Three-dimensional multiple access method for joint radar and communication enabled V2X network

A novel multiple access method in domain of time, spectrum and space is analyzed in this paper for radar communication integration enabled vehicular network. With co-designing of radar and communication signal, a novel spacial division method using radar signal modulation and demodulation can be realized using Butler beam-forming method. Division for resources of time slots and spectrum is redesigned with the implement of novel spacial division method. To avoid signal collision a specified reservation mechanism is proposed to support the QoS requirement for latency and throughput, as well as a novel spacial division method to ensure precision signal alignment.
