摘要： System and method for backoff correction of channel quality information (CQI). A correction factor is calculated based on a goodness measure such as packet error rate (PER). The selection of modulation and coding scheme (MCS) is made considering the channel quality information (CQI) adjusted by the correction factor. A meaningful goodness measure can be imposed if the goodness measure is very low. A different correction factor can be calculated for different confidence levels, MCSs and transmission modes.

摘要： A method for communication includes, in a first communication station, receiving from a second communication station via multiple antennas an input signal having a spectrum that occupies an initial set of spectral bins. An extended set of the spectral bins, which includes the initial set and one or more additional spectral bins, is defined. Based on the received input signal, respective beam steering matrices are computed for the spectral bins in the extended set, including the additional spectral bins. The output signal is generated over the extended set of the spectral bins, including the additional spectral bins, using the respective beam steering matrices. The output signal is transmitted from the first communication station via the multiple antennas.
