TY  - JOUR
AB  - In this paper, we consider a dense vehicular communication network where eachvehicle broadcasts its safety information to its neighborhood in eachtransmission period. Such applications require low latency and highreliability, and thus, we propose a non-orthogonal multiple access scheme toreduce the latency and to improve the packet reception probability. In theproposed scheme, the BS performs the semi-persistent scheduling to optimize thetime scheduling and allocate frequency resources in a non-orthogonal mannerwhile the vehicles autonomously perform distributed power control. We formulatethe centralized scheduling and resource allocation problem as equivalent to amulti-dimensional stable roommate matching problem, in which the users andtime/frequency resources are considered as disjoint sets of players to bematched with each other. We then develop a novel rotation matching algorithm,which converges to a q-exchange stable matching after a limited number ofiterations. Simulation results show that the proposed scheme outperforms thetraditional orthogonal multiple access scheme in terms of the latency andreliability.
