Method for measuring inter-device interference in wireless communication system supporting fdr transmission, and apparatus therefor

A method for transmitting a reference signal for inter-device interference (IDI) measurement by a user equipment (UE) in a wireless communication system supporting full duplex radio (FDR), the method comprising:

• mapping an interference reference signal for interference measurement to an uplink subframe according to interference reference resource configuration information;
• and
• transmitting the interference reference signal mapped to the uplink subframe to another UE,
• wherein an interference reference resource is located at the same position as that of an interference measurement resource, which is used by the another UE to measure interference.

A user equipment (UE) for measuring interference from another UE in a wireless communication system supporting full duplex radio (FDR), the UE comprising:

• a transceiver module configured to transmit and receive signals to and from a UE or a base station (BS);
• and
• a processor,
• wherein the processor is configured to control the transceiver module to receive an interference measurement resource in a measurement subframe and measure interference from a neighboring UE based on the interference measurement resource, and
• wherein data is not transmitted or transmitted with zero power on the interference measurement resource.
