WIRELESS COMMUNICATION SYSTEM, WIRELESS BASE STATION DEVICE, USER TERMINAL, AND WIRELESS COMMUNICATION METHOD

摘要

The present invention is designed to enable a radio base station apparatus to adequately estimate a coordinated cell to cause interference upon CoMP transmission, and effectively execute CoMP transmission. A radio communication system, according to the present invention, includes a plurality of radio base station apparatuses, and a user terminal (UE) that is configured to be able to perform coordinated multiple point transmission/reception with the plurality of radio base station apparatuses, where the user terminal (UE) has a transmission section that transmits information to use to estimate a candidate cell to be an interference cell upon coordinated multiple point transmission, and the radio base station apparatus has an estimation section that estimates a candidate cell to be an interference cell upon coordinated multiple point transmission based on the information.
