Abstract: The present application relates to devices and components including apparatus, systems, and methods for performing measurements before a radio link failure. In an example, a condition is detected by a UE in advance of a time point in which a non-terrestrial network (NTN) node is to stop providing service to the UE. The condition can be a timing-based condition related to, for example, t-service, a location-based condition related to, for example, a reference location, a coverage hole, and/or a timer condition. The UE can perform, in advance of the time point, a radio resource management (RRM) measurement in an attempt to measure a neighbor cell based on the condition.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for network assisted side-link resource configuration for unicast and/or multi-cast/groupcast communications in V2X networks. A UE may, after establishing an RRC connection with a base station, transmit, to the base station, V2X connection information. The V2X connection information may include a V2X identifier associated with the UE and a V2X identifier associated with a target UE. The UE may receive, from the base station, a side-link configuration for data transmission with the target UE. The side-link configuration may include a resource allocation defined in time and frequency (e.g., a transmit/receive pool). The UE may communicate with the target UE using the resource allocation included in the side-link configuration.

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.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to resume a connection. To resume the connection, the UE may transmit a fully protected connection resume message, e.g., which may include protection for a resume cause field.

Abstract: An approach is described for a base station to generate a first message and a second message. The base station transmits the first message and the second message to a user equipment (UE). The first message is associated with a cell supported by the base station and includes a first public land mobile network (PLMN) identity index and a first list of one or more network slices supported by a first PLMN associated with the first PLMN identity index. The second message is associated with one or more neighboring cells, and includes the first PLMN identity index and a second list of one or more network slice data associated the first PLMN as supported by the one or more neighboring cells. In addition, at least one of the one or more network slice data in the second list includes a sub-list of one or more neighboring cell data.

Abstract: Systems and methods for using integrated access and backhaul (IAB) nodes configured to provide multi-access edge computing (MEC) functionality are disclosed herein. An TAB node includes a distributed unit (DU) having a local application instance of a MEC-enabled application. The local application instance is configured for communication with a first user equipment (UE) connected to the TAB node. A mobile termination functionality (MT) of the IAB node uses a packet data convergence protocol (PDCP) layer to transport data of the local application instance between the MT and an IAB donor. Further, data of the local application instance is transported between the UE and the TAB node via one of a variety of methods, including the use of a second PDCP layer at the DU (and optionally the use of service data adaptation protocol (SDAP) layers at each of the DU and the MT), and/or via sidelink.

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).
