Method and device for controlling interference signal measurement in wireless communication system

A method for operating a first user equipment (UE) for measuring an interference signal in a wireless communication system, the method comprising:

• receiving, from a first base station (BS), timing information for measuring an interference signal generated by an uplink signal of a second UE communicating with a second BS;
• and
• measuring the interference signal generated by the uplink signal of the second UE, based on the timing information,
• wherein the timing information is determined based on a transmission and reception mode of the second BS.

A first base station (BS) for controlling interference signal measurement of a first user equipment (UE) in a wireless communication system, the first BS comprising:

• a transceiver;
• and
• a controller,
• wherein the controller is configured to:
• receive, from a second BS, information about a transmission and reception mode of the second BS,
• based on the information about the transmission and reception mode of the second BS, determine timing information used when the first UE measures an interference signal generated by an uplink signal of a second UE communicating with the second BS, and
• control to transmit, to the first UE, the timing information to enable the first UE to measure the interference signal.
