D2D multicast communications can reduce communication cost and decrease interference in Internet of Vehicles (IoV). In this paper, the resource allocation algorithm for Device-to-Device (D2D) multicast communication reusing LTE network uplink resource is studied to improve the reliability of networks. The optimization objective of the algorithm is to minimize the outage probability of D2D multicast group links on the basis of guaranteeing the constraint of cellular link quality. To solve this optimization problem, a low-complexity heuristic algorithm is designed for spectrum resource allocation and power control. By comparing performance through simulation, it can be found that the outage probability of the heuristic algorithm designed in this paper can be very close to that of the Hungarian algorithm, but the computational complexity is greatly reduced compared with the latter.
