Summary:This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to pilot tone designs that support distributed transmission. A transmitting device may modulate a physical layer convergence protocol (PLCP) protocol data unit (PPDU) on a number (M) of tones representing a logical RU associated with the legacy tone plan and may further map the M tones to M noncontiguous subcarrier indices associated with a wireless channel. The transmitting device may transmit the PPDU, over the wireless channel, with a number (N) of pilot tones each having a respective location relative to the M tones as mapped to the M noncontiguous subcarrier indices. In some implementations, the relative locations of the N pilot tones may be different than relative locations of a number (K) of pilot tones associated with the logical RU.
