1. A full duplex communication method implemented by a Radio Base Station (RBS) supporting Time Division Duplex (TDD) scheme, the method comprising:

  • configuring a first logic cell and a second logic cell for the RBS by specifying a first TDD downlink/uplink (DL/UL) configuration corresponding to the first logic cell and a second, different TDD DL/UL configuration corresponding to the second logic cell, wherein the first logic cell and the second logic cell physically correspond to same coverage area;

    transmitting a first wireless signal to a first User Equipment (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 TDD 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 TDD DL/UL configurations corresponding to the other of the first and the second logic cells, wherein the first wireless signal for the first and the second logic cells are combined and then transmitted by the RBS via a same set of one or more antennas, and the second wireless signal for the first and the second logic cells are received by the RBS via a same set of one or more antennas; and

    performing self-interference suppression to suppress interference from the transmission of the first wireless signal to the reception of the second wireless signal.
