Vehicular SUDAS for 5G high mobility V2X scenarios

In this paper, we present a Vehicular version of the Shared UE-side Distributed Antenna System (SUDAS) i.e. Vehicular SUDAS which enables high throughput wireless communication in high mobility Vehicle-to-X (V2X) scenarios. Vehicular SUDAS uses shared virtual antennas, termed UE-side Radio Units (URUs), which utilize both licensed sub-6 GHz band and unlicensed millimetre wave band, to achieve a virtual MIMO gain in in-vehicle UEs. A simulation study is performed to evaluate and analyze an upper bound of the maximum achievable sum rate in the downlink of the proposed system, assuming perfect Doppler spread compensation. The proposed Vehicular SUDAS shows excellent performance, positioning itself as a strong contender for next V2X communication services.
