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

摘要

The present invention addresses the problem of appropriately estimating a coordinated cell that causes interference during CoMP transmission in a wireless base station device, in order to enable effective CoMP transmission. This wireless communication system comprises a plurality of wireless base station devices, and a user terminal (UE) configured to be capable of coordinated multipoint transmission and reception with the plurality of wireless base station devices, the user terminal (UE) having a transmission unit for transmitting information used to estimate a candidate cell causing interference during the coordinated multipoint transmission, and the wireless base station device having an estimation unit for estimating, based on the information, the candidate cell causing interference during the coordinated multipoint transmission.
