Embodiment Construction

[0052] Embodiments of the present invention relate to a method and device for adjusting antenna coverage, which are used to solve the existing problem of low accuracy of antenna coverage adjustment.

[0053] At present, cell coverage for users is mainly achieved by adjusting the azimuth, downtilt, and lobe width. The azimuth represents the characteristics of the horizontal coverage of the cell, the downtilt represents the vertical coverage, and the lobe width represents the coverage. The lobe width is mainly realized by configuring different amplitudes and phases. For a certain cell, the more accurately the azimuth, downtilt angle, and lobe width are identified, the more accurate the coverage will be and the better the coverage effect will be. it is good.

[0054] In the embodiment of the present invention, the user will be accurately positioned according to the reported information of the user in the specific implementation, and then after fully considering the impact of the ...

Abstract

The invention discloses a method and a device for adjusting antenna coverage, which are used for solving the problem of low accuracy during antenna coverage adjustment in the prior art. According to the embodiment of the invention, when antenna coverage adjustment is carried out; according to the number of the terminals in the cell, the sampling position of at least one terminal in the cell and the sampling frequency at the sampling position, and determining the lobe width and the azimuth angle of the cell, determining the downward inclination angle of the cell according to the position and the height of the base station to which the cell belongs, the position and the height of the base station to which the adjacent cell belongs and the determined lobe width, and adjusting the antenna corresponding to the cell according to the determined azimuth angle, the downward inclination angle and the lobe width. Therefore, when the antenna coverage is adjusted, the lobe width, the azimuth angleand the downward inclination angle of the cell are directly and accurately calculated, so that the antenna of the cell can be directly adjusted according to the accurately determined azimuth angle, downward inclination angle and lobe width, and the cell coverage accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for adjusting antenna coverage. Background technique [0002] With the development of LTE (Long Term Evolution, Long Term Evolution), the number of LTE users has increased dramatically, and how to meet the precise coverage of users has become a difficult problem. [0003] At present, cell coverage for users is mainly achieved by adjusting the azimuth, downtilt, and lobe width. The azimuth represents the characteristics of the horizontal coverage of the cell, the downtilt represents the vertical coverage, and the lobe width represents the coverage. The lobe width is mainly realized by configuring different amplitudes and phases. For a certain cell, the more accurately the azimuth, downtilt angle, and lobe width are identified, the more accurate the coverage will be and the better the coverage effect will be. it is good. [0004] When ad...
