Patent application number | Description | Published |
20130010658 | Method and system for implementing synchronization among micro base stations - The present disclosure provides a method and system for implementing synchronization among micro-base stations, including: a micro-base station intercepts a wireless reference signal of an air interface, and selects a synchronization reference object according to an intercepted wireless reference signal; and the micro-base station implements synchronization processing through detecting the wireless reference signal of the selected synchronization reference object, and adjusts its own synchronization information. The method for implementing synchronization among micro-base stations disclosed in the present disclosure is implemented on the basis of the wireless air interface signals of the micro-base stations, requires no additional synchronization hardware devices (such as Global Positioning Satellite (GPS) receiving apparatus, etc.) and has low cost. By the solution disclosed in the present disclosure, the mutual interference caused by asynchronization between a Time Division Duplex (TDD) micro-base station and other base stations is eliminated flexibly. | 01-10-2013 |
