17.1 RRC measurement events for UPH reporting

The RRC measurement events for UPH reporting allow the UE to perform measurements on UE Power Headroom (UPH) and signal measurement events when the UPH becomes larger or less than an absolute threshold respectively. The thresholds are configurable, as well as hysteresis, time-to-trigger, filter coefficient and pending time after trigger for each of the events.

17.2 Simultaneous Setup and Release of RABs and RBs

The simultaneous setup and release of RABs and RBs enhancement allows setup, release and reconfiguration of radio access bearers and radio bearers in the same RRC message.
