US 12,598,037 B2 · 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.

Dependent claims

A wireless communication device, comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the wireless communication device to:
select a first resource unit (RU) of a plurality of RUs for transmitting a data unit over a wireless medium, the first RU including a first set of tones occupying a first frequency bandwidth;
map the first set of tones of the first RU to a second set of tones evenly distributed across a second frequency bandwidth;
and
transmit the data unit over the second set of tones evenly distributed across the second frequency bandwidth.
