Abstract: PURPOSE: A data transmission process and an apparatus thereof in a wireless communication system are provided to efficiently transmit data to a terminal from a base station of the wireless communication system including a virtual transmission port. CONSTITUTION: A digital unit (130) connects virtual transmission ports to multiple sub cells. The digital unit transmits data transmitted from a scheduler (110) to antennas through the virtual transmission ports. The virtual transmission ports mix a control channel and a reference signal for a plurality of the sub cells. The scheduler sets up the transmission mode of a terminal included in the sub cell according to the configuration of the virtual transmission ports connected to the sub cells and the signal strength between the terminal and the sub cell. The data for the terminal is scheduled based on the set transmission mode of the terminal.
