A spatial modulation method and transmitting and receiving apparatuses using the spatial modulation method in a MIMO system are provided. The spatial modulation method uses an index of an activated antenna and a signal modulation constellation as an information source. The spatial modulation method is applied to the transmitting apparatus. The receiving apparatus uses a spatial modulation detection method in which a channel path gain is repeatedly multiplied to detect the spatially modulated signal efficiently.

A transport control method in a transmitter of a wireless communication system, which includes a transport layer having a congestion control function of transmitting data in a segment basis and retransmitting a segment if an RTO timer expires before receipt of an ACK segment is received in response to transmission of the segment and a MAC layer for detecting receipt of an ACK segment through a wireless link and transporting the detected ACK segment to the transport layer, includes temporarily storing received ACK segments in the MAC layer; detecting an average transmission rate of data segments; and transporting the stored ACK segments to the transport layer at the average transmission rate. Accordingly, by controlling an upward transport rate of a received ACK message by referring to an RTO value of a TCP in a MAC layer, unnecessary retransmission can be prevented by a congestion control function.

A system and method for transmitting resource allocation information in a wireless communication system is provided. A transmitter transmits resource allocation information mapped to a current time interval in a first region to a receiver, and transmits resource allocation information mapped to a next time interval in a second region. When receiving the resource allocation information of the second region, the receiver notifies the transmitter whether the resource allocation information has been received. The transmitter receives notification that the resource allocation information of the second region has been received and transmits resource allocation information mapped to a subsequent time interval in the second region.

A signaling method between a cognitive radio (CR) base station and a CR terminal in a CR environment, and a channel division method used for the signaling method, includes: detecting a channel usage of an incumbent system, which communicates with a CR base station; sensing an outband channel to communicate with the CR base station; receiving an EOS, which is broadcasted from the CR base station via the outband channel according to a predetermined period; and transmitting a sensing report signal with respect to the channel to the CR base station.
