摘要
A method for providing channel feedback includes receiving a signal from a transmission point (TP), estimating channel parameters from the signal as received, mapping the estimated channel parameters to a trellis in accordance with a Trellis Coded Quantization (TCQ) scheme, and applying a Viterbi algorithm (VA) to the trellis to generate quantized channel parameters, the quantized channel parameters including a plurality of samples. The method also includes identifying samples of the estimated channel parameters associated with samples of quantized channel parameters having quantization errors above a predetermined threshold, generating indicators in accordance with the samples having the quantization error above the predetermined threshold, and transmitting, by the RP, the quantized channel parameters and the indicators to the TP.
