Embodiment Construction

[0057] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0058] Schematic such as figure 1 shown. The circular repelling area is taken as an example for analysis, but the present invention is not limited to a circle, and may be a square, sector, triangle or other irregular shapes.

[0059] The specific implementation of the base station includes the following steps:

[0060] Step 1: Information Gathering and Modeling

[0061] Step 1.1: Information Gathering

[0062] The ground base station obtains user location information through user reports to estimate the user density λ c . Signaling interaction is performed between the base station and the drone, and the base station obtains information such as the location of the drone to estimate the density of the drone λ u , the transmission power configuration μ of the UAV u , the main lobe gain G of the UAV antenna array m , side lobe gain G s , ...

Abstract

The invention discloses an unmanned aerial vehicle deployment method in an unmanned aerial vehicle assisted cellular network, and belongs to the technical field of wireless communication. The method comprises the steps of: enabling a base station to collect information according to different information sources, and establishing a probabilistic sight distance transmission model according to the collected information; secondly, selecting unmanned aerial vehicle deployment scheme parameters and user classification; thirdly, based on the model and the proposed unmanned aerial vehicle deployment and user access method, selecting a key performance index according to a specific scene and demand; evaluating the selected key performance indexes of the three types of users by adopting an analysis method of a random geometry theory in a given group of parameter settings; after multiple sets of parameter settings are evaluated, searching the size of the optimal repulsion area and the optimal unmanned aerial vehicle height; and finally, implementing an unmanned aerial vehicle deployment scheme. The interference suppression and evaluation method provided by the invention has the advantages of simplicity, quickness and universality, can remarkably reduce signaling overhead and system complexity, is transparent for users, does not need the users to carry out additional measurement and report, and reduces the burden of the users.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a drone deployment method for a drone-assisted cellular network. Background technique [0002] Unmanned Aerial Vehicle (UAV) as an air access point can effectively improve coverage, regional spectral efficiency, and user quality of experience. Therefore, introducing UAV communication into cellular networks is a promising technology that can significantly improve UAV Communication performance with existing ground users. Compared with ground access points, the flexible, rapid and on-demand deployment of drones enables them to provide comprehensive coverage and data transmission services for emergency scenarios with coverage holes, hotspots, remote areas or communication failures without the need to build new ground communication related infrastructure. In addition, another significant advantage of UAVs compared to ground base stations is the higher probability of ser...
