Sensing and Communication Integrated System for Autonomous Driving Vehicles

Facing fatal collisions due to the sensor's failure, the raw sensor information sharing among autonomous driving vehicles is critical important to guarantee the driving safety with the enhanced see-through ability. This paper proposes a novel sensing and communication integrated system based on the 5G New Radio frame structure using the millimeter wave (mmWave) communication technology to guarantee the low-latency and high data rate information sharing among vehicles. And the smart weighted grid searching based fast beam alignment and beam tracking algorithms are proposed and evaluated by the developed hardware testbed. Field test results prove that our proposed algorithms can achieve a stable data rate of 2.8 Gbps within 500 ms latency in a mobile vehicle communication scenario.
