Channel measurement techniques in discontinuous reception scenarios
摘要
說明書
In some examples, the DRX manager 910 may maintain channel measurement components (e.g., one or more power amplifiers, reference signal sequence detection components, channel estimation components, etc.) of the UE in an ON state and deactivate PDCCH decoding components (e.g., de-mapping components, de-interleaving components, digital Fourier transform (DFT) components, baseband decoding components, etc.) following an ON-duration of the discontinuous reception cycle that is prior to the first channel measurement. In some examples, the DRX manager 910 may deactivate, responsive to performing the first channel measurement, the channel measurement components.
In some examples, the DRX manager 910 may transition channel measurement components and PDCCH decoding components of the UE to an inactive state following an ON-duration of the discontinuous reception cycle that is prior to the first channel measurement. In some examples, the DRX manager 910 may transition the channel measurement components to an ON state based on the channel measurement schedule associated with the first channel measurement. In some examples, the DRX manager 910 may transition the PDCCH decoding components to the ON state for a subsequent ON-duration. In some cases, the predetermined period is based on a preconfigured time duration. In some cases, a duration of the predetermined period is based on a magnitude of the change in the channel quality metric. In some cases, a duration of the predetermined period is longer for a smaller magnitude of change in the channel quality metric, and is shorter for a larger magnitude of change in the channel quality metric. In some cases, the channel measurement components are maintained in the ON state after expiration of the ON-duration based on the scheduled CSI measurement being within a predetermined time from the expiration of the ON-duration.
