Abstract: Scheduling communications using a plurality of wireless interfaces is provided. Signals received from an antenna are monitored to detect a level of congestion over a message protocol. Responsive to the level of congestion exceeding a first threshold, a transmission mode is transitioned to a first mode which allows use of first and second subchannels for sending messages. Responsive to the level of congestion being below a second threshold, the second threshold being indicative of a lower level of congestion caused by message protocol traffic over the plurality of subchannels than the first threshold, the transmission mode is transitioned to a second mode which allows use of the first subchannels but not the second subchannels for sending the messages. One or more subchannels over which to send a first message of the messages are chosen in accordance with the transmission mode. The first message is sent using the antenna.

Abstract: Filtering of V2X messages is performed by an ego vehicle. A velocity of travel of the ego vehicle is identified. One or more distance thresholds of dynamic filter criteria are adjusted according to the identified velocity. Via a transceiver of the ego vehicle, a vehicle-to-everything (V2X) message is received. From the V2X message, a location of a remote road entity of the V2X message is identified. The V2X message is filtered based on whether the location of the remote road entity is within the one or more distance thresholds. The V2X message is only processed if the V2X message is not filtered out, thereby reducing resource usage due to the filtered out V2X messages.

With a scheduler in a selective excluded resource mode, the controller identifies CSR for transmitting the data packet based on the primary subchannels in response to at least one of the size of the data packet being less than a packet size threshold and at least a portion of the primary subchannels being available to transmit the data packet; and identifies the CSR for transmitting the data packet based on the plurality of subchannels in response to at least one of the size of the data packet being greater than or equal to the packet size threshold and the primary subchannels not being available to transmit the data packet.

Abstract: A vehicle broadcasts a lane change intent message indicating parameters of a maneuver to be performed by the vehicle operating as a main traffic participant vehicle, the maneuver requiring use of a road resource. Response messages are received from recipient vehicles indicating approval or disapproval of performance of the maneuver. Responsive to one of the recipient vehicles returning a response message indicating conflict with use of the road resource required for performance of the maneuver, a conflict resolution procedure is performed between the main traffic participant vehicle and the conflicted recipient vehicle, the conflict resolution procedure using a pre-agreed identical conflict resolution algorithm executed on each of the main traffic participant vehicle and the conflicted recipient vehicle to each make a same distributed decision whether to proceed with the maneuver.
