Outside the active time, CSI information cann’t be updated . So CSI should be support in WUS in advance to DRX onduration to prepare for DL/UL data transmission.The periodic/semi-persistent CSI can be measured/reported earlier than Active Time. In current NR conclusion, if UE needs sleep for a long duration, UE will be outside Active Time for a long time. In R15, the most recent CSI measurement occasion occurs in DRX Active Time for CSI to be reported. And periodic/semi-persistent CSI reporting shall not be performed outside Active Time. So when UE wakes up, the periodic/semi-persistent CSI is possible to be out of date.
