Abstract: In an aspect, a network may support a number of client devices. In such a network, a client device transmits a request to communicate with a network, establishes a security context, and receives one or more encrypted client device contexts from the network. An encrypted client device context enables reconstruction of a context at the network for communication with the client device, where the context includes network state information associated with the client device. The client device transmits a message (e.g., including an uplink data packet) to the network that includes at least one encrypted client device context. Since the network device can reconstruct the context for the client device based on an encrypted client device context, the network device can reduce an amount of the context maintained at the network device in order to support a greater number of client devices.

Abstract: The present disclosure generally relates to identifying, by a processor of a wireless communications device, a service, determining, by the processor and based at least in part on the service, whether to prioritize a type of connection gateway to utilize in connecting to the service, where the processor determines to prioritize the type of connection gateway, selecting, by the processor, a connection gateway for the service based at least in part on a stored network access preference for the service, where the processor determines not to prioritize the type of connection gateway, selecting, by the processor, the connection gateway for the service regardless of the stored network access preference for the service, and connecting, by the processor, to the service via the connection gateway.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may signal one or more emission limits for one or more different frequency bands, and two or more values for one of the emission limits may be provided. A first subset of user equipments (UEs) may be capable of aerial operations (e.g., unmanned aerial vehicles (UAVs) or drones) and may use a first value of the first emission limit and the second subset of UEs may not capable of aerial operations and may use a second value of the first emission limit. A UE status such as altitude or position, or transmission directivity may also be used to determine if the UE is to apply the first value or the second value for an emission limit of a frequency band.

Abstract: Wireless communications systems and methods related to on-demand ultra-reliable, low-latency communication (URLLC) are provided. In one embodiment, a base station (BS) receives, from a user equipment (UE) in a first cell frequency, a request for a protocol data unit (PDU) session over a network slice. The BS receives, from a core network entity, a resource configuration request for the PDU session over the network slice. The BS transmits, to the core network entity, a resource configuration response indicating a cause for rejecting the resource configuration request. In one embodiment, a UE transmits, in a first cell frequency of a network, a network registration request message requesting a network slice of the network that is not provided by the first cell frequency. The UE receives a network registration response message indicating the network slice is allowed based on a second cell frequency of the network providing the network slice requested.

Abstract: Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation radio access technologies (RATs) in a communication network. In some examples, a connectivity request originated by a user equipment towards a next generation core network may be processed by the next generation core network. The next generation core network may then provide the user equipment an indication of whether the next generation core network supports an inter-RAT handover between the next generation RAT and a legacy RAT.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communications system may support techniques for efficient communication between a user equipment (UE) and different entities (or functions) of a core network. Specifically, the UE may interact with a single entity (or function) of a core network (e.g., an access and mobility management function (AMF)), and messages intended for other entities (or functions) may be routed appropriately by this entity. For example, an AMF may receive a message from a UE intended for another entity (or function) of the core network, and the AMF may transmit (or route) the message to the entity (or function). Similarly, the AMF may receive a message from another entity (or function) of the core network, and the AMF may transmit (or route) the message to the UE.

Abstract: The present disclosure provides the UE with ePDG information that includes a list of networks that provide ePDG in the area where the WLAN access point is located. In an aspect, the list of networks may include a list of PLMN IDs. By receiving the ePDG information containing the list of networks that provide ePDG in the area where the WLAN access point is located, the UE may be prevented from selecting an incorrect ePDG. In aspects of the disclosure, a method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the apparatus associates with an access point of a wireless communication network. In another aspect, the apparatus receives, from the access point, ePDG information comprising a list of networks that provide ePDGs in an area of the access point. In a further aspect, the apparatus selects an ePDG based on the ePDG information.

Abstract: A method, operational at a device, includes receiving at least one packet belonging to a first set of packets of a packet flow marked with an identification value, determining that the at least one packet is marked with the identification value, determining to change a quality of service (QoS) treatment of packets belonging to the first set of packets marked with the identification value that are yet to be received, and sending a request to change the QoS treatment of packets belonging to the first set of packets marked with the identification value that are yet to be received to trigger a different QoS treatment of packets within the packet flow, responsive to determining to change the QoS treatment. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described that supports connectivity to a core network via an access network. A user equipment (UE) may establish connectivity with an access network and perform a discovery procedure to identify and select a packet data gateway that provides connectivity to a core network via a core network node. The UE may perform an authentication procedure with the core network node via the packet data gateway to be authenticated with the core network for establishing connectivity with the packet data gateway. The UE may receive a set of control plane addressing information via the packet data gateway corresponding to a secure tunnel established between the UE and the packet data gateway. The UE may perform an attach procedure via the secure tunnel with the core network node without re-authenticating the UE.

Abstract: Some aspects of the disclosure provide various methods, apparatuses and computer-readable medium configured for wireless communication. A method operable at a user equipment (UE) may include transmitting a connection request message configured to request initial connection with a radio access network (RAN) node. The connection request message may include information configured to indicate a service profile of the UE. A method operable at the RAN node may include receiving the connection request message from the UE. The connection request message may include information configured to indicate the service profile of the UE. A method operable at a serving node may include receiving a connection request message from the RAN node. The connection request message may be configured to establish communication with the UE and may include a service profile corresponding to the UE.
