Abstract

An electronic device is provided. The electronic device includes a first antenna configured to transmit a first transmission signal having a first phase, a second antenna configured to transmit a second transmission signal having a second phase, a transceiver electrically connected to the first antenna and the second antenna, and a processor. The transceiver is configured to identify a first feedback transmission signal including part of the first transmission signal and a second feedback transmission signal including part of the second transmission signal and calculate a correlation for the first and second feedback transmission signals. The processor is configured to predict radiation power radiated from the electronic device based on at least the part of the correlation, control the transceiver to adjust at least one of the first phase or the second phase, and change the predicted radiation power to a predetermined value based on an operation for the adjustment.

Description

technical field [0001] The present disclosure relates to an electronic device and method for compensating signal phase. Background technique [0002] With the development of multiple-input multiple-output (MIMO) antenna communication technology, a user equipment (user equipment, UE) such as a mobile device may use two or more antennas. In order to improve the transmission performance, that is, to solve the reduction in total radiated power (TRP), call drop (call drop) and UE's transmission muting due to lack of power, beamforming Tx diversity (beamformingTx diversity, BFTD) technology has begun to be used in mobile communication systems. [0003] In the BFTD technique, two transmitted signals may be required to have the same phase. The UE for performing BFTD may include a single signal generating module in the communication module, and the single signal generating module may generate two transmission signals having the same phase. Two transmitted signals with the same pha...
