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.

Abstract translation: 本公开的各个方面提供了当UE和基站之间的物理信道在时间上不相关时操作用户设备（UE）以确定和报告吞吐量增强信道质量指示符（CQI）值的方法。 报告这样的CQI值可以使信道的时间上不相关的吞吐量最大化。 在本公开的一个方面，UE利用信道与基站进行通信，并确定信道在时间上不相关。 UE进一步在第一CQI报告模式中确定多个CQI，并且基于多个CQI来计算信道的相应吞吐量。 另外，UE在多个吞吐量中选择对应于最高吞吐量的多个CQI的CQI，并且在第二CQI报告模式中将所选择的CQI报告给基站，同时信道保持在时间上不相关。
