Abstract:
The present invention is designed to perform CQI measurement for adjacent cells without making the processes in the user terminal UE complex. A base station apparatus (eNodeB #1) provided in the serving cell has features of acquiring, from a base station apparatus (eNodeB #2) provided in an adjacent cell, the cell ID of the adjacent cell, and the position and transmission power of the CSI-RS, as parameters related to the CSI-RS of the adjacent cell, generating a broadcast signal including the above parameters related to the CSI-RS, and transmitting the generated signal to the user terminal (UE).
