摘要

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.

說(shuō)明書(shū)

FIG. 8 shows a block diagram 800 of a device 805 that supports channel measurement techniques in discontinuous reception scenarios in accordance with aspects of the present disclosure. The device 805 may be an example of aspects of a device 705, or a UE 115 as described herein. The device 805 may include a receiver 810, a communications manager 815, and a transmitter 835. The device 805 may also include a processor. Each of these components may be in communication with one another (e.g., via one or more buses).

The receiver 810 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to channel measurement techniques in discontinuous reception scenarios, etc.). Information may be passed on to other components of the device 805. The receiver 810 may be an example of aspects of the transceiver 1020 described with reference to FIG. 10. The receiver 810 may utilize a single antenna or a set of antennas.

The communications manager 815 may be an example of aspects of the communications manager 715 as described herein. The communications manager 815 may include a DRX manager 820, a CSI manager 825, and a channel quality metric manager 830. The communications manager 815 may be an example of aspects of the communications manager 1010 described herein.
