Abstract

The invention provides a three-dimensional cell splitting method and a three-dimensional cell splitting device. The three-dimensional cell splitting method comprises the following steps: calculating the horizontal-dimension and vertical-dimension angles of arrival of each terminal; calculating the horizontal-dimension half-power beam width according to a preset horizontal-dimension cell splitting number; calculating a horizontal-dimension main lobe pointing angle set according to the distribution of the horizontal-dimension angles of arrival of the terminals; calculating a vertical-dimension cell splitting number according to the maximum and minimum vertical-dimension angles of arrival; calculating the vertical-dimension half-power beam width according to the maximum vertical-dimension angle of arrival, the minimum vertical-dimension angle of arrival and the vertical-dimension cell splitting number; calculating a vertical-dimension main lobe pointing angle set according to the vertical-dimension cell splitting number and the vertical-dimension half-power beam width; and carrying out cell splitting according to the horizontal-dimension half-power beam width, the vertical-dimension half-power beam width, the horizontal-dimension main lobe pointing angle set and the vertical-dimension main lobe pointing angle set. By further splitting a cell in the vertical dimension, the capacity of the system is improved greatly.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular to a three-dimensional cell splitting method and device. Background technique [0002] In the early stage of mobile cellular communication network construction and deployment, each cell has the same size and capacity, but as the number of users increases, the user density is no longer equal. In order to adapt to this situation, in areas with high user density, it is necessary to use cell splitting technology to increase the number of available channels, thereby increasing the capacity of the system. [0003] The sector division technology is one of the cell splitting technologies, specifically, one omnidirectional antenna of the base station is replaced with multiple directional antennas in the horizontal dimension. Each directional antenna radiates a designated sector, increasing frequency reuse frequency, thereby increasing system capacity. Usually...
