Abstract: Disclosed are embodiments for authentication and authorization in a 5G network between an edge enabler client (EEC) of a UE and an edge configuration server (ECS). The embodiment include performing primary authentication with the 5G network to obtain a KAUSF; generating a Kedge and a Kedge ID using the KAUSF and a subscription permanent identifier (SUPI); providing the Kedge and the Kedge ID to the EEC to cause it to compute a MACEEC using the Kedge and an EEC ID; and sending to the ECS an application registration request, the application registration request including the EEC ID, MACEEC, and Kedge ID.

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: This disclosure relates to techniques for supporting switching between point to point and point to multipoint delivery with service continuity for broadcast and multicast services in a wireless communication system. A cellular base station and a wireless device may establish a wireless link. The cellular base station may provide information configuring an over the air delivery type with which to receive a broadcast or multicast service, which may be received by the wireless device. The cellular base station may transmit the service using the configured delivery type, and the wireless device may correspondingly receive the service. The cellular base station may provide information configuring the wireless device to switch to a different over the air delivery type, with service continuity. The cellular base station may then transmit the service using that delivery type, and the wireless device may correspondingly receive the service.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform a method for supporting a periodical radio access network (RAN) notification area (RNA) mechanism when small data transmission (SDT) is enabled for a user equipment device (UE). The method may include the UE receiving, from a base station, an indication enabling an SDT procedure along with an indication of an RNA timer configuration, transitioning, to a radio resource control (RRC) inactive state, and initiating an RNA timer based on the RNA timer configuration. The UE may, upon initiation of the SDT procedure, stop the RNA timer and, upon termination of the SDT procedure, start the RNA timer. During the SDT procedure, the UE may receive any of an SDT termination indication, an SDT subsequent transmission indication, or an SDT subsequent transmission termination indication that may include an updated RNA timer configuration (and/or RNA timer reconfiguration).

Abstract: Methods, systems, apparatuses, and computer programs for enhancing UE handover. In one aspect, the method can include obtaining a request for a handover event from a UE, wherein the request includes at least (i) a request for access to a primary cell group and (ii) data indicating capabilities of the UE, determining, based on the UE capabilities, that the UE is capable of maintaining communication with a secondary cell group of a base station during handover of the UE to the primary cell group of the first base station, generating based on the determined UE capability, a handover command that instructs the UE to maintain communication with the secondary cell group of the base station during handover of the UE to the primary cell group, encoding the generated handover command for transmission to the UE, and transmitting the generated handover command to the UE.

Abstract: A UE may perform a location-based conditional handover (CHO) based on a region information and size parameter associated with a serving cell of a non-terrestrial network (NTN). In time-based CHO, the UE may perform CHO in response to expiration of a network-configured wait time. Alternatively, the UE may perform CHO by randomly selecting a wait time from a network configured time range. The selection may be randomized using a network provided seed or using a cell Radio Network Temporary Identifier (RNTI) value. In elevation-based CHO, the UE may perform CHO in response to the elevation angle of a satellite being less than a network configured threshold. When the UE is configured with multiple cells of the NTN, and the CHO criteria for two or more of the cells are satisfied, the UE may select a target cell for CHO based on network indicated prioritization of the cells.

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 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: H04W76/27
Abstract: While in an inactive state, a user equipment (UE) device transmits a message to a base station. The message indicates the UE device's intent to perform transmission and/or reception of user data with the network during the inactive state. The message may include a portion of the user data and/or a buffer status report. The UE device receives a response message that induces a state transition in the UE device. Different state transitions (e.g., to idle, inactive, legacy inactive, connected) may be induced by different types of response message (e.g., release, release with suspend configuration, resume, setup). One particular type of response message causes the UE to stay in the inactive state and enables subsequent user data transmission/reception in the inactive state. The response message may implicitly (or explicitly) indicate that forwarding of the user data to a core network was successful.

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A base station may receive from user equipment device (UE) a random access initiation message, having a characteristic that is configured to indicate to the base station a requested size of a subsequent uplink grant to be provided by the base station for transmission of uplink data by the UE. For example, the characteristic may include a predetermined preamble included in the random access initiation message, such that a requested grant size is indicated by which preamble the UE selects from a plurality of possible preambles. As another example, the characteristic may include which RACH occasion is selected by the UE to transmit the random access initiation message. In response, the base station may allocate resources for use by the UE based on the characteristic.
