    摘要: A method of transmitting data in a wireless communication system, includes: transmitting first data via a first frame for a first wireless communication system; transmitting second data via a second frame for a second wireless communication system supporting backward compatibility with respect to the first wireless communication system; and transmitting control information with respect to the first and second frames, wherein the control information includes a frame control header (FCH) which indicates information about the second frame by using a reserved bit region of the first frame.

    摘要: An apparatus for transmitting a synchronization signal using a plurality of transmit (Tx) antennas is provided. The apparatus includes a synchronization signal generator for generating a synchronization signal used for tracking timing or frequency synchronization, a transmission processor for allocating different subcarriers to a plurality of Tx antennas without overlapping, mapping the synchronization signal to the subcarriers, and generating an orthogonal frequency division multiplexing (OFDM) symbol by performing inverse fast Fourier transformation (IFFT), a control signal coupler for controlling codes as a resource not to overlap among the plurality of Tx antennas, and the plurality of Tx antennas for transmitting the OFDM symbol.
