Abstract: A user equipment (UE) may identify a bearer (e.g., a default bearer) and request establishment of a second bearer (e.g., a high priority bearer) for use in streaming downlink data from, for example, an application server. The UE may determine a status of a playout buffer and select the first bearer or the second bearer for use in streaming the downlink data associated with the application based on the status of the playout buffer. For example, the first bearer may be used be used by default, and the second bearer may be selected if the amount of data in the playout buffer does not satisfy (e.g., is below) a threshold. In some cases, each bearer may be associated with a transmission control protocol (TCP) port associated with a TCP connection. In some cases, each bearer may be associated with different Internet protocol (IP) address.

Abstract: Various embodiments include methods that may be performed in a computing device of a vehicle for communicating permanent vehicle identification information in vehicle communications in response to detecting that there is a need to send the vehicle permanent identification information to a concerned party. The computing device may generate a message including the vehicle permanent identification information, and transmit the generated message to a roadside unit for routing to the concerned party. In some embodiments, the permanent vehicle identification information may be included in cellular vehicle-to-everything (C-V2X) protocol messages.
