Method for suppressing floor noise uplift under home base station

The invention provides a method for suppressing floor noise uplift under a home base station. The method comprises the following steps: calculating the power of a received signal to obtain single floor noise of a system bandwidth; and calculating the average value of the background noise of the system bandwidth within a period of time, and if the average value of the background noise is greater than a preset system background noise uplift threshold and is determined by the demodulation performance of the system, performing uplink gain adjustment on the DRU below the base station, namely adjusting the UL GAIN of the DRU. According to the method and the device, the influence on the demodulation performance of the system caused by the lifting of the background noise due to the combination of multiple DRUs can be effectively reduced, and the service requirements of the users with low signal-to-noise ratios are met while the requirements of the QOS services of the users with high signal-to-noise ratios are ensured
