TONE INTERLEAVING METHODS FOR MULTI-BANDS AND WIDE BANDWIDTH TRANSMISSIONS IN WLAN
First Claim
1. A method of tone mapping for WLAN transmissions, the method comprising:
- dividing a wireless channel into a plurality of subcarriers, wherein the wireless channel comprises a wireless bandwidth of 320 MHz, wherein the wireless channel is operable to carry WLAN transmissions comprising codewords, and the codewords comprise a plurality of complex constellation points; and
mapping each complex constellation point of the codewords of the WLAN transmissions to tones of subcarriers of the plurality of subcarriers, wherein consecutive complex constellation points of codewords are mapped to nonadjacent tones of a respective subcarrier by;
a) mapping a first complex constellation point of the codewords to a first tone of a first subcarrier of the plurality of subcarriers;
b) mapping a second complex constellation point of the codewords to a second value of the first subcarrier;
c) mapping a third complex constellation point of the codewords to a third value of the first subcarrier;
d) mapping a fourth complex constellation point of the codewords to a fourth value of the first subcarrier;
e) repeating steps a)-d) for each subcarrier of the plurality of subcarriers; and
f) repeating step e) until all tones of the plurality of subcarriers have been mapped.

Abstract
Embodiments of the present invention provide a method and apparatus for tone interleaving wide channel bandwidths or transmissions using multiple-bands. Embodiments of the present invention are designed to accommodate new generations of WLAN. According to some embodiments, existing communication standards of the current generations of WLAN are used to simplify the implementation of the tone mapping schemes described herein. For example, some embodiments of the present invention use an 80 MHz channel bandwidth with resource units having 996 tones as a building block to efficiently implement new tone mapping and interleaving schemes for wider bandwidth channels.
