Claim:
1. A method for generating a Physical Layer Convergence Protocol (PLCP) header of a data frame, the method comprising: demodulating PLCP header mode information based on a scrambling sequence of a received frame or an information element included in the received frame; and transmitting a data frame comprising a PLCP header generated based on the PLCP header mode information, wherein the PLCP header mode information includes at least one indication of Space Time Block Coding (STBC) mode indication, Short Guard Interval (SGI) mode indication, or repetition mode indication, wherein the STBC mode indication indicates Space Time Block Coding (STBC) used to generate the PLCP header of the data frame when the STBC mode indication is included in the PLCP header mode information, wherein the SGI mode indication indicates whether a guard interval used to generate the PLCP header of the data frame is a Long Guard Interval (LGI) or a Short Guard Interval (SGI) when the SGI mode indication is included in the PLCP header mode information, and wherein the repetition mode indication indicates whether or not the PLCP header of the data frame has been repeatedly generated when the repetition mode indication is included in the PLCP header mode information, wherein the STBC mode indication is demodulated based on B wherein the SGI mode indication is demodulated based on B wherein the repetition mode indication is demodulated based on B
