Abstract: Leveraging perception from radar data can assist multiple communication tasks, especially in highly-mobile and large-scale MIMO systems. One particular challenge, however, is how to distinguish the communication user (object) from the other mobile objects in the sensing scene. This paper formulates this user identification problem and develops two solutions, a baseline model-based solution that maps the angle of the object from the radar scene to communication beams and a scalable deep learning solution that is agnostic to the number of candidate objects. Using the DeepSense 6G dataset, which has real-world measurements, the developed deep learning approach achieves more than 89% communication user identification accuracy on the test set, highlighting a promising path for enabling integrated radar-communication applications in the real world.
