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: A method for providing a broadcast service is provided. The method includes transmitting a user datagram protocol (UDP)/internet protocol (IP) packet including a first message, the first message containing information about a message to be signed and transmitted, and transmitting a moving picture experts group (MPEG) media transport protocol (MMTP) packet including a second message, the second message containing information about the broadcast service and information indicating whether the information about the broadcast service is signed. The first message includes an identifier of a key used to verify a signature of the message to be transmitted and signed and an identifier of a hash algorithm used to calculate a hash value of the message to be transmitted and signed.
