Method and apparatus for providing efficient precoding feedback in a MIMO wireless communication system

摘要

Precoding feedback scheme based on Jacobi rotations to generate the feedback in the uplink. For a wireless communication system including a transmitter and a receiver. The system may use either a single codeword (SOW) or a double codeword (DCW). The precoding scheme is based on transmit beamforming (TxBF). Differential feedback is considered, with periodic non-differential feedback to avoid error accumulation or propagation due to differential processing.
