Abstract

The invention provides a method and a device for expanding an RRU cascade cell. The method includes the following steps: acquiring the basic information of an RRU cascade cell; determining whether the RRU cascade cell needs expansion according to the basic information; if determining that the RRU cascade cell needs expansion according to the basic information, calculating a background noise theoretical value and a background noise compensation value, and acquiring a background noise factory configuration value; acquiring the maximum value among the background noise theoretical value, the background noise compensation value and the background noise factory configuration value, and taking the maximum value as the optimal configuration value of background noise; and configuring the background noise of the RRU cascade cell according to the optimal configuration value of background noise. The potential of RRU cascade cells can be fulfilled to the maximum. Finally, RRU cell expansion is realized. The user rate and user number of RRU cascade cells are improved. The expansion cost of RRU cells is reduced greatly. The expansion cycle is reduced. The efficiency of expansion is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for expanding the capacity of an RRU cascaded cell. Background technique [0002] The WCDMA system is a self-interference system, and the cell capacity is closely related to the system interference level, and the Received Total Wide Band Power (RTWP) is often used to measure the interference level of the base station. When the base station is unloaded, RTWP is equal to the noise floor of the base station. Abnormal reasons such as traffic increase, RRU cascading, external interference, antenna feeder radio frequency failure or any system loopholes, abnormal terminals, etc. may lead to an increase in RTWP. RTWP increases due to different reasons should be dealt with differently. [0003] Cascading RRUs will cause the RTWP to increase even when the base station is unloaded, resulting in a decrease in system capacity and rat...
