METHOD AND APPARATUS FOR TRANSMITTING DATA FRAME IN WIRELESS LAN SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method of transmitting a data frame in a wireless LAN.SOLUTION: The method includes: obtaining a transmission opportunity (TXOP) indicating a time interval during which a transmitter has a right to transmit at least one data frame and an available bandwidth for the TXOP; and sequentially transmitting a plurality of data frames to at least one receiver during the TXOP. A bandwidth of a subsequent data frame of the plurality of data frames is equal to or narrower than a bandwidth of a preceding frame of the plurality of data frames which was transmitted right before the subsequent data frame.
