WIRELESS TRANSMISSIONS USING DISTRIBUTED TONES

Abstract:

This disclosure provides systems, methods, and apparatuses for wireless communication. An example apparatus selects 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 may include a set of contiguous tones occupying a first frequency bandwidth. The plurality of RUs may collectively span a second frequency bandwidth greater than the first frequency bandwidth. The apparatus maps 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 apparatus transmits the PPDU over the set of non-contiguous tones distributed across the second frequency bandwidth.
