    Abstract: Various exemplary embodiments of the present disclosure relate to a device and a method for controlling a plurality of antennas in an electronic device. The electronic device may include: a plurality of antennas; a communication circuit configured to be connected to the plurality of antennas; and at least one processor, wherein the processor may be configured to: set a multi-antenna service using a second number of antennas; activate the second number of antennas among the plurality of antennas when a time to transmit channel state information comes; transmit channel state information on the second number of antennas to a network device; and switch to activate a first number of antennas among the plurality of antennas and the second number of antennas may include a greater number of antennas than the first number of antennas. Other exemplary embodiments are possible.

    Abstract: The present invention is for beam selection for communication, and an electronic device may include a housing, at least one antenna array including antenna elements disposed in the housing, or formed in part of the housing, at least one processor electrically or operatively connected with the antenna array, and configured to form a plurality of reception beams (rx beams) having different directions, using the antenna array, and a memory operatively connected with the processor. The memory may stores instructions for causing the processor to measure, by using the plurality of the rx beams, signal strength values of a plurality of tx beams transmitted from at least one base station and having different directions, generate measurement results of (the number of the rx beams)×(the number of the tx beams), and select one of a plurality of methods for selecting one beam pair from among the (the number of the rx beams)×(the number of the tx beams)-ary beam pairs, based at least in part on the measurement results.

    Abstract: A user equipment (UE) is provided. The UE supports D2D wireless communication and includes a communication module configured to communicate with at least one different UE, a non-transitory computer readable memory storage configured to store instructions, and at least one processor electrically connected to the communication module and the memory storage. The instructions, when executed by the UE, cause the processor to check whether an available first synchronization signal is detected, determine whether to operate as a first synchronization reference UE based on whether the first synchronization signal is detected, and transmit first system information comprising an intensity of transmission power and a second synchronization signal comprising a first synchronization identifier if the UE is determined to operate as the first synchronization reference UE.
