UAV-carried small base station communication system and method

Abstract

The invention discloses a UAV-carried small base station communication system. The UAV-carried small base station communication system comprises a plurality of UAV-carried small base station clusters,high power nodes and cloud computing centers, wherein each UAV-carried small base station cluster is formed by a plurality of UAV-carried small base stations in a self-organizing way, and provides access, edge processing and edge caching services for users under the coverage together; the UAV-carried small base station clusters take the high-power nodes based on cloud computing as gateways; the high-power nodes based on cloud computing provide wide-area coverage functions, and are connected with the cloud computing centers; and the cloud computing centers realize centralized network control and management functions. The application also provides a UAV-carried small base station communication method. Through application of the UAV-carried small base station communication system and method,time delay can be reduced effectively; the user experience is improved; the two-dimensional coverage of a traditional communication network is extended to three-dimensional coverage; interference isreduced effectively; and dense coverage is realized. Moreover, the system and the method are compatible with an existing network. and have the advantages of relatively low deployment cost and flexiblenetworking.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a small base station communication system and method carried by an unmanned aerial vehicle. Background technique [0002] Compared with 4G, the coverage capacity of 5G will increase by 1000 times, the peak rate will reach 10Gbps, support 1ms end-to-end delay and one trillion device connections, while maintaining high reliability. Heterogeneous networks and wireless access networks based on cloud / fog computing are two key supporting technologies in 5G access networks. [0003] The heterogeneous-cloud radio access network combines the advantages of heterogeneous networks and cloud computing networks to provide a common network architecture. The heterogeneous-cloud radio access network provides two-layer heterogeneous coverage by deploying high-power nodes and remote radio heads, and the control plane and data plane are decoupled. Among them, the high-po...
