DATA TRANSMISSION METHOD IN A WIRELESS LAN SYSTEM CAPABLE OF ALLOWING A LEGACY USING A CHANNEL BANDWIDTH OF 20MHZ TO COEXIST WITH A STATION USING THE CHANNEL BANDWIDTH OF OVER 80MHZ AND AN APPARATUS THEREOF

摘要

PURPOSE: A data transmission method in a wireless LAN system and an apparatus thereof are provided to reduce complexity and operation costs of a station by improving a transmission signal characteristic.;CONSTITUTION: A transmission information field includes at least one of frame timing acquisition information, channel estimation information, and data demodulating and decoding information. The transmission information field is generated. A plurality of converted transmission information fields is generated by multiplying a conversion sequence with the transmission information field. Each of the plurality of converted transmission information field is transmitted through each of a plurality of frequency blocks(410-440). The conversion sequence includes a plurality of conversion values. The plurality of converted transmission information fields is generated by multiplying a plurality of conversion values with the transmission information field.;COPYRIGHT KIPO 2012
