Abstract: Devices and methods for determining a wideband Channel Quality Indicator (wbCQI) and a plurality of sub-band Channel Quality Indicators (CQIs) for reporting to a network, including deriving a first metric for a wideband and each of a plurality of sub-bands from a received signal; converting the wideband first metric and the plurality of sub-band first metrics to a wideband CQI and a plurality of sub-band CQIs; determining a skewness of the plurality of sub-band CQIs to the wideband CQI by comparing each of the plurality of sub-band CQIs to the wideband CQI; modifying the wideband CQI when a negative skewness is determined and recomputing the plurality of sub-band CQIs based on the modified wideband CQI; and providing the modified wideband CQI and the plurality of recomputed sub-band CQIs to the network.
