摘要： An apparatus is provided for transmitting uplink fast feedback information in a wireless communication system. In the apparatus, a channel encoder generates uplink fast feedback information to transmit, and outputs 3-bit codewords being set according to the fast feedback information. A noncoherent modulator modulates transmission symbols corresponding to the codewords using a noncoherent modulation scheme, and allocates the modulated transmission symbols to each of subcarrier bundles. An inverse fast Fourier transform (IFFT) unit IFFT-processes a transmission signal comprised of the subcarrier bundles before transmission.

摘要： A method for transmitting and receiving broadcast signals in a radio broadcasting communication system is provided together with an associated apparatus. The transmitting method includes creating a frame having a preamble slot, a data slot and a control slot, and sending the created frame. The control slot has information for assigning the data slot to one of an uplink and a downlink. The receiving method includes receiving such a frame wherein the control slot has scheduling information for each user, and extracting the data slot from the received frame by using the scheduling information in the control slot. These methods may realize an interactive broadcasting by separately employing broadcast signals for the uplink and downlink.
