As discussed above, CSI-RS measurements and reporting timelines may be set independently of DRX timelines, and all three timelines may run asynchronously. Because timelines for CSI-RS and DRX may be different, scenarios such as in the example of FIG. 3 may occur, in which periodic CSI-RS resources 315 fall during DRX inactive 305 periods where the UE is not required to measure the reference signal transmissions. Because channel state feedback reports that are transmitted using measurement report 320 resources use measured CSI-RS results, this means that CSI-RS measurements may be stale (e.g., on the order of seconds or more). During this time, especially in mobility scenarios, the UE's channel quality may have changed, and the UE would be unable to inform the network of the updated channel quality.
