sar) margin assigned to the electronic device for a first period to the at least one cellular communication, based on identifying that the wifi module is in an on state and a cumulative sar value consumed by the wifi module is less than or equal to a threshold value, assign a first amount of the sar margin assigned for the first period to the wifi communication and assign a remaining amount excluding the first amount to the at least one cellular communication, and based on identifying that the wifi module is in an on state and the cumulative sar value consumed by the wifi module exceeds the threshold value, assign a second amount of the sar margin assigned for the first period to the wifi communication, which is greater than the first amount, and assign a remaining amount excluding the second amount to the at least one cellular communication.
