摘要：
An apparatus for allocating subchannels is provided. The apparatus includes: a subchannel allocation coefficient determination unit determining a subchannel allocation coefficient using a queue length of at least one terminal and a signal to interference plus noise ratio (SINR) of the at least one terminal and at least one relay station in an Orthogonal Frequency Division Multiple Access (OFDMA) system; and a subchannel allocation unit allocating a subchannel to at least one link formed in the OFDMA system using the subchannel allocation coefficient.
