Problems solved by technology

In fact, during the moving process of HAP, the distribution of users in its coverage area will change. In some areas, users are more concentrated, and in some areas, users are more scattered. Using fixed beams cannot maximize the use of system capacity.

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] Please refer to figure 1 , the present invention provides a method for adaptive coverage optimization of a mobile high-altitude communication platform based on perception, comprising the following steps:

[0041] Step S1: The mobile base station collects the reference signal sent by the ground user, and obtains the coordinates of the ground user;

[0042] Step S2: The mobile base station obtains the current position according to the self-contained positioning device, and calculates the user density according to the collected user coordinates;

[0043] Step S3: According to the user density, compare the typical value of the scene type in the database to determine the scene type;

[0044] Step S4: Obtain the information data of the adjacent mobile base station;

[0045] Step S5: Adjust the dynamic beam according to the obtained scene type and t...

Abstract

The invention relates to a mobile high-altitude communication platform adaptive coverage optimization method based on perception, and the method comprises the following steps of S1, enabling a mobilebase station to collect a reference signal sent by a ground user, and obtaining a ground user coordinate; S2, enabling the mobile base station to obtain the current position according to a built-in positioning device, and calculate the user density according to the collected user coordinates; S3, comparing the typical values of the scene types in a database according to the user density, and determining the scene types; S4, acquiring the information data of an adjacent mobile base station; and S5, adjusting the dynamic beam according to the obtained scene type and the information data of the adjacent mobile base station. According to the invention, the wave beam is adaptively selected through a plurality of types of perception information, so that the adaptive coverage is realized, and theredundant coverage or coverage holes of the mobile HAP caused by the ground scene change and the user distribution change can be better improved.

Description

technical field [0001] The invention relates to a perception-based adaptive coverage optimization method for a mobile high-altitude communication platform. Background technique [0002] HAP (High Altitude Platform, high-altitude communication platform) is a system that provides communication services for the ground by a communication platform floating at an altitude of 20km~50km. It is composed of a space segment and a ground segment. An array antenna, which communicates with the gateway station to send and receive independent planar antennas and transceivers with regenerative capabilities; the ground segment is composed of gateway stations and user terminals, each terminal is managed by one of the gateway stations, and each gateway station is both a control center , is also the switching center. [0003] HAP combines the technical advantages of terrestrial wireless systems and satellite systems, and can achieve large-area and high-density coverage with a small amount of ne...
