Abstract
A method of transmitting a data frame in a wireless local area network is provided. The method includes TXOP the step of: 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, wherein a bandwidth of a subsequent data frame of the plurality of data frames is same to or narrower than a bandwidth of a preceding data frame of the plurality of data frames which is last previously transmitted before the subsequent data frame.

21. A method of transmitting a data frame by a transmitter in a wireless local area network, the method comprising:
-
obtaining, by the transmitter, a transmission opportunity (TXOP) for a bandwidth, the TXOP indicating a interval of time when the transmitter has a right to exchange frame sequences; if a specific condition in the TXOP is determined by the transmitter to have been met, setting, by the transmitter, a transmit bandwidth parameter of a non-initial data unit of a plurality of data units to be the same or narrower than a transmit bandwidth parameter of a preceding data unit of the plurality of data units; and transmitting, by the transmitter during the TXOP, the non-initial data unit according to the transmit bandwidth parameter of the non-initial data unit. - View Dependent Claims (22, 23, 24, 25, 26)

27. A transmitter configured to transmit a data frame in a wireless local area network, the transmitter comprising:
-
a transceiver; and a controller operatively connected to the transceiver and configured to obtain a transmission opportunity (TXOP) for a bandwidth, the TXOP indicating an interval of time when the transmitter has a right to exchange frame sequences, if a specific condition in the TXOP is determined to have been met, set a transmit bandwidth parameter of a non-initial data unit of a plurality of data units to be the same or narrower than a transmit bandwidth parameter of a preceding data unit of the plurality of data units, and transmit, during the TXOP, the non-initial data unit according to the transmit bandwidth parameter of the non-initial data unit. - View Dependent Claims (28, 29, 30, 31, 32)
