Adaptive generation of channel quality indicators (CQIs) based on a current communication scenario

摘要

Adaptive generation of channel quality indicators based on a current communication scenario. A plurality of sets of channel quality indicator information may be stored for each of a plurality of UE communication scenarios. The information may be usable in generating a channel quality indicator. During operation of the UE, a current communication scenario of the UE may be determined. A first set of channel quality indicator information may be selected based on the determined current communication scenario being experienced by the UE. At least one channel quality indicator may be determined based on the selected first set of channel quality indicator information. Finally, the channel quality indicator may be provided to a base station.

1. A user equipment (UE) device, the UE device comprising:
an antenna for performing wireless communications with a base station; a memory which stores a plurality of sets of communication scenario information for each of a plurality of UE communication scenarios, wherein each of the stored plurality of sets of communication scenario information is based on two or more of receiver type, multiple input-multiple output (MIMO) scheme, and amount of Doppler shift, wherein each set of communication scenario information is useable in generating a channel quality indicator for a respective communication scenario; a processor configured to:
determine a current communication scenario of the UE device during operation of the UE, wherein determining the current communication scenario is based on the two or more of receiver type, MIMO scheme, and amount of Doppler shift;select a first set of communication scenario information from the plurality of sets of communication scenario information based on the determined current communication scenario of the UE device;determine a current channel estimation for the UE device; andgenerate at least one channel quality indicator based on the selected first set of communication scenario information and the current channel estimation, wherein the current channel estimation is used to generate the channel quality indicator for each of the plurality of UE communication scenarios; wherein the UE device is configured to transmit the channel quality indicator to a base station.
