Abstract
Presented herein is a tone plan that can accommodate multiple bandwidth options. This tone plan may be designed around a fundamental tile, such as 20 MHz tile, that is replicated to 40 and 80 MHz (and 160 MHz and beyond). For wider bandwidths, the otherwise-unused guard tones between the 20 MHz tiles are filled by a new resource unit and DC tones. There are DC tones placed to support any client, for all defined and plausible future values of its current operating bandwidth and center frequency (i.e. any 20 MHz, any 40 MHz, any 80 MHz, 160 MHz and 80+80 MHz, 320, 160+80 etc.), as well as plausible future preamble puncturing cases.
