Precoding for segment sensitive scheduling in wireless communication systems

摘要

A wireless communication apparatus comprises a processor configured to decode signals that are received over two or more subcarriers of a segment of subcarriers, which is one of a plurality of segments of subcarriers available for communication, and to provide precoding information for at least one segment; and a transmitter configured to transmit the precoding information, wherein the transmitter is configured to transmit the precoding information on a feedback channel associated with the at least one segment. The precoding feedback is reported in multiple channel quality indication (CQI) channels and the number of used CQI channels depends on the number of available codes.
