Introduction
•
In last January IEEE meeting, motion was passed to support Distributed tone RU (DRU) for a UHR
TB PPDU transmission
•
We have shared our thoughts on DRU from high level perspectives [1]:
–
dRU can boost transmission power up to 11dB, significantly enhance the spectrum efficiency
of 6GHz LPI and improve the coverage range
–
Support of distribution bandwidth 20/40/80MHz would be a good choices considering the
harvest of maximum power boost gains, use cases, flexibility and complexity
–
DRU should keep the same set of RU sizes as RRU, and each distribution BW may support
different DRU sets such as 26/52/106-tone DRU for BW20, 26/52/106/242-tone DRU for
BW40, 52/106/242/484-tone DRU for BW80
–
Hybrid mode with DRU or RRU in each 80MHz subblock can be operated for wider
BW160/320
–
DRU with distribution BW20/40 could be considered in punctured 80MHz subblock
•
In this contribution, we would like to follow up the previous discussions and seek for
alignments

RU as existing RU defined in 11ax/be) in an UHR UL TB OFDMA transmissions
o
Minimum PPDU BW for hybrid mode TBD

Slide 9
•
Do you agree to include the following text to the 11bn SFD?
–
in a punctured 80MHz frequency subblock, the only allowed distribution BWs are
20MHz and 40MHz in 11bn
- In the March 2024 IEEE meeting, the proposal to support Distributed Tone RU (DRU) for UHR TB PPDU transmission was discussed. DRU offers significant power boost, spectrum efficiency, and coverage range improvements in the 6GHz band. This document elaborates on the technical details, including supported distribution bandwidths and DRU sizes, indicating potential alignment with previous discussions. Various straw polls were conducted for input on incorporating specific text related to DRU into the 11bn SFD. The focus is on optimizing DRU configurations for better performance and compatibility within existing standards.
