Method for positioning user equipment in full-duplex wireless communication system and apparatus therefor

A base station performing UE position measurement in a wireless communication system supporting full-duplex communication, comprising:

• an RFU (radio frequency unit);
• and
• a processor, the processor configured to set a unit distance based on an IDI (inter-device interference) size to a first UE, the processor configured to determine at least one intersection region, which is overlapped between at least one first boundary configured according to at least one first relative distance based on the unit distance on the basis of the base station and at least one second boundary configured according to at least one second relative distance based on the unit distance on the basis of the first UE, as at least one or more position candidates for a second UE, the processor configured to assume a specific position candidate among the at least one or more position candidates as a position of the second UE and check whether or not at least one third boundary configured according to at least one third relative distance based on the unit distance on the basis of the assumed position of the second UE is overlapped with the intersection region,
• wherein the at least one first relative distance corresponds to distances of a plurality of the UEs which are measured by the base station according to the IDI size, wherein the at least one second relative distance corresponds to distances of a plurality of the UEs which are measured by the first UE according to the IDI size, and wherein the at least one third relative distance corresponds to distances of a plurality of the UEs which are measured by the second UE according to the IDI size.
