This disclosure provides systems, methods, and apparatuses for wireless communication. An example apparatus selects a resource unit (RU) for a physical (PHY) layer convergence protocol (PLCP) protocol data unit (PPDU). The selected RU includes a set of contiguous tones spanning a bandwidth. The apparatus maps the set of contiguous tones to a set of non-contiguous tones distributed across the frequency spectrum, and transmits the PPDU over the set of non-contiguous tones. Another example apparatus selects an RU of a group of RUs that collectively span a frequency spectrum, and formats a PPDU based on a first frequency bandwidth wider than the selected RU's bandwidth. The apparatus parses the contiguous tones of the selected RU to a set of non-contiguous tones spanning a unique segment of a second frequency bandwidth wider than the first frequency bandwidth, and schedules a transmission of the PPDU over the set of non-contiguous tones.
