Abstract
Various aspects of the disclosure provide a method of operating a user equipment (UE) to determine and report a throughput enhancing channel quality indicator (CQI) value when a physical channel between the UE and a base station is temporally uncorrelated. Reporting such CQI value may maximize the throughput of the channel when it remains temporally uncorrelated. In one aspect of the disclosure, the UE communicates with a base station utilizing a channel and determines that the channel is temporally uncorrelated. The UE further determines a plurality of CQIs in a first CQI reporting mode and computes the respective throughputs of the channel based on the plurality of CQIs. In addition, the UE selects a CQI of the plurality of CQIs corresponding to the highest throughput among the plurality of throughputs, and reports the selected CQI to the base station in a second CQI reporting mode while the channel remains temporally uncorrelated.
