面向舰船编队的5G无人机基站群组网接入方案研究

Research on the access scheme of 5G UAV base station group oriented to ship formation

基于通航运行事故突发性、复杂性、动态性、信息缺失性等的特点,无人机技术与我国通航事故应急救援体系有机结合,成为当前海上应急通信研究热点。用户为中心的无人机基站群组网打破传统以基站为中心的架构,为每个用户选取潜在服务站点集合,构建动态的基站组,使得用户可以充分利用基站组内潜在服务站点的多样化增益,以及潜在服务站点间的协作增益。提出了以用户为中心的无人机基站群组网方案,并针对适合船舶编队场景的用户初始接入方案进行设计和性能仿真评估。

Based on the characteristics of suddenness, complexity, dynamics and lack of information of navigation accidents, UAV technology has been organically integrated with China ′ s navigation accident emergency rescue system, becoming a research hotspot of maritime emergency communication.The user-centered UAV base station group network breaks the traditional base-centered architecture, and selects the set of potential service sites for each user to build a dynamic base station group, so that users can make full use of the diversified gain of potential service sites within the base station group and the cooperation gain between potential service sites.In this paper, a user-centered base station group networking scheme for UAV is proposed, and the user initial access scheme suitable for ship formation scenario is designed and its performance is simulated and evaluated.
