    Abstract: User equipment (UE) connection handling is disclosed in which UE environmental status information is used at a network entity to make informed decisions regarding mobility handling and data offloading. A UE determines its environmental status information based on input from at least one non-RF sensor located in the UE. The UE generates and then transmits a control message comprising the UE environmental status information to a network entity in communication with the UE. The network entity receives the control message and uses the UE environmental status information to manage a connection of the associated UE based at least in part on the UE environmental status information.

    Abstract: A gateway device detects a trigger associated with a device and, in response, identifies an application service associated with the device, obtains a traffic network policy associated with the application service, and obtains a network access token based on the traffic network policy. The network access token facilitates validating and/or mapping a downlink data packet obtained at the gateway device in user-plane traffic that is destined for the device. The network access token is sent to an entity in control-plane signaling. Subsequently, the gateway device obtains a downlink data packet including the network access token. The gateway device verifies the network access token and/or maps the downlink data packet to the device using data obtained from the network access token. The network access token may be removed from the downlink data packet before the downlink data packet is sent to the device according to the mapping.

    Abstract: Wireless communications systems and methods related to communications in a wireless network during handover and/or dual connectivity operations are provided. A user equipment (UE) transmits, to a first base station (BS), a first communication signal based on a first time-division multiplexed (TDM) configuration. The UE transmits, to a second BS different from the first BS, a second communication signal, the second communication signal being multiplexed with the first communication signal based on the first TDM configuration. The UE transmits, to the first BS, a third communication signal based on a second TDM configuration different from the first TDM configuration. The first TDM configuration and the second TDM configuration are associated with a handover from the first BS to the second BS. The UE transmits, to the second BS, a fourth communication signal, the fourth communication signal being multiplexed with the third communication signal based on the second TDM configuration.

    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for monitoring a service availability associated with a service of a wireless communication network. A service availability status may indicate availability of the service. A user equipment (UE) may measure signal quality or signal strength associated with frequencies that are related to services of interest to the UE. The UE may manage a service relationship for the service associated with the service availability status. For example, the UE may transmit a radio resource control (RRC) message, an non-access stratum (NAS) message, or other message to indicate the service availability status to the wireless communication network. Alternatively, or additionally, the UE may provide an indication of the service availability status to an application processor or upper layer of the UE when the service availability status changes.

    Abstract: Techniques and apparatus for supporting flexible radio access network (RAN) node identifiers in a network are provided. In one technique, a cell identity of a cell associated with a base station in a network is determined. An identifier of the base station is determined from the cell identity based on a partitioning of an identifier space used for identifying cells in the network. A message that includes at least one of the identifier of the base station or the cell identity associated with the base station is transmitted. In another technique, a user equipment may determine whether to take one or more actions while transitioning from operating in an inactive mode to operating in a connected mode based on the identifier of the base station.

    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for a service-based cell reselection by a user equipment (UE) in a wireless communication system. The UE may have a service relationship with a particular service. A wireless communication system may provide different types of services via different radio frequencies. The UE may determine which cells to measure for cell reselection to include those that correspond to a service of interest to the UE. In addition to power savings, the UE may experience faster cell reselection for a service. The techniques of this disclosure also may enable a priority-based cell reselection so that the UE can camp on a cell that supports a higher priority service compared to other services supported by the UE.
