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

摘要

A multiple-input multiple-output (MIMO) scheme uses precoding and feedback in a wireless communication system including a transmitter and a receiver. The system may use either a single codeword (SCW) or a double codeword (DCW). The precoding scheme is based on transmit beamforming (TxBF). Combined differential and non-differential feedback with periodic resetting is considered. 7- CN CD. -cO 0 CD co CfoJ co co tc c coo _ pc Ln. c o mO
