Abstract

The method comprises receiving a detection signal sent by a UE in a first area, and determining whether the UE is an interfering UE based on the detection signal; if yes, sending a power control signal to the interfering UE. By means of the present invention, a micro base station can determine an interfering UE and reduce transmit power of the interfering UE by sending a power control signal to the interfering UE, thereby reducing interferences by the interfering UE on the micro base station.

Description

 TECHNICAL FIELD The present invention relates to communication technologies, and in particular, to an interference control method, apparatus, and system. Background technique

 In a macro-cellular network, the quality of users in the edge area and the user service area in the macro-cell hotspot area are often not guaranteed.

 The prior art improves the quality of service of users in these areas by setting up a micro cell in the edge area of the macro cell and the hot spot area, that is, using a heterogeneous network (Heternet network). However, since the transmit power of the microcell base station is inconsistent with the transmit power of the macrocell, the uplink power balance line is different from the downlink power balance line. FIG. 1 is a schematic diagram of the uplink and downlink power balance lines in the prior art, as shown in FIG. The uplink power balance line 1 has the same distance from the macro cell base station and the micro cell base station respectively, and the downlink power balance line 2 is close to the micro cell base station. The so-called uplink power balance line means that the UE is on the uplink power balance line 1 with the same power to the macro. The cellular base station and the micro cell base station transmit signals, and the macro cell base station and the micro cell base station receive the same signal power. The so-called downlink balance line means that the macro cell base station and the micro cell base station send signals to the UE with different powers, and the UE is in downlink power. When the line 2 is balanced, the received signal power is the same, and the soft handoff area refers to the area between the soft handoff boundary line 3 and the soft handoff boundary line 4. Both the macro cell base station and the micro cell base station can control the UE in the soft handoff area. .

 The serving cell of the user is divided by the downlink power balance line. Therefore, when the user is in the area between the uplink power balance line i and the soft handover boundary line 3 in FIG. 1, the serving cell of the UE is a macro cell base station, but is in this area. The uplink transmission signal of the UE causes a large interference to the micro cell base station.
