Centralization and Collaboration in 5G Ultra-dense Network Architecture

摘要

An ultra-dense network scenario is a scene which a large numbers of people assemble in limited areas to generate centralized broadband data traffic requirements. Ultra-dense networks generate enormous traffic pressure, and traditional network capabilities are far from enough to accommodate the user's needs. Based on the description of ultra-dense network structure, this paper analyzes millimeter wave radio spectrum, high gain beam forming, physical layer frame structure, resource concentration and Mobile Edge Calculation techniques. The cooperative technologies required by overlay and interference symbiosis in the dense network architecture, as well as the access control technology of centralized access, are analyzed and discussed comprehensively.
