Problems solved by technology

The low-frequency band resources are the golden spectrum of the communication system. Compared with the high-frequency band around 2GHz, there is a coverage gain of about 10dB. However, this part of the spectrum allocated to communication operators is mostly used for 2G / 3G network deployment, and the spectrum utilization rate cannot meet the growing traffic. need

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] An embodiment of the present invention provides a method for interference coordination, which is applied to a heterogeneous communication network. The heterogeneous communication network includes at least an interfered base station and an interfering base station. The interfered base station is generally a base station under the re-cultivation network standard, for example NodeB under UMTS and other standards, and the interfering base station is eNodeB under ...

Abstract

The invention, which relates to the technical field of the communication, discloses an interference coordination method. With the method, the co-frequency interference between inter systems can be effectively reduced. The method comprises: a base station under interference receives an interference measurement report fed back by edge user equipment served by the base station; the base station under interference determines an interference coordination information type based on the interference measurement report; the base station under interference informs an interference base station of the interference coordination information type; and the interference base station adjusts the transmitting power based on the interference coordination information type. According to the embodiment of the invention, the method and system are suitable for the inter-system communication process.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an interference coordination method and system. Background technique [0002] With the growth of the number of users and the outbreak of mobile high-traffic services, mobile communication networks will face increasing capacity pressure. From the perspective of operators, obtaining more spectrum resources and improving spectrum utilization are effective means to solve the above problems. The low-frequency band resources are the golden spectrum of the communication system. Compared with the high-frequency band around 2GHz, there is a coverage gain of about 10dB. However, this part of the spectrum allocated to communication operators is mostly used for 2G / 3G network deployment, and the spectrum utilization rate cannot meet the growing traffic. need. Therefore, many operators at home and abroad have begun to consider the re-cultivation of 2G / 3G spectrum, that is, to ...
