With the development of the communication technology, more and more new technologies emerge, in order to meet the needs of users and cope with
The challenge of other technologies, wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system
Use the networking mode of heterogeneous network (Heterogeneous Network, Hetnet).Heterogeneous network is i.e. by macro base station
The small micro-base station (Pico base station) of covering is added in the coverage area of (Macro base station) and carrys out networking.
Hetnet, which has the advantage that, increases cell throughout, and its cost is than the homogeneous network of full macro base station networking
(Homogeneous Network, Homonet) wants low.
In heterogeneous network, the transmission power of macro base station is bigger than the transmission power of micro-base station, and which results in isomery
The uplink equalization point and downlink equalization point of user equipment (User Equipment, UE) in network are misaligned.Uplink equalization point
It is defined as：When some position between macro base station and micro-base station UE, macro base station and micro-base station receive on this position
Ascending power from the UE is identical.Downlink equalization point is defined as：When some position between macro base station and micro-base station UE,
What UE was received on this position is identical with the descending power of micro-base station from macro base station.
It was found by the inventors of the present invention that since uplink and downlink equalization point is misaligned, when UE brings uplink interference to micro-base station,
The downlink signaling of micro-base station can not correctly be understood by UE, and micro-base station is caused to be unable to control the transmission power of UE, so as to cause micro-
Base station can not inhibit interference of the UE to it.
