摘要： A method and a station are described for transmitting a data frame in a wireless local area network (WLAN). The station obtains a transmission opportunity (TXOP) and transmits, during the TXOP, a preceding data unit of a plurality of data units comprising a control field indicating a selected bandwidth for the preceding data unit. The station selects a transmit bandwidth parameter of a non-initial data unit of the plurality of data units from available bandwidth parameters. The available bandwidth parameters include a first available bandwidth parameter which is same as a transmit bandwidth parameter of the 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. The station transmits, during the TXOP, the non-initial data unit, which comprises a control field indicating a selected bandwidth for the non-initial data unit.
