Abstract (en)

[origin: WO2020139854A2] Systems, methods, and devices protect tolling systems from spurious emissions from vehicle-to-everything (V2X) communications. A V2X device may, for example, determine whether a maximum number of vehicles are to transmit using a wireless medium at a particular time. If less than the maximum number of vehicles are to transmit using the wireless medium at the particular time, the V2X device starts transmitting using the wireless medium at the particular time. If, however, the maximum number of vehicles are to transmit using the wireless medium at the particular time, the V2X device delays transmission until less than the maximum number of vehicles are transmitting.
