A method and apparatus for feedback of channel information characterizing a wireless transmission between a base station and a mobile station. The method involves, at the base station, locating in a codebook of predetermined channel responses a predetermined channel response identified by: a primary identifier identifying a cluster associated with a channel response generated by a mobile station; and a differential identifier identifying channel response member within the cluster identified by the primary identifier. The predetermined channel responses 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. A method and apparatus for feedback of channel information characterizing a wireless transmission between a mobile station and a base station are also disclosed.
