Provided is a method of transmitting data from a digital unit (DU) to one terminal via remote radio heads (RRH). The method comprises: a first round trip delay measuring step of measuring first round trip delay values between the DU, which is to transmit data, and each of the RRHs; a second round trip delay step of measuring second round trip delay values between a user terminal, which is to receive the data, and each of the RRHs; and a data transmission step of transmitting the data from the DU via the RRHs using the first and second round trip delay values. According to the present invention, it is possible not to increase complexity in a terminal when one DU transmits data to a terminal via multiple RRHs and to maintain synchronization between a base station and the terminal and between the base station and the RRHs. |
