Title:
無線通信システムにおけるMIMO伝送のためのユーザーのグループ分け
Document Type and Number:
Japanese Patent JP5497218
Kind Code:
B2
Abstract:
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.
