    摘要： An apparatus and method for avoiding interference between a base station and a relay station when using full duplex relay in a multi-hop relay wireless communication system are provided. An operation of a mobile station includes measuring an strength of a receive signal from a base station and an strength of a receive signal from an relay station, calculating a receive signal strength ratio of base station to relay station by dividing the strength of the receive signal from the base station by the strength of the receive signal from the relay station, determining if interference occurs using the receive signal strength ratio, and transmitting a control message representing if interference occurs.

    摘要： An apparatus and method for receiving data in a communication system. A Mobile Station (MS) receives a Base Station (BS) signal and a Relay Station (RS) signal, measures strengths of the received BS signal and RS signal, determines whether the BS signal acts as interference to the RS signal depending on the measured strengths of the RS signal and the BS signal, and transmits the determination result to an RS in communication with the MS. The RS allocates resources using resource allocation information for the BS signal that acts as interference, and the MS receives data using the resource allocation scheme allocated from the RS.

    摘要： A method for receiving multicast service data by a terminal in a communication system. The method includes receiving a pilot from a base station, measuring channel state information using the received pilot, and transmitting the channel state information to the base station; receiving a frame from the base station, and determining whether there is an error in the received frame; when no error has occurred in the received frame, determining whether the number of frames consecutively received without error is greater than or equal to a predetermined number; and when the number of frames consecutively received without error is greater than or equal to the predetermined number, transitioning to a non-feedback state where the terminal transmits no channel state information to the base station. The frame includes multicast service data.

    摘要： An apparatus and method for compensating for a phase error in a wireless communication system are provided. The apparatus includes a reception modem, a transmission modem, a Common Phase Error (CPE) compensator, a first channel estimator, a phase compensator, and a second channel estimator. The reception modem demodulates and decodes a signal received. The transmission modem encodes and modulates a signal for transmission. The CPE compensator compensates for phase errors of at least two symbols constituting a signal. The first channel estimator estimates channels for respective bursts. The phase compensator compares phases for the channels for the respective bursts with each other and compensates for a phase difference between at least two bursts. The second channel estimator estimates an interference channel.

    摘要： An apparatus and a method for mitigating interference of a neighbor cell in a multihop relay wireless communication system are provided. The method includes constituting a subframe for a link affected by interference of a neighbor cell over a first frequency band of the frame, and constituting a subframe for a link causing interference to a neighbor cell over a second frequency band of the frame. Therefore, the interference between the neighbor cells can be reduced and the amount of the resources allocated to the links can be freely adjusted.
