Embodiment Construction

[0032] figure 1 It is a schematic diagram of an interference coordination method according to an embodiment of the present invention. This example includes:

[0033] Step 105, obtaining interference indication information including interference load

[0034] Step 110, the first access node reports interference indication information including the interference load to the first base station through an air interface, and requests the first base station to perform interference coordination.

[0035] The executor of this embodiment is the first access node. The above-mentioned first access node includes a relay RelayNodeB, a home base station HeNB, a micro base station Pico NodeB, an indoor base station Femto Cell, or a remote radio head Remote Radio Head; the above-mentioned first base station includes a macro base station, a home The base station HeNB, the pico base station Pico NodeB other than the first access node, or the indoor base station Femto Cell other than the first...

Abstract

The invention discloses a coordination method of interference, equipment and a system thereof. The method comprises the following steps: the interference indication information of an interference load is obtained; a first access node reports the interference indication information of the interference load to a first base station through an air interface and requests the first base station to carry out interference coordination, or the first base station carries out interference coordination according to interference indication information which comprises the interference load and sends wireless resource coordination information to the first access node through the air interface wherein the first access node comprises Relay NodeB, HeNB, PicoNodeB, Femto Cell or Remote Radio Head. According to the invention, the communication flow of the interference coordination process is simplified, the time delay of the process is reduced, the communication resource in the process of usage is reduced, and the user experience of the process is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to an interference coordination method, device and system. Background technique [0002] In order to improve the flexibility of the wireless communication system, in the prior art, base stations with different transmission powers or different access types can be deployed within the same geographical coverage area, for example, a macro base station and a low-power base station are deployed together. It is also possible to deploy two low-power base stations in adjacent areas. The aforementioned low-power base stations include a relay NodeB, a home base station HeNB, a micro base station Pico NodeB, an indoor base station Femto Cell, or a remote radio head Remote Radio Head. [0003] In this mixed deployment scenario, in order to further improve the spectrum utilization efficiency of the system, the low-power base station and the macro base station, or the user equi...
