Interference control method and device for same frequency network of macro and micro base stations

Abstract

The invention is suitable for a communication field, and provides an interference control method and device for a same frequency network of macro and micro base stations. The method comprises that: the micro base station scans wireless environment in which the micro base station is, to obtain a scanning result; the micro base station reports the scanning result to a superior network unit, so as that the superior network unit can determine the a residential area with strongest micro base station signal intensity based on the scanning result, and configures configuration parameters of the residential area to the micro base station; the micro base station respectively judges whether each service channel is carried out service loading by the micro base station; for the service channer of which service is not loaded by the micro base station, the micro base station obtains an upward interference estimator of UE to the micro base station on the service channel, and offsets the upward interference estimator in the upward signal on the received service channel. The method and the device provided by the invention, based on a network structure of same-frequency arranging the macro base station and one or more micro base station which are stacked in a covering range of the macro base station, reduces upward interference caused by UE, and raises network throughput.

Description

technical field [0001] The invention belongs to the field of communications, and in particular relates to an interference control method and device for co-frequency networking of macro and micro base stations. Background technique [0002] In recent years, the mobile Internet has developed vigorously, the network coverage of operators has been continuously extended, and it has become possible to surf the Internet anytime and anywhere; Cause cell congestion and affect network performance. In order to increase network capacity, micro cells (Micro cells) can be superimposed within the coverage of macro cells (Macro cells). [0003] In the case of co-frequency networking between the micro base station and the macro base station, there is a soft handover area within the coverage of the two. If the user equipment (User Equipment, UE) in the soft handover area works in the macro cell, since it is in the At the edge of the cell, the transmission power is large, which will cause up...

[0003] In the case of co-frequency networking between the micro base station and the macro base station, there is a soft handover area within the coverage of the two. If the user equipment (User Equipment, UE) in the soft handover area works in the macro cell, since it is in the At the edge of the cell, the transmission power is large, which will cause uplink interference to the micro base station, thereby increasing the bottom noise of the micro base station and reducing the capacity of the micro base station
