Frequency self-configuration method, device and system

Abstract

The embodiment of the invention discloses a method, a device and a system for self-configuration of frequency, which aim at solving the problem that the existing frequency self-configuration technology cannot configure the working frequency for a plurality of common-carrier wave receiving and sending devices in the common-cell scheme. The method comprises the following steps of enabling a base station to obtain the air interface interference value of each frequency of each receiving and sending device which is connected with the base station in the preset frequency list, dividing the receiving and sending devices carrying the same carrier wave into one collection, defining the weighted sum value of the air interface interference values of the frequencies of the receiving and sending devices in the collection as the comprehensive interference value of the frequency in the collection, and configuring the frequency with minimum comprehensive interference value in the collection to each receiving and sending device in the collection to be used as the working frequency for carrying the carrier wave corresponding to the collection. The method has the advantages that the configured frequency has the minimum comprehensive interference value at each common-carrier wave receiving and sending device, the minimum interference of the working frequency of the base station is effectively ensured, and the integral coverage quality is improved.

Description

Technical field [0001] The invention relates to a wireless communication system, and in particular to a frequency self-configuration method, device and system. Background technique [0002] With the development of indoor coverage solutions, wireless access solutions have derived a co-cell solution, which has become an indoor coverage solution with obvious advantages due to its advantages such as easy access to households, easy management of neighboring cell relationships, and ease of achieving accurate coverage. [0003] figure 1 Shows a schematic diagram of the system structure of the co-cell solution. The base station is connected to the transceiver 0, the transceiver 1 and the transceiver 2 for communication. The transceiver can include a radio remote unit or a baseband remote unit, etc. The transceivers can carry the same load For example, transceiver 0, transceiver 1 and transceiver 2 all carry carrier C0, transceiver 1 and transceiver 2 both carry carrier C1, transceiver 3 al...
