DATA PACKET TRANSMISSION METHOD AND APPARATUS IN WIRELESS LOCAL AREA NETWORK

摘要

Provided is a data packet transmission method applied in a wireless local area network (WLAN), the method comprising: a sending station generates a data packet comprising a preamble field and a data field, the preamble field comprising a traditional signaling field and a high-efficiency signaling field, a length field in the traditional signaling field carrying a second indication value, the second indication value being obtained after the sending station processes a first indication value, the first indication value indicating a transmission time length of the data packet, the second indication value being an even number and not being a multiple of three; the sending station sends the data packet carrying the second indication value. Also provided in an embodiment of the present invention is a corresponding data packet transmission apparatus. Applying the method and apparatus of the embodiment of the present invention shortens the length of the data packet, reduces cost and increases robustness of checking a traditional signaling field.
