Joint Backhaul and Access Link Resource Management in Maritime Communication Network

The increasing maritime activities with the exclusive economic zone lead to increasing demands for wideband communications in recent years. This paper presents a maritime communication network architecture where the onshore high-tower base station provides wireless backhaul for the shipborne base stations, while the shipborne base stations serve as the mobile access points for the user ships. Under this architecture, considering the out-of-band full-duplex (OBFD) backhauling mode, we propose a joint backhaul and access link resource management scheme in respect to the wireless backhaul power allocation, access link power allocation and user association, for the sake of maximizing the network capacity. Specially, this scheme takes the inter-cell interference and the multiuser association into account in order to model the realistic maritime communication scenarios. The optimization problem is solved by the successive convex approximation (SCA) method and the numerical simulation results show the effectiveness of the algorithm in terms of the network capacity and the iteration convergence.
