Patent ID: 8576896

Claim:
A method for wireless communications, comprising: providing an indication of a preference by a wireless device of one or more transmission channels of a Multiple Input Multiple Output (MIMO) communication system, the preferred one or more transmission channels being selected by the wireless device based at least in part on a channel state information, and the indication comprising a signal comprising log 2 (N) bits in which N comprises a number of transmitting channels in the MIMO communication system; receiving channel output at the wireless device, the received channel output corresponding to a transmitted portion of an Orthogonal Space Time Code (OSTC) codeword, the OSTC codeword conveying symbols, the OSTC codeword comprising the transmitted portion and a non-transmitted portion, wherein the non-transmitted portion comprises a null value corresponding to the channel preference, the null value corresponding to the portion of received channel output having no transmission activity during a timeslot; determining estimated channel output corresponding to the non-transmitted portion of the OSTC codeword; reconstructing the OSTC codeword using both the received channel output and the estimated channel output; and decoding the symbols using the reconstructed OSTC codeword.
