Abstract: A method and an apparatus for transmitting and receiving a response signal in a wireless communication system are provided. In a method for transmitting a response signal in a broadcasting system, Acknowledgement (ACK) information for uplink packet data for each user is generated. A symbol and a subcarrier which will transmit the ACK information for each user inside a transmission frame are determined. ACK transmission related information is transmitted via a control channel inside the transmission frame. The ACK information for each user is transmitted via the determined symbol and subcarrier inside the transmission frame.

Abstract: An apparatus and a method for transmitting uplink information in a broadcasting system are provided. A repeater of a mobile broadcasting system includes a plurality of transmitting stations each transmitting a broadcast signal for at least one broadcast service, a plurality of terminals receiving the broadcast signal for the at least one broadcast service through at least one transmitting station among the transmitting stations, and the repeater, the repeated being coupled between the plurality of transmitting stations and the plurality of terminals. The repeater includes a receiving unit configured to receive uplink information from the terminals, a control unit configured to classify the received uplink information by broadcast service and to create uplink information per broadcast service, and a transmitting unit configured to transmit the created uplink information to at least one corresponding transmitting station.
