Methods and apparatuses are disclosed for communicating over a wireless communication network. One such apparatus may include a memory and a processor configured to identify a transmission mode for a transmission of a signal; select a tone plan for transmission of the signal within a 320 MHz total channel bandwidth or a 240 MHz total channel bandwidth, where the tone plan includes a 256 point tone plan, 512 point tone plan, 1024 point tone plane, 2048 point tone plan, 4096 point tone plan, and where the tone plan is selected based on the transmission mode; generate the signal according to the tone plan; and transmit the signal over the 320 MHz total channel bandwidth or over the 240 MHz total channel bandwidth. The selected tone plan may include one or more duplicates of an IEEE 802.11ax 80 MHz (HE80) tone plan which may include one or more null space 26 tone resource units.
