[STDS-802-11-TGBF] Offline OFDMA Discussion

Hi everybody,

 

As I mentioned during the discussion of 21-1602r0 (https://mentor.ieee.org/802.11/dcn/21/11-21-1602-00-00bf-ofdma-measurement-discussion.pptx), I wanted to open up an opportunity for any offline comments or discussion regarding the usage of OFDMA for Sensing before I run the SP.

 

One good point was raised on the need to define a partial bandwidth NDP, which would be appropriate.  I’m interested to hear any thoughts or potential concerns on doing that within 11bf.

For the HE-PHY case, equation 27-59 in the 11ax spec describes the HE-LTF of an HE TB PPDU.   From what I can tell, it constrains the definition to only subcarriers within the STAs allocated RU (e.g., subcarriers in the set Kr).

Therefore, could this be achieved within the scope of 11bf by extending the 11az TB Ranging NDP definition to allow flexibility in TXVECTOR.RU_ALLOCATION, and defining appropriate additions to the 11az MLME section describing the measurement exchange?

 

Thanks and regards,

-Chris
