    Abstract: A first user equipment (UE) is configured to communicate with a base station over a Uu link and communicate with a second UE over a sidelink. The first UE transmits a joint scheduling request and a joint buffer status report (BSR) for an uplink transmission on the Uu link with the base station and a sidelink transmission on the sidelink with the second UE. The joint BSR is associated with a relative latency of the uplink transmission and the sidelink transmission. The first UE receives from the base station, a joint transmission grant scheduling the uplink transmission on a first set of resources and scheduling the sidelink transmission on a second set of resources. The first UE transmits a first transmission on the first set of resources for the uplink transmission and a second transmission on the second set of resources for the sidelink transmission.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a cellular modem may transmit, to an applications processor, an indication to use a non-Third Generation Partnership Project (non-3GPP) interworking function (N3IWF) for non-access stratum (NAS) signaling. Accordingly, the cellular modem may establish a first virtual interface with the applications processor. The cellular modem may further perform an Internet Key Exchange (IKE) procedure with a core network using the first virtual interface and the N3IWF and transmit a key generated during the IKE procedure to the applications processor. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) associated with a first radio access network (RAN) may identify a user equipment (UE) connected to a source base station of the first RAN. The AMF may receive a handover message including a voice call continuity handover trigger message indicating a handover of the UE to a target base station associated with a second RAN. In some examples, the AMF may transmit a bypass handover message to a second network device based a on the received handover message. In some cases, the bypass handover message may include the voice call continuity handover trigger message. In some examples, the second network device is a mobility management entity (MME) associated with an Evolved Universal Terrestrial Radio Access Network (E-UTRAN).

    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a user equipment (UE) to select a data connection based on which applications are active in a foreground process of an application processor. The UE may activate a dedicated data subscription (DDS) based on a list of active applications. In some aspects, the UE may programmatically initiate a DDS switch based on which applications are active. The UE may determine which data connection to activate as the DDS based on the application configuration information and which applications are active. Application configuration information may indicate preferences regarding different data connections to use for each application. The application configuration information may indicate a preferred radio access technology (RAT), a preferred communication network, a preferred subscription, or any combination thereof.

    Abstract: Various embodiments provide methods, vehicle computing devices, storage media, and systems for unicast transmission of cellular vehicle-to-everything (C-V2X) Internet Protocol (IP) packets. Various embodiments may enable upper layers in a stack architecture to realize unicast transmission of C-V2X IP packets. In various embodiments, source port and destination IP address pairings may be associated with destination layer 2 (L2) addresses. In various embodiments, a source port indication and destination IP address indication may be added to a unicast C-V2X IP packet, such as a transmission control protocol (TCP) packet, a user datagram protocol (UDP) packet, etc., and the source port and destination IP address indications may be used by a modem to determine the destination L2 address for the unicast C-V2X IP packet.

    Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a modem of a user equipment (UE) may receive one or more parameters that configure the modem to perform a periodic communication to maintain a first connection of the UE; and perform the periodic communication based at least in part on the one or more parameters, wherein the periodic communication is performed on a second connection different than the first connection. In some aspects, an application processor of a UE may establish a connection with a server for a plurality of applications, the server to be configured to communicate with respective application servers for the plurality of applications; configure a modem of the UE to perform a periodic communication to maintain the connection; and provide a push notification, received via the connection and associated with an application of the plurality of applications, to the application.
