METHOD AND APPARATUS FOR TRANSMITTING DATA FRAME IN WLAN SYSTEM

摘要

A method for transmitting data frames in a WLAN system is provided. The method includes: obtaining transmission opportunity (TXOP) which a transmitter commands a time period having a right to transmit at least one data frame and an available bandwidth for the TXOP; and transmitting data frames to at least one recipient during the TXOP sequentially. A bandwidth of the subsequent data frame among the data frames is equal to or narrower than the bandwidth of the preceding frame among the data frames.
