1. A method in a station for providing channel feedback to a transmission point (TP) in a wireless system, the method comprising: receiving a signal from the TP; estimating channel parameters for the signal; normalizing the estimated channel parameters into a predefined range according to a transmission power of the TP, a receiver power of the station, and path loss information; applying a Trellis Coded Quantization (TCQ) scheme to the normalized estimated channel parameters to map the channel estimate parameters to trellis codes; and transmitting full channel state information to the TP, wherein the full channel state information comprises output of a Viterbi algorithm (VA) corresponding to the trellis codes.
