Method and apparatus for receiving PPDU on basis of control information related to pilot tone in wireless LAN system

A receiving station (STA) in a wireless local area network (WLAN) system, the receiving STA comprising:

• a memory;
• a transceiver;
• and
• a processor being operatively connected to the memory and the transceiver,
• wherein the processor is configured to:
• receive a Physical Protocol Data Unit (PPDU) from a transmitting STA;
• obtain control information related to a tone plan and a pilot tone by decoding the PPDU;
• and
• decode a data field of the PPDU based on the control information,
• wherein the tone plan includes information on an arrangement of tones or Resource Units (RUs) used within a bandwidth of the PPDU,
• wherein based on the PPDU being transmitted based on non-Orthogonal Frequency Division Multiple Access (non-OFDMA) without puncturing and the bandwidth of the PPDU being 480 MHz, the tone plan is a 6×996-tone RU or a 3×2020-tone RU, and
• wherein indices of a first pilot tone in the 6×996-tone RU or the 3×2020-tone RU are ±{112, 246, 360, 494, 598, 732, 846, 980, 1136, 1270, 1384, 1518, 1622, 1756, 1870, 2004, 2160, 2294, 2408, 2542, 2646, 2780, 2894, 3028}.

A method in a wireless local area network (WLAN) system, the method comprising:

• obtaining, by a transmitting station (STA), control information related to a tone plan and a pilot tone;
• generating, by the transmitting STA, a Physical Protocol Data Unit (PPDU) based on the control information;
• and
• transmitting, by the transmitting STA, the PPDU to a receiving STA,
• wherein the tone plan includes information on an arrangement of tones or Resource Units (RUs) used within a bandwidth of the PPDU,
• wherein based on the PPDU being transmitted based on non-Orthogonal Frequency Division Multiple Access (non-OFDMA) without puncturing and the bandwidth of the PPDU being 480 MHz, the tone plan is a 6×996-tone RU or a 3×2020-tone RU, and
• wherein indices of a first pilot tone in the 6×996-tone RU or the 3×2020-tone RU are ±{112, 246, 360, 494, 598, 732, 846, 980, 1136, 1270, 1384, 1518, 1622, 1756, 1870, 2004, 2160, 2294, 2408, 2542, 2646, 2780, 2894, 3028}.
