Embodiment Construction

[0044] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments.

[0045] A wireless communication network includes multiple base stations, and each base station has its own service area, which is also called a cell. Generally speaking, there are intersecting areas between cells of adjacent base stations, and when a mobile user is located in or near these intersecting areas, it is easily affected by wireless signals sent by two or more base stations. The present invention constructs CoMP cell clusters for users in the wireless communication network before the base station performs CoMP operations.

[0046] As we all know, a complete wireless communication network includes many base stations, refer to figure 1 , the present invention first selects L adjacent cells among them to form an area where CoMP cell cluster construction is to be performed. The size of L can be flexibly configured according to actual requiremen...

Abstract

The invention provides a structuring method of a CoMP cell cluster, which comprises the steps of: selecting an area to be carried out the structuring of the CoMP cell cluster from a wireless communication network, and preliminarily determining mobile users needing the CoMP operation in the area; sequentially finding out same users adopting same communication resources, similar users adopting partial same communication resources and different users adopting completely different communication resources from the preliminarily determined mobile users needing the CoMP operation; and structuring the CoMP cell cluster for the same users, the similar users and the different users according to the priority level from high to low. The CoMP operation performed by the structuring method of the CoMP cell cluster not only improves the performance of edge users, but also simultaneously considers the overall performance of the system.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular to a method for constructing a CoMP cell cluster. Background technique [0002] In recent years, with the rapid development of mobile communication technology, various new services emerge in an endless stream. At the same time, the user's performance requirements for mobile communication systems are also increasing. One of the goals of the IMT-Advanced system currently proposed by the ITU-R is to improve the performance of cell edge users. In a single-cell scenario, the edge users are far away from the base station, and the path loss is relatively serious. In theory, at this time, the method of increasing the transmit power of the base station can be used to meet the effective SINR requirements of the edge users, thereby improving the call quality of the edge users . However, in real scenarios, multiple cells often coexist, and users at the edge of the cell ...
