ELECTRONIC DEVICE, AND METHOD BY WHICH ELECTRONIC DEVICE TRANSMITS REFERENCE SIGNAL

WIPO Patent Application WO/2022/164188

A1

An electronic device according to various embodiments comprises: a communication processor; at least one radio frequency integrated circuit (RFIC); a first antenna group including a plurality of antennas for transmitting or receiving data of a first communication network; and a second antenna group including a plurality of antennas for transmitting or receiving data of a second communication network, wherein the communication processor can control to: receive, from a first base station corresponding to the first communication network or a second base station corresponding to the second communication network, first information related to the transmission time of a reference signal transmitted to the first base station; receive, from the second base station, second information related to the time at which the data of the second communication network is transmitted and received; and select a first antenna adjacent to a second antenna from among the plurality of antennas of the first antenna group at the time at which uplink data is transmitted to the second base station through a second antenna of the second antenna group on the basis of the received first information and the received second information, so as to transmit the reference signal to the first base station.
