Method And Apparatus For Transmitting/Receiving Physical Layer Protocol Data Unit

An apparatus for transmitting a physical layer protocol data unit, the apparatus comprising:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing program instructions for execution by the at least one processor to:
• generate a physical layer protocol data unit (PPDU), wherein the PPDU comprises a long training field, wherein a length of a frequency-domain sequence of the long training field is greater than a first length, and wherein the first length is a length of a frequency-domain sequence of a long training field of a first PPDU transmitted over a channel whose bandwidth is 160 MHz;
• and
• send the PPDU over a target channel, where a bandwidth of the target channel is greater than 160 MHz.
