Roadside unit Message Transmission Management

Various embodiments include method performed by a processor of a roadside unit (RSU) processing system for controlling a message transmissions. In various embodiments, the RSU processing system may receive vehicle-to-everything (V2X) information from a vehicle, determine, based on the received V2X information, a minimum reception distance at which the vehicle or operator of the vehicle will reliably receive a message from the RSU and have time for the vehicle to react to the message, determine a transmission power level based on the determined minimum reception distance, and transmit the message to the vehicle using the determined transmission power level. In various embodiments, the RSU processing system may determine the transmission power level taking into account vehicle speeds, vehicle locations, road conditions, weather conditions and/or the type of message being transmitted.
