In order to minimize the control signaling overhead associated with transmitting the CQI data from the mobile station to the base station in a wireless communication network that supports the MU-MIMO, the CQI for the MU-MIMO operation SU-MIMO CQI data, the mobile station geometry data, and the mobile station It is estimated based on the PMI (Precoding Matrix Index) data. More specifically, the base station maintains a knowledge pool (knowledge pool) for correlating the impact data of the geometry data and the interference pre-coder data to find out the degradation of the CQI value according to the transition to the MU-MIMO operation from the SU-MIMO operation the updating. Then, when the base station to switch to a MU-MIMO operation from the SU-MIMO operation, the base station queries the knowledge pool for predicting the deterioration of the CQI, and the conversion of the base for the degradation in each of the relevant mobile station before SU-MIMO CQI It is subtracted from the feedback data to predict the MU-MIMO CQI after switching on the mobile station.
