摘要： A variable sub-carrier mapping method comprising steps of: applying different bit interleaving schemes to different transmissions of a hybrid automatic retransmission request (HARQ) process in side of transmitter; and in the side of the transmitter, modulating symbols onto sub-carriers for transmitting. Different transmissions in one HARQ process adopt different bit interleavers or different symbol-to-sub-carrier mapping methods so as to realize that the same bit of different transmissions in one HARQ process is transmitted via different sub-carriers. Therefore, the system achieves the frequency diversity gain and reduces the probability of failure of HARQ transmission caused by that some bits are always transmitted via the sub-carrier with the same deep fading. In this way, the average HARQ retransmission times can be reduced and the system throughput can be improved.

摘要： A method for a UE reporting a CQI comprising steps of: obtaining a total number M of CQI report sub-bands in a system and a number N of CQI report sub-bands needed to be reported; measuring channel qualities of all sub-bands and according to the measurement result, determining N CQI report sub-bands needed to be reported and corresponding CQI values; sending a L-bit long sequence to a base station for indicating the sub-bands that need to be reported; sending CQI values corresponding to the sub-bands need to be reported to the base station. The present invention uses comparatively shorter bit sequence to indicate CQI report sub-bands needed to be reported and reduces the number of information bits necessary for CQI report sub-bands and also reduces the number of information bits corresponding to the CQI values in the CQI report sub-bands.
