Abstract: A power control method and an apparatus for controlling power mode of a User Equipment (UE) operating on multiple frequencies are provided. The terminal includes a primary module for primary cell communication and a secondary module for secondary cell communication. The method includes receiving a secondary cell adding message for adding a secondary cell from a base station, checking data-related information on data communicated through at least one of the primary module and a secondary module, and determining a power mode of the secondary module based on the checking.

Abstract: An electronic device according to one embodiment of the present disclosure includes a conductive coil, a power generation circuit, and one or more processors operatively connected to the power generation circuit and may be configured to: compare an amount of transmission power to be supplied to a power reception device with designated threshold power amount, determine a designated frequency to be a frequency of a control signal for controlling the power generation circuit when the amount of transmission power is equal to or less than the designated threshold power amount, determine a phase of the control signal based at least in part on the amount of transmission power and/or the designated frequency when the designated frequency is determined to be the frequency of the control signal, transmit the control signal having the designated frequency and the phase to the power generation circuit to generate, based at least in part on the control signal, transmission power corresponding to the amount of transmission power, and supply the transmission power generated by the power generation circuit to the power reception device wirelessly via the conductive coil.
