Abstract

In the C-V2X environment, the high-speed movement of vehicles makes it impossible to obtain full CSI, and vehicles multiplexing of cellular resources causes interference to original network. This paper attempted to maximize the sum ergodic rate of system while ensuring reliability for V2I link and V2V link under partial CSI. It proposed the joint power control and channel multiplexing resource allocation algorithm. Firstly, according to the reliability constraint, it used geometric programming to analyze the feasible regions of power, and obtained the optimal power control for any single multiplexed pair. Then, the algorithm transformed channel multiplexing into a maximum weight bipartite graph matching problem by using the ergodic rate of the multiplexed pair as the weight of the bipartite graph and solved it by the KM algorithm. The simulation results show that, compared with other algorithms, the proposed resource allocation algorithm can optimize the resource allocation, effectively control the interference, and improve the sum ergodic rate of system while ensuring reliable communication for vehicles.
