PROBLEM TO BE SOLVED: To provide techniques for supporting MIMO transmission.SOLUTION: User equipment (UE) is classified into a first group of UE to be scheduled individually and a second group of UE that can be scheduled together (312). The classification is based upon the number of transmit and receive antennas, sector loading, data requirements, long-term channel statistics, and the number of pieces of UE. Channel quality indicator (CQI) information received from the UE is interpreted in different manners depending on the groups to which the UE belong. For MIMO transmission, single UE is selected at a time from the first group (314), or multiple UE is selected at a time from the second group (316). A MIMO transmission is sent to single UE in the first group or multiple UE in the second group, at rates selected based upon the CQI information (318). |
