B.2.7 Additional DRX active time p. 77
This clause captures evaluation results for additional DRX active time.
- ZTE evaluated the extension for additional active time if UE does not receive UE specific data scheduled by a PDCCH CRC scrambled by the XR-specific RNTI within current active time.
- OPPO evaluated additional On Duration triggered by dynamic signaling such as a DCI to receive data that arrives after the On Duration expires.
- Nokia evaluated the Extension of Active Time (EAT) to extend DRX active time if XR frame does not arrive before the On Duration timer expires.
- vivo compared the additional DRX active time and R17 PDCCH monitoring adaptation scheme.
