Abstract: Methods, systems, and devices are described for wireless communications. A wireless communication system may use access preferences to indicate a preferred access for communicating signaling for a control plane service. In some aspects, an AMF and a UE may establish access preferences for one or more control plane services and communicate signaling for the control plane service based on the established access preferences. In some cases, the UE may transmit modified access preferences for a control plane service to the AMF, and the UE and AMF may communicate signaling for the control plane service based on the modified access preferences. In some aspects, an AMF may also restrict the accesses used by a control plane service. A UE may also request that certain accesses are restricted for use by a control plane service.

Abstract: The disclosure relates in some aspects to establishing connectivity with a network using a first set of credentials and determining whether additional connectivity needs to be established (e.g., using a second set of credentials) to communicate data. The disclosure relates in some aspects to the use of multiple credentials for access and service connectivity. For example, traffic generated by a device may be authorized based on a different set of credentials than the set of credentials used to access the network (e.g., to connect to an LTE network for a PDN connection). In this way, traffic belonging to a specific service or application can be charged and policed based on service specific needs. The disclosure thus relates in some aspects to the use of access credentials and service credentials. These different types of credentials can be used to enable traffic differentiation and policing based on the credentials in use.

Abstract: Various embodiments enable broadcast communications security. Various embodiments enable the authentication of broadcast communications. Various embodiments may enable asymmetric authentication and integrity protection of small size messages, such as one or more signed messages totaling a length of 250 bytes or less. Various embodiments may support cryptographic signing of beacon type messages using certificates. Various embodiments may include generating a beacon type message, cryptographically signing the beacon type message at least in part using a certificate to generate a signed beacon message, and sending the signed beacon type message in one or more broadcast transmissions in conjunction with, or independently of, certificate information used to verify the signed beacon message.

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 handover from a next generation access network to a legacy access network may be performed via a next generation core network and a legacy core network. A handover request received at a next generation core network serving node may include an identifier of a target cell within the legacy access network. The next generation core network serving node may identify a legacy core network serving node to which the handover may be forwarded based on the target cell identifier. Packet data units may then be routed over the legacy access network and the next generation core network by mapping data flows in the next generation core network to packet data connections in the legacy access network.

Abstract: Aspects of the present disclosure relate to a mechanism to enable interworking between fifth generation system (5GS) network slicing and evolved packet core (EPC) connectivity. In an example, techniques are provided for existing packet data unit (PDU) sessions that provide connectivity to a network slice from a set of network slices. Connectivity to the network slice is in response to a user equipment (UE), that uses network slices, moving between a 5G network and a 4G network. The existing PDU sessions are connected to a dedicated EPC core network that supports the same services provided by the network slice.

Abstract: Methods, systems, and devices for wireless communication are described that provide for identification, on a per-PLMN basis of a type of core network associated with each PLMN in a list of networks associated with a base station. A user equipment (UE) may receive the list of networks and, based at least in part on the type(s) of core network accessible via each PLMN and a capability of the UE, initiate a connection establishment with a PLMN and associated core network. In some cases, UEs that are not capable of connections with a first type of core network (e.g., a 5G core network) may be restricted from camping on a cell or PLMN that may provide only connections with the first type of core network (e.g., a 4G core network).

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques at a network provide for efficiently considering parameters of a network slice when determining whether to provide access to the network slice, allow the establishment of a session via the network slice, or grant access to resources for communications via the network slice. Further, the described techniques at a user equipment (UE) provide for efficiently determining when or whether to retry to access a network slice, retry to establish a session via the network slice, or retry to access resources for communicating via the network slice.

Abstract: Aspects described herein relate to managing service data flows and corresponding data radio bearers. An indication of a binding between a service data flow and a data radio bearer with an access point can be received. The data radio bearer for binding to the service data flow can be determined as either an existing data radio bearer that supports one or more quality-of-service (QoS) parameters of the service data flow or a new data radio bearer to support one or more data flows of the service data flow. An existing data radio bearer can be modified or a new data radio bearer can be established based on the determination. Based on the binding, a packet can be transmitted using the data radio bearer based at least in part on classifying the packet as related to the service data flow.

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: Certain aspects of the present disclosure relate to methods and apparatus for handling mobility between areas with heterogeneous network slices in wireless communications systems operating according to new radio (NR) technologies. An exemplary method that may be performed by a UE includes receiving an indication that a network slice is not available, entering a connection management idle (CM-IDLE) state, and initiating a registration procedure with an access and mobility management function (AMF) subsequent to entering the CM-IDLE state.
