Problems solved by technology

[0006] It can be seen that in the prior art, in order to avoid strong interference to the micro cell, the macro cell needs not to transmit data on some time domain or frequency domain resources. In other words, some resources of the macro cell are unavailable, which will Affect the performance of the macro cell, especially in the performance of the data channel

Abstract

The invention provides a method for promoting interference coordination of a heterogeneous network. The method comprises the following steps that: an LPN (Low Power Node) acquires the information of spatial position of the LPN is in coverage area of at least one macro cell; and the LPN informs the information of the spatial position of the LPN is in coverage area of at least one macro cell to the at least one macro cell according to identifier of the at least one macro cell. The invention further discloses other methods for promoting the interference coordination of the heterogeneous network, as well as a device for promoting the interference coordination of the heterogeneous network. According to the scheme, a macro base station and the LPN can be forced to use different spatial position information to reduce strong interference between the macro base station and the LPN.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and equipment for promoting heterogeneous network interference coordination. Background technique [0002] Heterogeneous network technology is introduced in LTE-A. The heterogeneous network refers to a heterogeneous system in which low power nodes (LPN, Low Power Node) are deployed in the coverage area of ​​the macro base station to form different node types with the same coverage. Since the geographic distance between the access point and the served user equipment (UE) is reduced, the system throughput and overall network efficiency can be effectively improved. The coverage of the macro base station is split from the original single cell into several micro cells due to the deployment of several LPNs. The same frequency band is reused several times, and the system can obtain huge cell splitting gains. Therefore, there will be a large number of edge...
