APPARATUS AND METHOD FOR MANAGING MULTI-CARRIER

摘要

PURPOSE: A device and a method for managing a multiple subcarrier are provided to minimize a wireless resource by dynamically reducing a main subcarrier in consideration of each subcarrier channel property. CONSTITUTION: A channel information receiver(120) receives channel quality information of each subcarrier of a multiple subcarrier from a terminal. A main subcarrier determining unit(140) selects one subcarrier among the multiple subcarrier according to reference information including the channel quality information of each subcarrier. A change request unit(150) gives an instruction to change the main subcarrier with one subcarrier selected by the current subcarrier.
