Problems solved by technology

This method alleviates the edge effect of the collaboration area to a certain extent, but essentially still requires the interaction between different collaboration areas, there is still coupling between the collaboration areas, and the complexity of scheduling still exists

[0036] Figure 4 It shows a schematic diagram of the division of the initial cooperation area according to the first embodiment of the present invention. Seven initial cooperation areas of the entire wireless network are determined according to the scope of the cooperation area and the positions of the base stations of each cell in the wireless network, and the seven initial cooperation areas are respectively Different line types are used for identification. Taking the initial cooperation area in the center as an example, the initial cooperation area is composed of cells 1-19, and cells 1-7 are not adjacent to other initial cooperation areas, so cells 1-7 form the In the internal area of ​​the initial cooperative area, the cells 8-19 are respectively adjacent to other cooperative areas, so the cells 8-19 constitute the external area of ​​the initial cooperative area.

[0041] Image 6 It shows a schematic diagram of the division of initial cooperation areas according to the second embodiment of the present invention. Seven initial cooperation areas are determined according to the scope of the cooperation area and the base stations of each cell in the wireless network, and the seven initial cooperation areas are respectively separated by different lines. In the wireless network of this embodiment, three cells share one base station. Taking the initial cooperation area in the center as an example, the initial cooperation area is composed of cells 1-21, and cells 1-21 are formed by seven base stations. Management control, where cells 1, 2, 3, 8, 13, 21 are not adjacent to other initial cooperation areas, so cells 1, 2, 3, 8, 13, 21 constitute the internal area of ​​the initial cooperation area, cells 4, Cells 5, 6, 7, 9, 10, 11, 12, 14, 15, 16, 17, 18, 19, and 20 are respectively adjacent to other cooperation areas, so cells 4, 5, 6, 7, 9, 10, ...

Abstract

The invention relates to a wireless network and discloses a method and an apparatus for dividing cooperation areas in a wireless network. The method comprising: acquiring the orientation of antennas in various districts in the wireless network, the positions of base stations in the various districts, and a range of the cooperation areas; determining initial cooperation areas according the range of the cooperation areas and the positions of the base stations in the various districts; dividing the initial cooperation areas into an internal area and an external area; dividing the external area into an inward area and an outward area according to the orientation of antennas in the various districts in the external area and the positions of the base stations in the various districts in the external area; and combining the internal area with the inward area in the external area to be a new cooperation area. The method is easy to execute and resolves a problem of cooperation area edge caused by cooperation area division. In addition, the method prevents association between cooperation areas so as to reduce scheduling complexity.

Description

technical field [0001] The present invention relates to a wireless network, in particular to a method and a device for dividing cooperation areas in the wireless network. Background technique [0002] As people's demand for wireless network data services continues to increase, how to improve system throughput and spectrum efficiency as much as possible has become the focus of next-generation wireless networks. The cooperation between base stations is an important technology to fully obtain the potential capacity of the system. Through the interaction between cells, the local information of each cell can be fully utilized, and network resources can be coordinated and scheduled to obtain better global performance. The first step of cooperation is to determine the area of ​​cooperation and determine the base station and cell of cooperation. [0003] Generally speaking, there are three methods to determine the coordinated cell: the network decision method, the user decision me...
