Roadside unit Message Transmission Management - A simplified explanation of the abstract

This abstract first appeared for US patent application 17455582 titled 'Roadside unit Message Transmission Management

Simplified Explanation

The patent application describes a method for controlling message transmissions in a roadside unit (RSU) processing system. The system receives vehicle-to-everything (V2X) information from a vehicle and determines the minimum reception distance at which the vehicle will reliably receive a message from the RSU and have time to react. Based on this information, the system determines the transmission power level and sends the message to the vehicle using the determined power level.

  • The RSU processing system receives V2X information from a vehicle.
  • The system determines the minimum reception distance for reliable message reception and reaction time.
  • Based on the determined minimum reception distance, the system calculates the appropriate transmission power level.
  • The system transmits the message to the vehicle using the determined power level.
  • Factors such as vehicle speeds, locations, road conditions, weather conditions, and message type are taken into account when determining the transmission power level.

Potential Applications

  • Intelligent transportation systems
  • Vehicle-to-everything (V2X) communication networks
  • Roadside communication infrastructure

Problems Solved

  • Ensuring reliable message reception by vehicles from roadside units
  • Providing sufficient reaction time for vehicles to respond to messages
  • Optimizing transmission power levels based on various factors

Benefits

  • Improved communication reliability between roadside units and vehicles
  • Enhanced safety and efficiency in transportation systems
  • Better control over message transmission based on specific conditions


Original Abstract Submitted

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.
