Embodiment Construction

[0026] According to the basic idea of ​​the present invention, when designing and realizing the resource allocation method of the entire wireless cellular network, three adjacent cells in the wireless cellular network are regarded as a group, and any of them can be designed according to the method proposed by the present invention. Then, the same design method is applied to other clusters in the network; or, according to the distribution of users of each cluster in the network and their service distribution, the method proposed by the present invention is used to design the distribution of each cluster respectively. An allocation method, wherein the division of available frequency sets for each cluster can be adjusted according to the user and service distribution and system load in each cluster.

[0027] According to the present invention, a kind of frequency multiplexing method that improves cell edge user performance is provided, and described method comprises steps:

Abstract

The method groups three mutual neighboring cells in a wireless cellular network as a cell-group. It designs a distribution scheme of any cell-group among them, then applies to other cell-group with same method. Another way, according to the state of the subscriber and services distribution and the state of system load of each cell-group, designs respectively frequency complexing scheme for that group. The dividing up available frequency in each group can be adjusted according to the state of the subscriber and services distribution and the state of system load of each group. This method splits the subscribers of each cell into the cell central subscribers and the cell margin subscribers, splits each cell-group into several areas and distributes them available frequency according to certain rule. This method raises effectively frequency utilizablity with the precondition of satisfying subscribers' certain comm. requirement.

Description

technical field [0001] The invention relates to a frequency reuse method for improving the performance of cell edge users in the system. The method relates to the technical field of frequency multiplexing in wireless communication, and is mainly used for improving the performance of cell edge users. The method involves multiple access techniques, such as Frequency Division Multiple Access, Orthogonal Frequency Division Multiple Access or other multiple access techniques. Background technique [0002] In the future, new global communication services will put forward higher requirements on the transmission rate, especially how to improve the performance of cell edge users has become an issue of great concern to the industry, such as the long-term evolution of the 3rd Generation Partnership Project (3GPP, 3GPP2) Plan (LTE) and Air Interface Evolution Plan (AIE) put this in particular as an important requirement. Furthermore, according to the characteristics of the future mobi...
