Method and apparatus for transceiving data

A station, comprising:

• a circuitry which is configured to:
• determine a bandwidth of a data unit;
• determine a number of bits related to a length of the data unit based on the bandwidth;
• cause the station to generate a data field based on the number of bits, wherein the data field comprises the data unit;
• cause the station to transmit a first signal field;
• cause the station to transmit a second signal field after transmitting the first signal field;
• cause the station to transmit a third signal field after transmitting the second signal field;
• and
• cause the station to transmit the data field after transmitting the third signal field.
