Embodiment 1

[0027] figure 1 It is the main flowchart of Embodiment 1 of the present invention, such as figure 1 As shown, Embodiment 1 mainly includes:

[0028] Step 101, pre-divide the time slot resources used by two adjacent three cells into three parts, wherein, all available frequency resources of the system on a part of the time slot resources will be used as dedicated time-frequency resources, and the system frequency resources on a part of the time slot resources All available frequency resources will be used as common time-frequency resources, and all available frequency resources of the system on a part of time slot resources will be used as shared time-frequency resources shared by the three cells; according to the divided time slot resources, determine the Dedicated time-frequency resources and common time-frequency resources.

[0029] What needs to be explained here is that in the existing network model, the number of cells that can be adjacent to each other is three. Theref...

Abstract

The invention discloses a method for coordinating interference, comprising the following steps: dividing time slot resources of adjacent three cells into three parts in advance, wherein all system available frequency resources on one part of time slot resources serve as special time frequency resources, all system available frequency resources on another part of the time slot resources serve as common time frequency resources, and all system available frequency resources on the rest part of the time slot resources serve as shared time frequency resources for the three cells; determining the special time frequency and the common time frequency resource for each cell according to the divided time slot resources; and distributing resources for cell edge users (CEU) and cell central users which request for dispatching respectively by using the above divided time frequency resources so as to lead the system to carry out flexible resource configuration according to the current position of the dispatched users, thus realizing interference coordination among cells which are suitable for a TDD mode system.

Description

technical field [0001] The invention relates to an interference coordination technology in a mobile communication system, in particular to a method capable of realizing interference coordination in a time division duplex (TDD) mode. Background technique [0002] In a mobile communication system, due to the different fading speed experienced by users at different locations, the signal-to-noise ratio C / I is very different, resulting in a large difference in throughput or data rate between users at the edge of the cell and users at the center of the cell. , which not only affects the capacity of the entire system, but also makes the quality of service obtained by users in different locations very different. How to improve the performance of cell edge users is one of the main issues to be considered in the next generation mobile communication system. [0003] In the time division multiplexing-orthogonal frequency division multiple access (TDM-OFDMA) system, due to the use of or...
