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.

In the method, a receiver determines a corresponding codebook from a multi-codebook including multiple codebooks according to a location of a resource block, selects a corresponding codeword index from the determined codebook and transmits the index to a transmitter; the transmitter determines the corresponding codebook from the multi-codebook including multiple codebooks according to the location of the resource block where transmission data is to be transmitted, selects a corresponding codeword from the determined codebook according to the codeword index and performs pre-coding for the transmission data with the selected codeword.
