Abstract
Providing adaptive channel state feedback (CSF) reports in discontinuous reception (DRX) scenarios in a power-efficient manner. The described algorithm may be able to make adaptive decisions to carry over the CSF from previous DRX cycles based on channel conditions, DRX cycle length, and/or the requirements of CSF reporting for current DRX cycle. The proposed approach can allow for more efficient power consumption related to CSF reports in DRX scenarios where new CSF reports have little or no impact to throughput.
