Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for de-registration of the wireless device from a first access type over a second access type. Methods also include procedures for maintaining state machines associated with both access types as well as procedures to determine a connection for re-transmitting a de-registration request and to avoid collisions between procedures associated with the first and second access types. Further, methods include an information element configured to indicate which access type has been de-registered.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a C-V2X capable wireless device configured to operate according to a first sidelink mode where communication resources are allocated by a network and a second sidelink mode where communication resources are autonomously allocated by the wireless device. The wireless device detects a change in a coverage scenario associated with the first sidelink mode; performs resource sensing for the second sidelink mode; and based at least in part on detecting the change in the coverage scenario, transmits first communications using the second sidelink mode, wherein resources for transmitting the first communications are allocated based at least in part on the resource sensing.

Abstract: Techniques disclosed herein relate to reducing RRC signalling messages. Techniques can be employed to reduce the number of Random Access Channel (RACH) attempts to obtain NotBroadcasted (e.g., On Demand System Information(s) (SIs)) by a UE in response to a paging message indicating SI modification. The UE may monitor the Physical Broadcast Channel (PBCH) for a given duration in attempt to decode the On Demand SI(s) without initiating a RACH procedure. If the UE fails to decode the On Demand SI(s) within the given duration, the UE may initiate a RACH procedure to obtain the On Demand SI(s).

Abstract: Techniques are disclosed relating to handover of WLAN voice calls to one or more cellular networks. In some embodiments, a device is configured to perform voice communications over one or more wireless local area networks, communicate with a first network using a first cellular radio access technology (RAT), and communicate with a second network using a second cellular RAT. The device may store, based on communications via the first network, information indicating that the first network does not support voice communications for the apparatus. The device may handover a voice call from a wireless local network directly to the second cellular RAT, based on the stored information and without handover of the voice call to the first cellular RAT, based on call conditions on the wireless local area network.

Abstract: Emergency services support is indicated to roaming devices in a wireless network. A user equipment (UE) may receive a message from the wireless network indicating at least one public land mobile network (PLMN) that provides emergency services support for devices in limited service. The UE may store, in a non-volatile memory (NVM), an identifier of the at least one PLMN in a whitelist of limited service emergency services support. In response to a trigger in a roaming limited service condition of the UE, the UE may establish an emergency session with a selected PLMN based on the whitelist of limited service emergency services support.

Abstract: Systems, devices and methods for a user equipment (UE) to perform public land mobile network (PLMN) selection with a non-terrestrial network (NTN) dedicated to an international area. The UE receives a downlink message from the NTN, where the downlink message includes a public land mobile network (PLMN) identifier of a first PLMN of the NTN including an information element (IE). The IE indicates that the NTN is dedicated to an international area. Responsive to receiving the downlink message, the UE determines a current location of the UE and determines whether the current location is in the international area. The UE provides an international area notification to an access and mobility management function (AMF) servicing the UE to forward to a home PLMN (HPLMN) of the UE indicating whether the current location is in the international area.

Abstract: This disclosure relates to techniques for a wireless device to determine a radio access technology availability indicator to present. A wireless device may establish a wireless link with a cellular network via a cell that operates according to a first radio access technology. The wireless device may determine if access to the cellular network is also available via a cell that operates according to a second radio access technology, by configuration by the serving cell or from another standalone cell. The wireless device may select a radio access technology availability indicator to present based at least in part on determining if access to the cellular network is also available via a cell that operates according to the second radio access technology.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for enhancement of multi-SIM devices, such as UE 106. A network may increase paging retries for known MU-SIM devices, e.g., based on an indication of capabilities from a MU-SIM device. The indication may be via a NAS registration request, an RRC capability procedure, and/or an RRC UE assistance procedure. Additionally, a network may include an indication of a paging priority to the UE. The UE may then determine a response to the page based, at least in part, on the indicated priority. Further, the UE may indicate a tune-away to the network. The indication of the tune-away may include a cause and/or duration for the tune-away and may be provided at an RRC level or a network access stratum (NAS) level.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to avoid invalidation of a subscriber identity module (SIM). A UE may initiate a connection with the network. The network may reject the connection attempt. The UE may selectively determine whether to invalidate the SIM, network, or both. The UE may consider various factors such as details of the connection rejection message, identity of the network, its relationship to the network (e.g., whether the network is a preferred network, etc.), a number of connection rejections received, time remaining on one or more timers, availability of other networks, etc.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE), manufacturer server, and/or cellular network to perform radio capability signaling. A new type of UE radio capability identifier is provided which may allow a network to distinguish between similar UEs that have or have not implemented a capability update. In order to perform a forced capability update, a manufacturer may issue information about the update to a cellular network (and receive acknowledgement of the information) prior to pushing the update to UEs. In response to an unforced capability update, a cellular network may maintain multiple UE radio capability identifiers for similar UEs which have or have not implemented the update. A UE radio capability identifier may be adjusted dynamically in response to temporary changes in the UE's capability.
