Abstract: This disclosure provides methods, components, devices and systems for reducing out-of-band emission (OOBE) for transmissions associated with a distributed resource unit (RU) (dRU) allocation. Some aspects more specifically relate to introducing more unevenness in terms of tone spacing to a first subset of dRUs associated with a given bandwidth and maintaining relatively more even tone spacing for a second subset of dRUs associated with that given bandwidth. In some implementations, for example, a complete set of dRUs associated with a bandwidth may include a first subset of dRUs and a second subset of dRUs, with dRUs of the first subset having more uneven tone spacings as compared to dRUs of the second subset. In some aspects, the first subset of dRUs may include dRUs associated with relatively fewer tones as compared to dRUs of the second subset.

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 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.
