The baseband processor performs baseband processing with data received from the modulator. The RF receiver converts sample data received from the baseband processor into an analog signal and converts the analog signal into an RF bandwidth signal. The HARQ controller monitors response signals fed back from the receiver and determines retransmission according to the response signals.

Abstract: An apparatus and a method for scheduling for collaborative spatial multiplexing technique in a broadband wireless communication system are provided to couple a terminal having superior channel quality during the scheduling, thereby maximizing resource usage efficiency without a problem that a load at a specific resource area increases.

Abstract: A method and an apparatus of an automatic repeat request in a broadband wireless communication system supporting multi-hop are provided to prevent a buffer in an RS(Receiver Server) from being overflown by preventing a simple feedback between a BS(Base Station) and an MS(Mobile Station). A relay node receives data blocks from a source node and delivers the data blocks to a destination node. A first number, the smallest BSN(Block Sequence Number) of the data block delivered to the destination node, is compared with a second number, the smallest BSN fed back from the destination node(601). A third number, the biggest BSN fed back from the destination node to the relay node, is compared with a fourth number, the biggest BSN received from the source node(603). When the first and second numbers are matched and the third and fourth numbers are matched(607), an ARQ message to be transmitted to the source node is generated by using the smallest and biggest BSNs from the source node, and the ARQ(Automatic Repeat Request) message is transmitted(609).

An apparatus for receiving signals in a communication system comprises a demodulator(213), a controller(227), a channel estimator(215), and a selector(217).

Afterwards, the demodulator(213) receives a signal through the frequency domain and demodulates the received signal. The controller(227) estimates a modulation scheme, which a neighbor BS will apply to the frequency domain, by using the received signal and determines the estimated modulation scheme as the second modulation scheme. The channel estimator(215) estimates the received signal and creates channel state information. The selector(217), based on the channel state information and the information about the first and second modulation schemes, selects whether to use an interference cancellation scheme.
