    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: This disclosure provides systems, methods, and apparatus for wireless communications that support fast user equipment (UE) handover between base stations. A UE may receive, from a source base station, a configuration for reference signal transmission at a set of uplink transmit power levels. The UE may transmit multiple uplink reference signal repetitions based on the configuration. The source base station may transmit a request message to a target base station to measure the multiple uplink reference signal repetitions. The target base station may select an uplink reference signal and measure a transmit power correction. The target base station may transmit an indication to the source base station of the selection and transmit power correction. The source base station may evaluate the indications and select the target base station. The source base station may forward to the indicated contents, and the UE may switch and synchronize with the target base station.

    Abstract: Methods, systems, and devices are described for managing data connectivity at a user equipment (UE). The managing may include determining that all traffic of all PDN connections of the UE is currently offloaded to a Wireless Local Area Network (WLAN) access network and then refraining from transmitting and receiving data over Wireless Wide Area Network (WWAN) PDN connections while all traffic of all PDN connections of the UE is offloaded to the WLAN access network. In response to detecting a triggering event, a PDN connection may be established with at least one of an available WWAN access network or the WLAN access network, according to a current WWAN camping status of the UE and a WLAN offload policy.
