Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The present invention provides an interference coordination method in the application scenario of a home base station and a macro base station, within the macro cell coverage of the macro base station Macro eNB, in a heterogeneous network HetNet where the home base station femto is deployed, the macro cell users in the idle state The MUE moves to the edge of the femto cell, and the MUE does not belong to a CSG user, the method includes:

[0029] Setting the primary synchronization signal / secondary synchronization signal / primary broadcast channel pattern PSS / SSS / PBCH pattern in the heterogeneous network;

[0030] If the MUE detects interference from a femto cell, start using the PSS / SSS / PBCH pattern; the method further includes: when the MUE...

Abstract

The invention discloses an interference coordination method under home base station and macro base station application context, comprising the steps of: setting a PSS / SSS / PBCH pattern in the heterogeneous network composed of a home base station and a macro base station; moving the macro cell user MUE under leisure state to the edge of the home base station femto cell, wherein the MUE does not belong to the closed user group CSG user; if the MUE detecting the strong interference of the femto cell that is more than the predetermined bearing value, the MUE starting the beforehand known PSS / SSS / PBCH pattern to receive the PSS / SSS / PBCH signal of the macro cell; the femto cell sending or closing the PSS / SSS / PBCH signal in the sending power that is lower than the normal scope according to the PSS / SSS / PBCH pattern. The technical proposal of the invention can correctly obtain the PSS / SSS / PBCH signal of the macro cell under leisure state by MUE in the home base station and macro base station application context and keeps the MUE successfully in the macro base station.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to an interference coordination method in application scenarios of home base stations and macro base stations. Background technique [0002] In the field of mobile communications, the long-term evolution LTE system generally adopts the same-frequency networking method when deploying the network. In this way, the interference between cells, especially the interference at the edge of the cell, will be more serious. Inter-cell interference coordination, interference randomization and interference cancellation are all important. Measures to solve inter-cell interference. In Release8 / 9 of the LTE standard, the main scenario for inter cell interference coordination (ICIC) is the homogeneous network, such as interference at the edge of two macro cells (Macro cell). In Release 10, since it is allowed to In the coverage area of ​​a high-power macro base station (Macro eNB), a low-p...
