Title:
無線通信システムにおけるMIMOためのCQIレポーティング
Document Type and Number:
Japanese Patent JP5108027
Kind Code:
B2
Abstract:
Techniques for determining and reporting channel quality indicator (CQI) information are described. A user equipment (UE) may determine a transmit power per channelization code, POVSF, based on the available transmit power and a designated number of channelization codes, e.g., by uniformly distributing the available transmit power across all transport blocks and all of the designated number of channelization codes. The UE may estimate SINRs of multiple transport blocks based on POVSF, determine CQI indices for the transport blocks based on the SINRs, and send the CQI indices to a Node B. The Node B may send multiple transport blocks to the UE based on the CQI indices. The Node B may send the transport blocks (i) with the designated number of channelization codes at POVSF or (ii) with a second number of channelization codes at POVSF, with the transport block sizes being scaled based on the designated and second numbers of channelization codes.
