The invention provides an unmanned aerial vehicle
base station group deployment method based on
time correlation. According to the method, a coverage blind area of a ground
base station serves as a target area covered by an unmanned aerial vehicle
base station group, and the deployment position and the deployment range of the unmanned aerial vehicle base
station group are determined according to environmental parameters (position, size and building average height) of the target area. Because link condition fluctuation is caused by conversion between a
sight distance link and a non-
sight distance link in a three-dimensional space channel and change of shielding conditions of obstacles during transmission of an unmanned aerial vehicle base
station, the
instantaneous rate does not accuratelyrepresent the average rate of a network any more,
time correlation is introduced, and
network performance of large-scale time is obtained. Specifically, the interference
correlation coefficient is used for measuring the
time correlation, the joint coverage rate is used for representing the
network performance of large-scale time, and the
optimal deployment height and the number of unmanned aerialvehicle base stations are determined according to the change relation of the joint coverage rate along with the deployment height of the unmanned aerial vehicle base
station group and the number of the unmanned aerial vehicle base stations in the group.
