Method, device and system for adjusting uplink power of micro base station

Abstract

The invention relates to the field of communications and discloses a method, device and system for adjusting an uplink power of a micro base station. The method comprises the following steps: when a macro base station causes interference on an uplink signal of the micro base station, an operational maintenance server or the micro base station acquires an uplink control power capable of resisting interference through calculation on the basis of an uplink interlayer power balance principle and in the term of an uplink target power of the macro base station, and adjusts the local uplink power of the micro base station according to the uplink control power. Therefore, when the macro base station causes the interference on the uplink signal of the micro base station, the uplink power of the micro base station can be properly adjusted, therefore, the strong interference caused by the macro base station is effectively overcome, and the signal quality of the macro base station is kept. The invention simultaneously discloses the operational maintenance server, the micro base station and a corresponding communication system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for adjusting the power of a micro base station. Background technique [0002] Traditional mobile communication systems usually use macro base stations (Macro) to achieve single-layer signal coverage. With the increasing requirements of data rate and business load, the traditional single-layer signal coverage method can no longer meet the needs of use. Therefore, layered signal coverage is usually used. Signal coverage method to solve it. The so-called layered signal coverage method is to deploy some low-power micro base stations (Home / Pico / Femto / Relay) in hot spots or indoors on the basis of using macro base stations to achieve single-layer signal coverage. A micro base station is a base station device applied in a home indoor environment, an office environment, or other hotspot small coverage environments, which can provide higher data rates and re...

Problems solved by technology

[0025] From the above calculation results, it can be seen that the interference power of the MUE to the cell covered by the micro base station is higher than the uplink target power of the micro base station, and the difference is 22dB. In this way, it is difficult to guarantee the quality of the uplink signal of UE2 in the cell covered by the micro base station, thus affecting the Normal operation of UE2
