In some cases, if the UE determines to measure CSI-RS while scheduled to be in a DRX inactive mode, the UE will determine an amount of time between the CSI-RS resource and a nearest scheduled DRX active period. FIGS. 4 through 6 illustrate different examples of different locations of the CSI-RS resource within the scheduled DRX inactive mode.
FIG. 4 illustrates an example of a DRX cycle with a limited active mode portion 400 that supports channel measurement techniques in discontinuous reception scenarios in accordance with aspects of the present disclosure. In some examples, DRX cycle with additional limited active mode portions 400 may implement aspects of wireless communications system 100 or 200. In this example, a CSI-RS configuration may provide CSI-RS arrivals 405 at periodic intervals, as indicated with CSI-0 410-a and CSI-1 410-b. In some cases, CSI-1 410-b may be an example of a first reference signal for a first channel measurement at the UE, and CSI-0 410-a may be an example of a prior reference signal.
