A broadband wireless communication system supporting frequency overlay is provided. Operations of a base station includes checking whether it is time to transmit a common control signal; switching positions of a first Common Control Channel and a second Common Control Channel applied to a previous transmission of the common control signal while mapping a common control signal to the first Common Control Channel and the second Common Control Channel positioned in different Frequency Assignments; and transmitting the common control signal via the first Common Control Channel and the second Common Control Channel that are switched.

A method to transmit a packet of a BS in a communication system using a HARQ scheme is provided. The method includes assigning resource for transmitting a packet to a mobile station, and transmitting a first packet to the mobile station using the assigned resource; transmitting timing information on which a second packet is transmitted to the mobile station when the BS does not receive information indicating that the mobile station decoded the first packet successfully or when the BS receives information indicating that the mobile station failed to decode the first packet; and transmitting the second packet to the mobile station on a timing point corresponding to the timing information.

Disclosed is a method of transmitting common control information by a base station in a communication system including a first communication system and a second communication system different from each other. In the communication system, a frame for carrying the common control information includes an uplink sub-frame and a downlink sub-frame, each of which includes a resource allocation area for the first communication system and a resource allocation area for the second communication system. The method includes: configuring the common control information to be received by a mobile station belonging to the second communication system; and transmitting the common control information through the resource allocation area for the second communication system included in one of the uplink sub-frame and the downlink sub-frame.

An apparatus and method for performing Automatic Retransmission reQuest (ARQ) of a Relay Station (RS) in a wireless communication system using a relay scheme are provided. The method includes receiving data from a transmitter and transmitting the received data to one or more receivers; and receiving Acknowledgment (ACK)/Negative-Acknowledgment (NACK) information for the data received from the one or more receivers and transmitting the received ACK/NACK information to a Base Station (BS).
