发明名称 Grouping of users for MIMO transmission in a wireless communication system
摘要 Techniques for supporting MIMO transmission are described. User equipments (UEs) are classified into a first group of UEs to be scheduled individually and a second group of UEs that can be scheduled together. The classification may be based upon the number of transmit and receive antennas, sector loading, data requirements, long-term channel statistics, the number of UEs, etc. Channel quality indicator (CQI) information received from the UEs is interpreted in different manners depending on the groups to which the UEs belong. A single UE may be selected at a time from the first group or multiple UEs may be selected at a time from the second group for MIMO transmission. A MIMO transmission may be sent to a single UE in the first group or multiple UEs in the second group at rates selected based upon the CQI information.

主权项 1. An apparatus comprising: a processor configured to classify user equipments (UEs) into a plurality of groups comprising a first group and a second group, to interpret channel quality indicator (CQI) information received from UEs classified in the first group in accordance with a first interpretation, and to interpret CQI information received from UEs classified in the second group in accordance with a second interpretation, wherein the first group includes UEs to be scheduled individually for multiple-input multiple-output (MIMO) transmission, and wherein the second group includes UEs to be scheduled together for MIMO transmission; and a memory coupled to the processor.
