Abstract

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.
