摘要： Embodiments disclosed herein relate to dynamic methods and systems for reading System Information Block 19 (SIB19) for maintaining Uplink Synchronization (UL Sync) and updated cell information during Non-Terrestrial networks (NTN) connectivity. The methods include a dynamic algorithm to reacquire SIB19 by considering different factors of UE's current status such as Radio Resource Control (RRC) states (idle/inactive/connected), SI periodicity of SIB19, emergency call status and UL Sync validity timer duration. The methods include monitoring of the UE status periodically and dynamically executing the algorithm to decide the time instance and periodicity to re-acquire SIB-19 based on UE current status. The methods include evaluating the UE condition on each SIB periodicity, and determining the next time period and periodicity to read SIB19.

摘要： A method and/or system for initiating one of a plurality of cell transition activities for a UE supporting multicast and broadcast services (MBS). The technique may include identifying, by the UE, one or more candidate cells available for one of the plurality of cell transition activities for the UE. The technique may include identifying, by the UE, at least one candidate cell among the one or more candidate cells that support MBS. The technique may include initiating, by the UE, one of the plurality of cell transition activities for the UE using the at least one candidate cell.
