METHOD OF MULTIPLE FRAME TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM AND TRANSMITTER

摘要

PURPOSE: A method for transmitting a multiple frame in a wireless communication system and a transmitter are provided to allow other stations to use idle sub channels by adjusting the bandwidth of a data frame while request to send-clear to send(RTS-CTS) and transmission opportunity(TXOP). CONSTITUTION: A processor(11) establishes TXOP by receiving a CTS frame with a second bandwidth in response to an RTS frame. The TXOP indicates a time with authority which allows a transmitter to transmit a data frame. The processor successively transmits data frames while the TXOP. The bandwidths of the data frames are the same as or smaller than the second bandwidth. The bandwidth of a subsequent data frame is the same as or smaller than a bandwidth of a preceding data frame.
