- the DRX Inactivity timer starts on the first symbol after PDCCH/PSCCH.
- the DRX Inactivity timer is set independently from the ON Duration of the DRX configuration and has no relationship.
- the DRX configuration initially configured for the UE may be changed to a new DRX configuration based on a trigger event.
- Triggering events are associated with available channel resources.
