Method and apparatus for determining and reporting channel quality indicator for temporally uncorrelated channels

A user equipment (UE) configured to report channel quality in a wireless communication network, comprising:

• means for communicating with a base station utilizing a channel;
• means for determining that the channel is temporally uncorrelated;
• means for determining a plurality of channel quality indicators (CQIs) in a first QCI reporting mode and computing the respective throughputs of the channel based on the plurality of CQIs;
• means for selecting a CQI of the plurality of CQIs corresponding to the highest throughput among the plurality of throughputs;
• and
• means for reporting the selected CQI to the base station in a second CQI reporting mode while the channel remains temporally uncorrelated.

A user equipment (UE) configured to report channel quality in a wireless communication network, comprising:

• a memory comprising a channel quality reporting code;
• a communication interface configured to communicate with a base station utilizing a channel;
• and
• at least one processor operatively coupled with the memory and the communication interface,
• wherein the at least one processor when configured by the channel quality reporting code, comprises:
• a channel correlation block configured to determine that the channel is temporally uncorrelated;
• a channel quality indicator (CQI) determination block configured to measure a plurality of channel quality indicators (CQIs) in a first CQI reporting mode and compute the respective throughputs of the channel based on the plurality of CQIs;
• and
• a CQI selection block configured to select a CQI of the plurality of CQIs corresponding to the highest throughput among the plurality of throughputs, and report the selected CQI to the base station in a second CQI reporting mode while the channel remains temporally uncorrelated.

A computer-readable storage medium comprising channel quality indicator (CQI) reporting code for causing a user equipment (UE) to:

• communicate with a base station utilizing a channel;
• determine that the channel is temporally uncorrelated;
• determine a plurality of channel quality indicators (CQIs) in a first CQI reporting mode and compute the respective throughputs of the channel based on the plurality of CQIs;
• select a CQI of the plurality of CQIs corresponding to the highest throughput among the plurality of throughputs;
• and
• report the selected CQI to the base station in a second CQI reporting mode while the channel remains temporally uncorrelated.
