Abstract: Techniques are disclosed relating to apportioning data between network links in dual-connectivity environments. In some embodiments, a packet data convergence protocol (PDCP) entity implemented by a mobile device determines a ratio for sending packet data to two or more different radio link control (RLC) entities implemented by the mobile device for dual connectivity communications via two or more different networks. In some embodiments, in response to a current data volume meeting a threshold value, the PDCP entity apportions packet data between the two or more different RLC entities based on the determined ratio. The ratio may be determined based on various input parameters from one or more protocol layers or may be specified by the network. In various embodiments, the disclosed techniques may improve resource utilization and reduce re-ordering delay at the receiver.

Abstract: An accessory device may establish a short range link to a companion device, and the accessory device may use the companion device as a proxy to conduct a data session over a cellular network. Based on a latency requirement associated with the data session and/or a signal strength of the short range link, the accessory device may dynamically determine to transition its cellular radio from a powered-off mode to a low power mode.

Abstract: This disclosure relates to providing coexistence features for cellular communication in unlicensed spectrum. A wireless device may communicate with a cellular base station in accordance with an original communication configuration. The wireless device may determine that a communication activity is occurring at the wireless device that has a duration longer than a duration threshold. The wireless device may provide an indication to the cellular base station to modify the communication configuration with respect to operation in an unlicensed frequency band based at least in part on determining that a communication activity is occurring at the wireless device that has a duration longer than the duration threshold. The wireless device may communicate with the cellular base station in accordance with a modified communication configuration.

Abstract: A device, system, and method uses a camp only mode based on a connectivity status. The method is performed at a device that is configured to establish a first connection to a first network and configured to establish a second connection to a second network. The method includes determining the connectivity status of the device. When the connectivity status indicates that the device has established the first connection, the method includes utilizing a camp-only mode to monitor the second network, the camp-only mode reducing a frequency of at least one type of operation associated with the second network, the camp-only mode configured to retain a capability of determining whether an emergency message is being broadcast over the second network.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for network assisted side-link resource configuration for unicast and/or multi-cast/groupcast communications in V2X networks. A UE may, after establishing an RRC connection with a base station, transmit, to the base station, V2X connection information. The V2X connection information may include a V2X identifier associated with the UE and a V2X identifier associated with a target UE. The UE may receive, from the base station, a side-link configuration for data transmission with the target UE. The side-link configuration may include a resource allocation defined in time and frequency (e.g., a transmit/receive pool). The UE may communicate with the target UE using the resource allocation included in the side-link configuration.

Abstract: Apparatuses, systems, and methods for non-small data transmission (non-SDT) dedicated radio bearer (DRB) handling while in a radio resource control (RRC) inactive state. A wireless device may determine, while operating in the RRC inactive state, that non-SDT data is available for transmission on a non-SDT DRB and determine, based on one or more conditions, to transmit, to a base station, non-SDT data arrival information during an SDT procedure. The one or more conditions may be associated with arrival time of the non-SDT data and/or an amount of non-SDT data to be transmitted. The arrival time may be relative to arrival of SDT data, initiation of an SDT procedure, and/or initiation of a subsequent transmission period of an SDT procedure.

Abstract: A method and apparatus of a device that communicates data between a user equipment (UE) device and a base station when the user equipment is in the inactive state is described. In some embodiments, the last serving base station of the UE and the new base station of the UE coordinate with each other to complete the transfer of data while the UE is in the inactive state.
