Abstract: 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 short training field (STF) designs and signaling that support distributed transmissions. A transmitting device that transmits data on a distributed resource unit (dRU) may transmit an STF sequence over a spreading bandwidth of the dRU according to an existing STF tone plan.

As such, different global CSDs may be assigned to different STAs so that each STA transmits its STF sequence with different amounts of delay.
