Embodiment Construction

[0043] As mentioned in the background technology section, how to improve the security of the physical layer in the three-dimensional heterogeneous network is an urgent problem to be solved by those skilled in the art.

[0044] The core idea of ​​the present invention is to use analysis tools such as random geometry and random matrix to analyze the physical layer security connection probability of the cellular heterogeneous network micro base station users configured with full-dimensional antennas, and according to the security connection probability, it is possible to find the The ratio of the distribution density between the micro base station and the macro base station with the highest probability of secure connection of the micro base station user, so as to find the distribution density of the micro base station.

[0045] see figure 1 , an embodiment of the present invention provides a full-dimensional antenna heterogeneous network micro base station deployment method, the ...

Abstract

The invention discloses a micro base station deployment method based on physical layer security performance for configuring a full-dimensional antenna heterogeneous network. For the first time, this method considers the influencing factors of the physical layer security performance index under the beamforming method of the vertical dimension of the full-dimensional antenna; and according to the influencing factors, the secure connection probability of the user of the micro base station is derived, and finally the deployment density of the micro base station is obtained.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a method for deploying a micro base station in a heterogeneous network of full-dimensional antennas. Background technique [0002] As a key technology of the fifth-generation mobile communication, large-scale antennas can effectively improve spectrum utilization; at the same time, heterogeneous networks can improve the coverage of the system and the throughput of the entire network. Therefore, both the macro base station and the micro base station in the heterogeneous network are equipped with large-scale antennas to improve the transmission rate of the system. In the deployment of large-scale antennas, due to size constraints, rectangular antenna arrays are generally used, which are called full-dimensional antenna arrays; in addition to adjusting the horizontal dimension, the full-dimensional antenna array can also adjust the vertical dimension angle, thereby elim...
