Abstract
Provided is a radio base station apparatus capable of selecting an optimal modulation and coding scheme for each transmission stream easily. The radio base station apparatus has a CQI information decoder (101) configured to decode CQIs of plural downlink transmission streams and an MCS selector (102) that has an N-dimensional table (two-dimensional reference table (1021)) in accordance with the number N of downlink transmission streams where combinations of modulation and coding scheme between the plural downlink transmission streams are defined in accordance with each of the CQIs of the downlink transmission streams and is configured to select from the combinations of modulation and coding scheme for the downlink transmission streams based on each of the CQIs of the downlink transmission streams decoded by the CQI information decoder (101).
