Electronic device, and method by which electronic device transmits reference signal

An electronic device comprising:

• at least one communication processor comprising processing circuitry;
• at least one radio frequency integrated circuit (RFIC) connected to the at least one communication processor;
• and
• a plurality of antennas connected to the at least one RFIC to transmit or receive data corresponding to at least one of a first communication network or a second communication network,
• wherein the at least one communication processor is configured, individually or collectively, 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 regarding a transmission timepoint of a reference signal transmitted to the first base station,
• receive, from the second base station, second information regarding a timepoint at which data of the second communication network is transmitted or received, wherein the first communication network supports a first access technology and the second communication network supports a second access technology that is a different from the first access technology;
• identify a timepoint at which the reference signal is to be transmitted through an antenna configured to transmit a signal corresponding to the second communication network, among the plurality of antennas configured to transmit the reference signal, based on the received first information and the received second information,
• configure a timepoint at which a reference signal is to be transmitted through the antenna to correspond to a timepoint at which uplink data corresponding to the second communication network is transmitted;
• and
• control to transmit the reference signal to the first base station through the antenna, based on the configured timepoint at which the reference signal is transmitted.

A method for transmitting a reference signal by an electronic device comprising a communication processor, at least one radio frequency integrated circuit (RFIC) connected to the communication processor, a first antenna group comprising a plurality of antennas connected to the at least one RFIC to transmit or receive data of a first communication network, and a second antenna group comprising a plurality of antennas connected to the at least one RFIC to transmit or receive data of a second communication network, wherein the first communication network supports a first access technology and the second communication network supports a second access technology that is a different from the first access technology, the first antenna group and the second antenna group being distinct from one another, the method comprising:

• receiving, from a first base station corresponding to the first communication network and/or a second base station corresponding to the second communication network, first information regarding a transmission timepoint of a reference signal transmitted to the first base station;
• receiving, from the second base station, second information regarding a timepoint at which data of the second communication network is transmitted and/or received;
• and
• selecting a first antenna relatively spaced apart from a second antenna, among the plurality of antennas of the first antenna group, and transmitting, at a timepoint at which uplink data is transmitted to the second base station through the second antenna of the second antenna group, the reference signal to the first base station via the selected first antenna, based on the received first information and the received second information.
