A station and method for transmitting a data frame in a wireless local area network are provided. The method includes obtaining, by the station, a transmission opportunity (TXOP) for a bandwidth, the TXOP indicating an interval of time when the station has a right to exchange frame sequences; selecting, by the station, a transmit bandwidth parameter of a non-initial data unit of a plurality of data units from available bandwidth parameters, wherein the available bandwidth parameters include a first available bandwidth parameter which is same as a transmit bandwidth parameter of a preceding data unit of the plurality of data units and a second available bandwidth parameter which is narrower than a transmit bandwidth parameter of the preceding data unit; and transmitting, by the station during the TXOP, the non-initial data unit according to the transmit bandwidth parameter of the non-initial data unit. |
