Embodiment Construction

[0050] The following embodiments are described by taking the micro base station as an HeNB as an example.

[0051] In the embodiment of the present invention, through the exchange of subframe attribute information through the network, the HeNB can realize effective interference control, and the MeNB can realize effective interference avoidance; further, the subframe configuration information of the micro base station and the macro base station can be notified to the HUE and the MUE respectively through the air interface. Station subframe configuration information enables HUE and MUE to perform effective measurement and wireless link monitoring. Specifically:

[0052] The HeNB obtains the preset subframe attribute information, the subframe attribute information includes at least the muting subframe set and / or the protected subframe set; then, the HeNB generates the corresponding micro base station subframe configuration based on the obtained subframe attribute information info...

Abstract

The invention relates to the field of communication and discloses a method, a device and a system for realizing interference control and interference avoidance, and the method, device and system disclosed by the invention can be used for effectively lowering the strong interference on an MUE (MeNB user) in a coverage range caused by a micro base station in a network with different hierarchies. The method comprises: the micro base station and the MeNB obtain same subframe attribute information used for representing the setting modes of a muting subframe and / or protected subframe; the micro base station can effectively dispatch HUEs (Home NodeB users) within a scope of jurisdiction according to the obtained subframe attribute information, and controls the downlink transmission of the HUEs to realize interference control; and the MeNB can effectively dispatch MUE within a scope of jurisdiction according to the obtained subframe attribute information, indicates the MUE to measure and report parameters on the proper measurement position and controls the downlink transmission of the MUE so as to realize interference avoidance, therefore, strong interference on the MUE caused by the micro base station can be effectively avoided, and the throughput of the layered networking is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for realizing interference control and interference avoidance. Background technique [0002] With the increasing requirements of data rate and business load, the traditional way of providing access by single-layer coverage of macro base stations can no longer meet the needs of use. Therefore, currently, access is usually provided by layered coverage, that is, in hot spots Some low-power micro base stations (such as HeNB, Pico, Femto, Relay, etc.) are deployed indoors to cooperate with macro base stations to complete access. The so-called micro base station is a kind of base station equipment applied in the home indoor environment, office environment, or other hotspot small coverage environment, which can provide higher data rate and lower cost services. [0003] For the convenience of expression, the following abbreviations or abbreviations are defin...
