METHOD FOR GENERATING AND TRANSMITTING FRAME IN A WIRELESS LOCAL AREA NETWORK AND APPARATUS FOR THE SAME

摘要

PURPOSE: A method for generating and transmitting a frame in a wireless local area network and an apparatus for supporting the same are provided to provide high reliability and an efficient service to a sensor network which demands a wide coverage by expanding the service coverage of a wireless LAN system. CONSTITUTION: A short training symbol for coarse frequency offset estimation and timing synchronization is transmitted to a reception STA(Station). A long training symbol for fine frequency offset estimation and channel estimation is transmitted to the reception STA. A first signal symbol including control information is transmitted to the reception STA. A second signal symbol including the control information is transmitted to the reception STA. A first data symbol is transmitted to the reception STA. A second data symbol is transmitted to the reception STA.
