Abstract
In this paper, we study the performance of non- orthogonal multiple access (NOMA) aided relay-assisted multi- casting vehicular communications. Specifically, we consider different road side units (RSUs) connecting vehicular groups to the base station. Each RSU transmits different information to its associated vehicles. In this scenario, we investigate the combined effects of nodes’ mobility, channel estimation error (CEE), and inter-RSU interference. Assuming Nakagami-m fad- ing environment, we derive precise expressions of the outage probability at both strong user and weak user end. Numerical and simulation results are provided to demonstrate the impact of various system/channel parameters and give useful insights into the system behaivor.
