METHOD OF TRANSMITTING DATA FOR REDUCING INTERFERENCE IN HIERARCHICAL CELL STRUCTURE

摘要

PURPOSE: A data communications method for reducing the interference in a hierarchical cell structure of enhancing the transmission efficiency of data is provided to reduce the interference of the femto base station by changing the carrier wave of the terminal. CONSTITUTION: If there is interference from a femto base station, a macro MS(Mobile Station) performs a channel scan(S125). The terminal transmits the channel measurement report(S140). A macro BS varies a PC(Primary Carrier) of A terminal into mark into label(S150). The base station transfers the carrier wave change to label to label to the terminal(S155). The terminal alleviates the interference of the femto base station to label to the base station and label through the changed carrier wave(S160).
