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.

摘要： An apparatus for bidirectional communication using one or more auxiliary bands in a wireless communication system is provided. A primary band transmitter transmits data over one or more primary bands in a frame. A primary band receiver receives data over the one or more primary bands in the frame. An auxiliary band transmitter transmits data over one or more first auxiliary bands in the frame. An auxiliary band receiver receives data over the one or more first auxiliary bands or over the one or more first auxiliary bands and one or more second auxiliary bands in the frame. Therefore, it is possible to facilitate a low-delay service and to cope with a rapid channel change due to high-speed movement.

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 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： Provided is a handover method of a wireless communication system using a hierarchical cellular scheme. In the method, signal quality of a serving node is measured, so that whether to start scanning for a handover is determined. When the scanning for the handover starts, signal qualities of a serving cell including the serving node and one or more neighbor cells are measured through a first preamble including a first identifier for distinguishing a cell. An intra-cell handover or an inter-cell handover is selected using the signal qualities of the serving cell and the neighbor cells. Therefore, a terminal can easily distinguish between the inter-cell handover and the intra-cell handover, and an overhead during a handover can be reduced because an intra-cell handover procedure is simplified.
