Abstract: An in-band full duplex transceiver is provided. The in-band full duplex transceiver includes a distributor and a Finite Impulse Response (FIR) filter. The distributor may include a receiving output terminal that distributes a transmitting signal and a received signal and that outputs the received signal, and a first output terminal that outputs a first signal, which is a signal corresponding to the transmitting signal. The FIR filter may receive an input of a first signal and remove a self-transmitting interference signal that is included in a signal that is output from the receiving output terminal.

Abstract: A method of synchronization in a distributed wireless communication system and a terminal supporting the same are disclosed. A terminal increases its contention window value if it receives a synchronization signal within a synchronization slot. The terminal decreases its contention window value if it receives no synchronization signal within the synchronization slot. The terminal determines whether to transmit a synchronization signal or not by using the increased or decreased contention window value.

Abstract: A method of and an apparatus therefor searching a cell in a mobile station of a communication system in which a plurality of cells are grouped into a plurality of cell groups, and each cell group includes at least two cells. The method includes detecting a primary synchronization signal and a secondary synchronization signal from a received signal, and identifying a cell based on a combination of the primary synchronization signal and the secondary synchronization signal. The secondary synchronization signal is related to the cell group to which the mobile station belongs and the primary synchronization signal is related to the cell to which the mobile station belongs within the cell group.
