摘要： A base station apparatus includes a correction unit for correcting a CQI reported from a user apparatus and a scheduler for scheduling based on the corrected CQI. The correction unit uses a correction table to correct the CQI such that if the reported CQI is poor, the CQI is slightly reduced, and otherwise, the CQI is significantly reduced. One method of generating the correction table includes deriving a first SINR in consideration of the number of interference users less than (n−1) and a second SINR in consideration of the number of interference users equal to (n−1) to explore a distribution of the second SINR to the first SINR. In this method, correspondence between the first SINR and the second SINR is determined based on the distribution to generate the correction table.

摘要： A base station receives channel state information corresponding to each of spare coordinated groups from each of user devices. A first group includes a plurality of coordinated groups arranged in advance. The spare coordinated groups corresponding to each user device are such as selected from the first group and include at least a service sector of best channel quality obtained measurement by the user device. The base station specifies a user device group corresponding to each of coordinated groups contained in each of coordinated group patterns. The user device group corresponding to the coordinated group is formed of user devices having the coordinated group in their spare coordinated groups. The base station uses channel state information reported from the user devices of the user device group corresponding to the coordinated group as a basis to perform user scheduling on the coordinated group.
