Channel measurement techniques in discontinuous reception scenarios

In some cases, the UE may extend the duration of an ON-duration of the DRX cycle before or after the scheduled ON-duration in order to be in the limited active mode for the reference signal transmission. In other cases, the UE may transition to the inactive mode, transition to the limited active mode for the reference signal measurement, and then transition back to the inactive mode until the start of the next scheduled active mode of the DRX configuration. In some cases, the UE may determine whether to extend an ON-duration or wake up from an inactive mode to the limited active mode based at least in part on an amount of time between a start or end of a scheduled ON-duration and the scheduled reference signal transmission. In some cases, when the UE is set to be in the limited active mode, the UE may power down or deactivate components associated with channel decoding (e.g., physical downlink control channel (PDCCH) decoding) while activating components to receive the reference signal transmission. For example, in some cases the UE may turn on a front end of a receive chain to capture samples of the reference signal and turn off baseband decoding components of the receive chain. Such a limited active mode may thus provide power to components associated with reference signal measurements, but allow other components to be deactivated in order to provide reduced power consumption during such measurements relative to power consumption during a scheduled ON-duration in which channel decoding components are active.
