Abstract： An ultra-dense network scenario is a scene where a large number of people assemble in a limited area to generate centralized broadband data traffic requirements. Because ultra-dense networks generate enormous traffic pressure, traditional network capabilities are not enough to accommodate the user’s needs. Based on the description of ultra-dense network architecture, we analyze millimeter wave radio spectrum, high gain beam forming, physical layer frame structure, resource concentration and edge computing technology. In addition, the cooperative technology required by overlay and interference symbiosis in the dense network architecture as well as the access control technology of centralized access is analyzed and discussed comprehensively.
Key words： ultra-dense network architecture; millimeter wave; edge computing; multi-point collaboration

摘 要：超密集网络场景指大量的人聚集在有限的区域形成集中的宽带数据业务需求的场景。 超密集网络会产生巨大的流量压力， 传统的网络能力远远不足以承载用户的需求。 本文在阐述超密集网络组网架构的基础上， 对毫米波无线频谱、 高增益的波束赋型、 物理层帧结构以及资源集中与边缘计算技术进行了分析， 并对在密集组网架构中必然产生的覆盖与干扰共生所要求的协作技术以及集中接入的接入控制技术进行了综合的分析探讨。
