An apparatus for an uplink (UL) and downlink (DL) subframe configuration in a radio access network considering UL/DL throughputs is disclosed. The apparatus includes a storage unit configured to store information on UL and DL data, and a processor configured to obtain UL throughput and DL throughput based on the information, to calculate a UL and DL subframe allocation ratio indicative of numbers of UL and DL subframes to be allocated to a time division duplex (TDD) window based on the UL throughput and DL throughput, and to determine UL and DL subframe configuration based on the UL and DL subframe allocation ratio.
