摘要： A method and apparatus for feedback of channel information characterizing a wireless transmission between a base station and a mobile station over a communications channel. The method involves, at the base station, receiving a primary identifier identifying a cluster associated with a channel response generated by a mobile station, receiving a differential identifier identifying channel response member within the cluster identified by the primary identifier, and locating in a codebook of predetermined channel responses a predetermined channel response identified by the primary identifier and the differential identifier. The predetermined channel responses in the codebook are grouped in a plurality of clusters in accordance with a correlation criterion, each cluster including a plurality of predetermined channel response members. The method also involves generating a control signal for controlling transmissions to the mobile station in accordance with the located predetermined channel response. The method also involves, at the mobile station, determining a channel response for at least one carrier frequency received at the mobile station, and locating in a codebook of predetermined channel responses a predetermined channel response that is a closest match to the determined channel response, causing the mobile station to transmit a primary identifier identifying a cluster associated with the located predetermined channel response to the base station, and causing the mobile station to transmit a differential identifier identifying the located predetermined channel response member within the cluster identified by the primary identifier.

摘要： Methods and devices are provided for MIMO OFDM transmitter and receivers having odd and/even numbers of transmit antennas. Various methods for pre-coding information bits before space time coding (STC) are described for enabling transmission of information bits over all antennas. Methods of decoding received signals that have been pre-coded and STC coded are also provided by embodiments of the invention. Pilot patterns for downlink and uplink transmission between a base station and one or more wireless terminals for three transmit antenna transmitters are also provided. Variable rate codes are provided that combine various fixed rate codes in a manner that results in codes whose rates are dependent on all the various fixed rate codes that are combined.
