SYSTEMS AND METHODS FOR TRELLIS CODED QUANTIZATION BASED CHANNEL FEEDBACK |
摘要 |
System and method embodiments are provided for Trellis Coded Quantization (TCQ) based channel feedback. The embodiments provide full channel state information with a short feedback size to a scheduler in order for the scheduler to apply advanced beamforming schemes, such as those designed in non-linear precoder methods. In an embodiment, a method in a station for providing channel feedback to a transmission point (TP) in a wireless system includes receiving a signal from the TP; estimating channel parameters for the signal; applying a TCQ scheme to the 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. |
