Title:
WIRELESS BASE STATION APPARATUS AND MODULATION AND CODING SCHEME SELECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2010/098168
Kind Code:
A1
Abstract:
A wireless base station apparatus which simply selects the optimum modulation and coding scheme for each transmission stream. The wireless base station apparatus is provided with: a CQI information decoding unit (101) which decodes the CQIs of a plurality of downlink transmission streams; and an MCS selection unit (102) which has an N-dimensional table (two dimensional reference table (1021)) having predetermined combinations of modulation and coding schemes between the plurality of downlink transmission streams corresponding to the CQIs of the downlink transmission streams, and which selects a combination of modulation and coding schemes between the plurality of downlink transmission streams based on the CQIs of the downlink transmissions streams decoded by the CQI information decoding unit (101). The N-dimensional table corresponds to the number (N) of downlink transmission streams.
