Abstract: Systems and methods are provided for public land mobile network (PLMN) selection for disaster roaming. A user equipment (UE) determines a disaster condition at a first PLMN, where the UE is a subscriber of the first PLMN. The UE determines an availability of a second PLMN for disaster roaming. The UE selects the second PLMN and attempts registration on the second PLMN for disaster roaming. In response to attempting the registration on the second PLMN for disaster roaming, the UE receives a registration reject message including a cause value corresponding to a registration failure for disaster roaming on the second PLMN due to the disaster condition on the first PLMN. The UE waits for a first period of time before again attempting to register for disaster roaming on the second PLMN for the first PLMN with the disaster condition.

Abstract: Apparatuses, systems, and methods for enhancement of MBMS transmission reliability. A UE may receive PDCP PDUs via a PTM link from a network. The UE may determine to provide feedback regarding receipt of the PDCP PDUs, e.g., based, at least in part, on an occurrence of a triggering event. The triggering event may be configured by the network and may include the UE receiving a request for feedback from the network, the UE determining that at least one PDCP PDU is missing, the UE determining that a number of missing PDCP PDUs exceeds a threshold, and/or the UE determining that a PDCP reordering window is changing based on expiration of a PDCP reordering timer. The UE may transmit feedback associated with receipt of the PDCP PDUs. The feedback may include an indication of missing PDCP PDUs, e.g., such as an indication of a sequence number associated with missing PDCP PDUs.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for redirecting a user equipment (UE) to an evolved universal terrestrial radio access (UTRA) absolute radio frequency number (EARFCN) of an evolved universal mobile telecommunications service terrestrial radio access network (EUTRAN) band with a band number greater than sixty four. For example, some embodiments are directed to an electronic device including radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry is configured to generate a channel release message and transmit, using the radio front end circuitry, the channel release message to the UE. The channel release message is configured to redirect the UE to the EARFCN of the EUTRAN band with the band number greater than sixty four.

Abstract: Systems and methods are disclosed herein for using integrated access and backhaul (IAB) nodes configured to provide multi-access edge computing (MEC) functionality. An IAB node may include a MEC functionality that includes an instance of an application configured for MEC. A UE using the application connects to the network through an access link with the IAB node and establishes a PDU session for traffic of the application with a core network (CN). The CN may determine that the traffic corresponds to the application, and that an instance of the application is present on the IAB node. Accordingly, the CN may instruct the IAB donor to instantiate a remote packet data convergence protocol (PDCP) layer and, in some cases, a remote service data application (SDAP) layer that are configured to route the traffic from the UE for the application to the instance of the application on the IAB node.

Abstract: The present application relates to improved methods of application instance registration in a Multi-access Edge Computing (MEC) system, comprising, e.g.: receiving, at a MEC platform device, a registration request for a first application instance; determining, by the MEC platform device, that the first application instance is not presently registered; in response to determining that the first application instance is not presently registered, allocating, by the MEC platform device, a first application instance registration identifier for the first application instance; transmitting, by the MEC platform device, the first application instance registration identifier to the first application instance; and causing, by the MEC platform device, a first application instance registration notification to be sent to a MEC system-level management device. According to some aspects, the MEC platform device may first send a permission request to a MEC system-level management device to request permission to be able to register the first application instance.

Abstract: An approach is described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a second UE and a wireless device and a processor communicatively coupled to the transceiver. The processor is configured receive, from the second UE, an end-to-end (E2E) quality of service (QoS) requirement of an E2E connection between the second UE and the wireless device, wherein the E2E connection includes a first hop between the UE and the second UE and a second hop between the UE and the wireless device. The processor is further configured to obtain a first hop link condition and a second hop link condition; split the E2E QoS requirement into a first hop QoS requirement and a second hop QoS requirement based on the first hop link condition and the second hop link condition; and transmit, using the transceiver, the first hop QoS requirement to the second UE. The wireless device is a third UE or a base station.

Abstract: Apparatuses, systems, and methods for emergency communications (e.g., voice calls and/or SMS messages) for UE's without cellular coverage (e.g., in non-cellular coverage). A UE may establish, while out of range of cellular service, a peer-to-peer communication session with a relay UE using a channel in an unlicensed frequency band. The UE may transmit, using the peer-to-peer communication session, an emergency notification to the relay UE. The emergency notification may include an approximate location of the UE. Further the UE may communicate with a Public Safety Answering Point (PSAP), where the communications may be relayed between the UE and the PSAP by the relay UE. The approximate location of the UE may be based, at least in part, on a location of the relay UE and determining the approximate location of the UE may include performing a ranging procedure with the relay UE.

Abstract: The present application relates to user equipment (UE) aggregation. For instance, a UE aggregation group is defined based on a subscription of multiple UEs with a network. Configuration information identifying the UE aggregation group, its member UEs, the role of each UE (e.g., whether a group leader or, otherwise, a group member), and/or radio access capability signaling (RACS) is stored. Upon a registration of a UE, the UE aggregation group is indicated to the network. The network then enables an aggregated communication capability to the UEs of the UE aggregation group based on the configuration information.
