Problems solved by technology

[0004] However, not all antennas of the interference source network equipment are polarization-adjustable antennas. In order to suppress the interference signal of the interference source network equipment, it is necessary to replace the antenna of the interference source network equipment with a polarization-adjustable antenna, and the cost of replacing the antenna is high.

Embodiment Construction

[0049] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0050] Under normal circumstances, the uplink signal sent by the terminal device to the target network device will inevitably be interfered by the interference signal sent by the interference source network device, causing the uplink signal to be submerged in the interference signal of the interference source network device, resulting in the loss of the uplink signal , causing c...

Abstract

The present invention provides an antenna adjustment method and device, by obtaining the antenna height difference and distance between the first antenna of the target network device and the second antenna of the interference source network device, and the first zero beam of the vertical plane of the first antenna Width, according to the distance, antenna height difference and the width of the first null beam, determine the target electronic downtilt angle of the first antenna, and then adjust the current electronic downtilt angle of the first antenna to the target downtilt angle according to the target downtilt angle, so that the first The upper null point of the antenna faces the second antenna, that is, the upper null point of the first antenna faces the interference source network device. In this process, when the downtilt angle of the first antenna is the target downtilt angle, the induced voltage of the antenna is the smallest. Therefore, the upper zero point of the first antenna faces the interference source network device, and the interference signal of the first antenna is the weakest from the second antenna.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna adjustment method and device. Background technique [0002] With the continuous development of communication technologies, more and more network devices are deployed in the same area, and terminal devices can choose to connect to different network devices for communication. [0003] Usually, the signal sent by the terminal device to the network device is called an uplink signal, and the signal sent by the network device to the terminal device is called a downlink signal. The signal quality of the uplink signal and the downlink signal is one of the important factors affecting the quality of communication services . During the uplink signal sending process, the terminal device sends an uplink signal to the target network device. For the target network device, other network devices are interference source network devices, and the signal sent by the interference ...
