20120069833 | CHANNEL STATE INFORMATION REPORTING FOR A SUCCESSIVELY DECODED, PRECODED MULTI-ANTENNA TRANSMISSION - Teachings herein provide reduced complexity channel state information (CSI) reporting for a successively decoded, precoded multi-antenna transmission. A wireless communication device reports CSI by forming, for each candidate transmission rank of the transmission, a sequence of codewords by iteratively adding codewords allowed for that rank to the sequence. At any given point in the sequence, the device adds the codeword expected to yield the highest individual information rate if decoded at that point in the sequence, considering the different rates possible under different precodings of the transmission. The device then computes, for each rank, a sum information rate across the codewords in the sequence formed for that rank, selects the rank having the highest sum information rate, and reports the selected rank along with the sequence formed for that rank. CSI reporting complexity is reduced because the device constrains its evaluation to only some of the possible decoding sequences. | 03-22-2012 |
