Method and apparatus for two-way broadcasting

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.

1. A method for transmitting a broadcast signal for a two-way communication, the method comprising:
creating, by a creating unit, a frame having at least one preamble slot, at least one data slot and at least one control slot; and transmitting, by a sending unit, the created frame, wherein the at least one control slot contains information indicating or requesting which of the at least one data slot is to be used for an uplink or a downlink, wherein the at least one data slot contains an orthogonal frequency division multiplexing (OFDM) symbol, and wherein the OFDM symbol is generated for distinguishing respective broadcasting systems by using a scrambling code.
