Method and apparatus for transmitting data frame in WLAN system

摘要

A method and station for receiving a data frame in a wireless local area network are provided. The method includes receiving, from a transmitter which has obtained a transmission opportunity (TXOP) for a bandwidth, a first data unit of a plurality of data units during the TXOP, the TXOP indicating an interval of time when the transmitter has a right to exchange frame sequences; and after receiving the first data unit, further receiving, from the transmitter, a second data unit of the plurality of data units during the TXOP, wherein a transmit bandwidth of the second data unit is selected from available bandwidths, wherein the available bandwidths include a first available bandwidth which is same as a transmit bandwidth of the first data unit and a second available bandwidth which is narrower than the transmit bandwidth of the first data unit.
