Support of quality of service for V2X transmissions

A transmitting device comprising:

• circuitry, which, in operation,
• obtains one or more quality of service configurations provisioned to the transmitting device by a network;
• generates vehicular data in an application layer and forwards the vehicular data together with a priority indication to a transmission layer;
• determines, in the transmission layer, one of the one or more quality of service configurations depending on the priority indication forwarded from the application layer;
• and
• performs autonomous radio resource allocation for transmitting the vehicular data via a sidelink interface based on the determined one quality of service configuration, and
• a transmitter, which is coupled to the circuitry and which, in operation, transmits the vehicular data via the sidelink interface to one or more receiving devices according to the autonomous radio resource allocation,
• wherein, in case different sidelink logical channels are multiplexed in one transport block (TB) to transmit the vehicular data, transmission of the TB via the sidelink interface is performed based on a sidelink logical channel associated with the highest priority indication among the different sidelink logical channels associated with priority indications.
