Random Beam-Based Random Access for Low-Latency Device-to-Device Communication Systems
IEEE Access, 2020 In this paper, we consider a device-to-device communication system, where a multi-antenna mobile user directly communicates with nearby multiple devices, and propose a low-latency random access protocol utilizing random beams at the user.
