Abstract: A user equipment (UE) may receive a downlink message from a non-terrestrial network (NTN) which may include one or more sets of terrestrial network (TN) cell reselection information. The one or more sets of TN cell reselection information may further include location information corresponding to one or more cells of the TN. The UE may determine its location and, in response to receiving the downlink message, compare its location to the location information corresponding to the one or more cells of the TN. The UE may then select, based on the comparison, a set of the one or more sets of TN cell reselection information and further perform a cell reselection procedure based on the selection.

Abstract: Techniques, described herein, include solutions for managing hybrid automatic repeat request (HARQ) processes and communications for non-terrestrial networks (NTNs) (e.g., a wireless communication network that includes a satellite network component). A user equipment (UE) may connect to an NTN and determine hybrid automatic repeat request (HARQ) capabilities regarding NTNs. The UE may also communicate a HARQ disablement message to the NTN and communicate with NTN without HARQ procedures. The HARQ disablement message may provide the HARQ disablement capabilities of the UE and/or be a request for the network to disable HARQ. The HARQ disablement message may include a radio resource control (RRC) reconfiguration message and may address HARQ disablement per logical channel identifier (LCID) or dedicated radio bearer (DRB).

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: This disclosure relates to techniques for supporting multiple Quality of Service flows for a service data flow in a wireless communication system. The service data flow may include multiple categories of data with different Quality of Service parameters. Separate Quality of Service flows may be established for each of the categories of data with different Quality of Service parameters. A cellular network and a wireless device communicating data for the service data flow may apply packet detection rules or packet filters to determine on which Quality of Service Flow to communicate data packets of the service data flow, and may communicate the data packets accordingly.

Abstract: The functions of user equipment (UE), radio access network (RAN) devices, and core network (CN) devices in circumstances where a UE is expected to experience discontinuous coverage are described herein. A UE may send a CN a non-access stratum (NAS) message including a release request indicating that a UE is leaving coverage and assistance information. The CN may interrupt paging of the UE and resume the paging according to the assistance information. A UE may enter a low power usage mode upon leaving coverage, and may use one or more timers to determine when to check for coverage and send a mobility update message corresponding to the low power usage mode. A base station may receive, from a UE, a radio resource control (RRC) message comprising a release request and assistance information, send an RRC release message to the UE in response, and forward the assistance information to the CN.
