Abstract
Methods, systems, and devices for wireless communications are described for configuring a user equipment (UE) for reference signal measurement while operating according to a discontinuous reception (DRX) configuration. The DRX configuration may include periodic DRX ON-durations, during which the UE is to be in an active mode for reception and transmission of signals, and between which the UE may transition to a low-power inactive mode. One or more reference signals may be scheduled for transmission by the base station during periods in which the UE may be in the inactive mode, and the UE may skip monitoring one or more of the reference signals while in the inactive mode. For one or more reference signal occasions, the UE may determine, based at least in part on a change in a channel quality metric, to be in a limited active mode in order to measure the reference signal.
