MITIGATION OF TRANSMISSION ERRORS OF QUANTIZED CHANNEL STATE INFORMATION FEEDBACK IN MULTI ANTENNA SYSTEMS

摘要

Methods are disclosed for improving communications on feedback transmission channels, in which there is a possibility of bit errors. The basic solutions to counter those errors are: proper design of the CSI vector quantizer indexing (i.e., the bit representation of centroid indices) in order to minimize impact of index errors, use of error detection techniques to expurgate the erroneous indices and use of other methods to recover correct indices.

1. A wireless receiving device comprising:
at least one processing device configured to provide indices for a plurality of channel states; wherein at least one of the channel states corresponds to multiple input multiple output (MIMO) precoding information; the at least one processing device further configured to produce at least one codeword for transmission based on the provided indices; and a transmitter configured to transmit the at least one codeword to a wireless transmission device.
