Abstract: A method, performed by a user equipment (UE) camping on a serving cell in a non-terrestrial network (NTN), for provisioning cell selection or reselection in the NTN, includes: receiving, by the UE from the serving cell, a first message comprising a first set of information; receiving, by the UE, a second message comprising a second set of information broadcasted by the serving cell, wherein the second set of information comprises information that is at least partially different from the first set of information; generating, by the UE, a cell selection or reselection list based on the first set of information and the second set of information, wherein the cell selection or reselection list comprises a plurality of candidate cells; and performing, by the UE, at least one network cell selection or reselection operation based on the cell selection or reselection list.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method comprises receiving, from a base station, a system information block (SIB) including slice information, identifying at least one cell for a slice service for the UE among a plurality of neighboring cells based on the slice information and camping on the at least one cell for the slice service.

Abstract: 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.

Abstract: A method for selecting a non-terrestrial network (NTN) cell by a user equipment (UE) is provided. The method includes receiving one or more system parameters from a serving NTN cell and a plurality of NTN neighbor cells, determining trajectory information associated with the plurality of NTN neighbor cells based on the one or more received system parameters, and selecting the NTN cell among the plurality of NTN neighbor cells to perform at least one of a cell reselection and a conditional hand over (CHO) based on the determined trajectory information associated with the plurality of NTN neighbor cells.

Abstract: A method for cell measurement by a user equipment (UE) in a non-terrestrial network (NTN) communication system is provided. The method includes camping to an NTN cell; receiving at least one parameter from the camped NTN cell; determining a rate of change (ROC) of signal strength of the camped NTN cell; determining whether a neighbor cell measurement criterion is met based on the at least one parameter and the ROC of the signal strength of the camped NTN cell; and initiating measurement for at least one neighbor cell based on the neighbor cell measurement criterion being met.

Abstract: 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.

Abstract: A method of handling an ongoing call performed by a UE in a wireless network is provided. The method includes initiating a voice over long term evolution (VoLTE) call in a 4th generation (4G) network, detecting that a 5th generation (5G) network entity has configured an inter radio access technology (I-RAT) measurement indicating a change from the 4G network to a 5G network based on identification of the 5G network by the UE, determining whether at least one of the UE or the 5G network does not support a voice over new radio (VoNR) call with a 5G cell in the 5G network, and performing one of delaying sending a measurement report until the VoLTE call is completed in response to determining that the at least one of the UE or the 5G network does not support the VoNR call, or sending the measurement report immediately for the 5G cell in response to determining that both the UE and the 5G network support the VoNR call.

Abstract: An offshore spill protection system includes a flare boom configured to connect to an offshore drilling rig. The flare boom is configured to flare at least a portion of hydrocarbons flowed from the offshore drilling rig to the flare boom. A liquid hydrocarbon capture system includes a plate configured to be spatially positioned relative to the flare boom. The plate is sized to collect at least unflared hydrocarbons in a liquid state that flow through the flare boom.
