2X LTF SEQUENCE FOR 320 MHZ

摘要

The present invention is characterized in that a physical protocol data unit (PPDU) is transmitted via a 320 MHz frequency in a wireless local area network system, and the long training field (LTF) of the PPDU is defined through an LTF sequence. The LTF sequence relates to a 2x LTF sequence and is defined as follows: {first sequence, zero sequence, second sequence, zero sequence, third sequence, zero sequence, forth sequence}.
