Abstract: Methods, apparatuses, and systems are disclosed for enhancing timing relationships in non-terrestrial networks (NTNs), e.g., by managing timing offset values and intelligently handling reporting failure relating to timing information reporting. To accommodate increased propagation delay in NTNs, a user equipment (UE) may supplement its timing advance (TA) value with component values representing roundtrip times to the satellite. The UE may maintain both open-loop and closed-loop portions of the TA value, and may report the TA value, or components thereof, to the network for timing synchronization. Methods and systems are also disclosed for failure handling in this reporting process.

Abstract: Apparatuses, systems, and methods for enhancement in NTN mobility. A cellular base station may serve as a source base station of a handover procedure from the source base station to a target non-terrestrial network (NTN) base station. The cellular base station may configure a parameter associated with the target NTN base station in a handover command, the parameter being related to NTN mobility, and send the handover command to a wireless device for use by the wireless device during the handover procedure. The wireless device may receive the handover command from the cellular base station, and perform the handover procedure using the parameter associated with the target NTN base station.

Abstract: A user equipment (UE) is configured to decode a system information block (SIB). The UE receives a first signal, wherein the first signal includes a first individual system information block (SIB) segment of a SIB, receives a second signal, wherein the second signal includes a second individual SIB segment of the SIB, reassembles the SIB using first SIB segment and the second SIB segment and decodes the contents of the SIB.

Abstract: Apparatuses, systems, and methods for non-small data transmission (non-SDT) dedicated radio bearer (DRB) handling while in a radio resource control (RRC) inactive state. A wireless device may determine, while operating in the RRC inactive state, that non-SDT data is available for transmission on a non-SDT DRB and determine, based on one or more conditions, to transmit, to a base station, non-SDT data arrival information during an SDT procedure. The one or more conditions may be associated with arrival time of the non-SDT data and/or an amount of non-SDT data to be transmitted. The arrival time may be relative to arrival of SDT data, initiation of an SDT procedure, and/or initiation of a subsequent transmission period of an SDT procedure.

IPC: H04W68/08

Abstract: Techniques discussed herein may enable effective cell identification and paging within a non-terrestrial network (NTN). A base station may map logical cell identifiers, corresponding to satellites, to physical cell identifiers, corresponding to physical or geographic cells. The techniques enable cell identification and paging in both Earth-fixed cell scenarios and Earth-moving cell scenarios, and in scenarios where the satellite moves between countries.

Abstract: Techniques discussed herein facilitate cell selection and/or reselection in scenarios involving one or more Non-Terrestrial Network (NTN) cells. One example embodiment is a User Equipment (UE) device comprising a processor configured to perform operations comprising: determining one or more suitable cells for one of a cell selection procedure or a cell re-selection procedure, wherein the one or more suitable cells comprise a first cell associated with a satellite of a NTN; determining a ranking for each cell of the one or more suitable cells, wherein the ranking for the first cell is based at least in part on a location of the UE, ephemeris data of the satellite, and one or more additional parameters; selecting a highest ranked cell of the one or more suitable cells based on the determined rankings for each cell of the one or more suitable cells; and camping on the highest ranked cell.
