Interference control method and network equipment thereof

Abstract

The invention discloses an interference control method and network equipment thereof, relates to the technical field of wireless communication field, and can relieve the problem that the data transmission performance of terminal equipment is reduced in a wireless network because of the interference control of a power control technology. The method comprises the following steps: determining an equivalent correlation coefficient between the signal of first terminal equipment and interference noise by utilizing channel estimation result, wherein the channel estimation result is the channel estimation result of an upstream channel used by the first terminal equipment; determining the relationship between the equivalent correlation coefficient and a preset threshold, if the equivalent correlation coefficient is more than the maximum value of the preset threshold, allocating assigned frequency resource to the first terminal equipment, wherein the assigned frequency resource which is allocated to the first terminal equipment is different from the frequency resource used by second terminal equipment. The invention also discloses network equipment for applying the interference control method.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an interference control method and network equipment. Background technique [0002] In an existing wireless communication network, interference often exists between different cells, thereby reducing the communication quality of terminal devices in the wireless communication network. Therefore, power control technology is often used in this field to alleviate the interference between small cells. For example, all terminal devices in a cell can use all frequency resources, but the power of a terminal device in a cell on a frequency band It is different from the power of terminal equipment in other cells on the same frequency band. For example: cell 1 is adjacent to cell 2, terminal device 1 is in cell 1, the power of terminal device 1 on frequency band 1 is A, and terminal device 2 is in the cell 2. The power of the terminal device 2 on the frequency band 1 ...

Problems solved by technology

[0003] However, in practical applications, in order to reduce the interference to adjacent cells, the transmit power of the terminal equipment in this cell is often reduced. However, the reduction of the transmit power of the terminal equipment will lead to a decrease in the data transmission performance of the terminal equipment in the wireless network.
