METHOD AND DEVICE FOR INDICATING PLCP HEADER TRANSMISSION MODE

摘要

Disclosed are a method and device for indicating a PLCP header transmission mode. A method for generating a physical layer convergence protocol (PLCP) header of a data frame includes the steps of demodulating PLCP header mode information based on an information element included in the received frame or a scrambling sequence of the received frame; and generating the data frame including the PLCP header generated based on the PLCP header mode information. The PLCP header mode information includes at least one indication among a space time block coding mode indication, a guard interval mode indication, and a repetition mode indication. Data transmission efficiency is improved by adaptively determining the transmission mode of the PLCP header according to a channel situation.
