Abstract
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.
Claims18
A wireless device comprising:
- receiver circuitry operable to receive an encoded sequence on an uplink feedback channel, the encoded sequence received in a number of symbols that is based on a number of bits available for transmission on the uplink feedback channel;
- and
- transmitter circuitry operable to transmit a downlink channel based on the encoded sequence.
A method implemented in a wireless device, the method comprising:
- receiving an encoded sequence on an uplink feedback channel, the encoded sequence received in a number of symbols that is based on a number of bits available for transmission on the uplink feedback channel;
- and
- transmitting a downlink channel based on the encoded sequence.
