The present disclosure provides a full duplex communication method implemented by a Radio Base Station (RBS) supporting Time Division Duplex (TDD) scheme and the associated RBS. The method comprises configuring a first logic cell and a second logic cell for the RBS by specifying a first downlink/uplink (DL/UL) configuration corresponding to the first logic cell and a second, different DL/UL configuration corresponding to the second logic cell. The method also comprises transmitting a first wireless signal to a first UE associated with one of the first and the second logic cells and receiving a second wireless signal from a second UE associated with the other of the first and the second logic cells simultaneously in a subframe, which is allocated for DL communication according to one of the first and the second DL/UL configurations corresponding to the one of the first and the second logic cells and is allocated for UL communication according to the other of the first and the second DL/UL configurations corresponding to the other of the first and the second logic cells. Self-interference suppression is performed to suppress interference from the transmission of the first wireless signal to the reception of the second wireless signal.
