摘要： An apparatus and method for performing Uplink (UL) communication by a Relay Station (RS) in a wireless communication system are provided. The RS receives a Transmit/receive Transition Gap (TTG) and a Receive/transmit Transition Gap (RTG) of a Base Station (BS) during a network entry process of the RS, receives, from the BS, an idle time R_IdleTime between frames used in the RS, and determines a structure of a UL frame. In the alternative, the RS determines a time interval Tad or an idle time R_IdleTime according to a predetermined scheme, and transmits the Tad or the R_IdleTime to the BS. The proposed apparatus and method reduce an overhead of a frame structure when the RS transitions from a transmission mode to a reception mode or from a reception mode to a transmission mode, the frame structure being for frames of the BS and it adjacent RS, thereby reducing interference.

摘要： An apparatus and method for reduces an overhead caused by an operation transition gap in a Relay Station (RS) of a relay wireless communication system. The method includes identifying a signal delay time with an upper node. A transmission/reception operation transition time is determined through a negotiation with the upper node. An idle time is identified. An overhead caused by a transmission/reception operation transition is determined with consideration of a start time point of an Uplink (UL) subframe dependent on the signal delay time, the transmission/reception operation transition time, and the idle time. And communication is performed considering the overhead. The start time point of the UL subframe is set earlier than a start time point of a UL subframe of the upper node in consideration of the idle time.

摘要： An apparatus and method for canceling ISI in a broadband wireless communication system are provided. In a transmitter of the broadband wireless communication system, a controller acquires a CP length, a puncturing pattern, and a time sample interval according to a delay spread. A puncturer punctures coded data in the puncturing pattern. An IFFT processor IFFT-processes the punctured coded data and outputs sample data. A CP inserter generates an OFDM symbol by inserting a copy of a last part of the sample data before the sample data. Here, the length of the last part of the sample data is equal to the CP length. A D/A converter converts the OFDM symbol to an analog signal at a sampling rate determined by the time sample interval.
