Abstract

The embodiment of the invention discloses a method for reducing base station interference. The method comprises: receiving first interference information which comprises related information of the intensity of interference from MNB (marco node B) and the request bandwidth of small-scale cellular nodes; acquiring the degree of the interference of MNB downlink signals in the small-scale cellular nodes according to the first interference information; and adjusting the system operation parameters of the MNB according to the interference degree. The embodiment of the invention changes the adjustment for the transmitting power of the small-scale cellular nodes in the prior art into the adjustment for the system operation parameters of the MNB, wherein the system operation parameters comprise bandwidth or / and the transmitting power. As the small-scale cellular nodes are not adjusted, the coverage of the small-scale cellular nodes cannot be increased; the MNB downlink performance in a region cannot be affected; the coverage of the MNB in the region cannot be reduced; furthermore, the total throughput of the MNB and the small-scale cellular nodes can be increased, and the use efficiency ofspectrum is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for reducing base station interference. Background technique [0002] In a communication network, there are many base stations and cells formed by mobile nodes under the coverage of the base stations. Among them, the design goal of the macro-cell base station (Macro NodeB, MNB) is to meet the mobility requirements of users' outdoor business applications, while the home base station (Home NodeB, HNB) or femto-cell (femto-cell) are both for home or office The small cell access node covered by the regional network mainly provides high-quality and convenient indoor high-speed wireless access for the home or office area, so that users can enjoy higher-quality broadband data services. Because small cell access nodes such as HNB or femto-cell are more economical and efficient than MNB in ​​solving the problems of indoor small-scale effective c...
