Techniques for tone mapping for 60 mhz distribution bandwidth

A wireless device, comprising:

• a processing system that includes processor circuitry and memory circuitry that stores code, the processing system configured to cause the wireless device to:
• receive a physical layer convergence protocol (PLCP) protocol data unit (PPDU) over an 80 megahertz (MHz) distribution bandwidth, wherein the 80 MHz distribution bandwidth is punctured providing a 60 MHz distribution bandwidth, wherein one or more cyclic shift delays (CSDs) are respectively applied to a plurality of distribution resource units (dRUs) of the PPDU in accordance with one or more of:
• a first CSD index pattern defined for a first 60 MHz or a second 60 MHz of a 80 MHz distribution bandwidth, a second CSD index pattern defined for a first 40 MHz and a second 40 MHz of the 80 MHz distribution bandwidth, or a plurality of global CSD assignment index values associated with the 60 MHz distribution bandwidth;
• and
• obtain data from the PPDU.
