Wireless transmissions using distributed tones

A wireless communication device, comprising:

• a processing system configured to:
• select a first resource unit (RU) of a plurality of RUs for transmitting a physical (PHY) layer convergence protocol (PLCP) protocol data unit (PPDU) over a wireless medium, the first RU including a set of contiguous tones occupying a first frequency bandwidth, the plurality of RUs collectively spanning a second frequency bandwidth greater than the first frequency bandwidth;
• and
• map the set of contiguous tones of the first RU to a set of non-contiguous tones distributed across the second frequency bandwidth using a tone mapping vector and a tone mapping offset associated with the first RU, the tone mapping vector indicating a starting tone index and an ending tone index of the set of non-contiguous tones;
• and
• an interface configured to:
• output the PPDU for transmission over the set of non-contiguous tones distributed across the second frequency bandwidth.
