METHOD AND APPARATUS FOR CONTROLLING ADAPTIVE FLOW IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method and an apparatus for controlling an adaptive flow in a wireless communication system. A method of a master base station in a wireless communication system, in which base stations having different cell sizes coexist, comprises the steps of: receiving load information from at least one other base station; receiving channel information about the at least one other base station from a terminal connected to the master base station; determining a secondary base station capable of load sharing for the terminal on the basis of the channel information and the load information; and requesting, from the terminal, a further connection to the secondary base station. A base station in a macro cell determines offloading for downlink transmission of the terminal on the basis of the load information of a small cell, and determines a resource distribution ratio of the macro cell and the small cell for downlink transmission of the terminal on the basis of the channel quality information that is reported from the terminal whereby a transmission rate for the terminal can be increased according to the load of the small cell and the channel state of the terminal, and the cell transmission rate of the system can be improved overall.
