Hi, Sameer

Regardless of whether we start drafting the Multi AP section now, I wanted to clarify.

If you feel ok for now to include the Multi AP NDP issues I mentioned in the previous email in the Multi AP Sounding section, let me go ahead and include the following motion as one of the relevant motions to the Multi AP Sounding section.

 

“Joint NDP sounding scheme for multi-AP system with less or equal to total 8 antennas at AP has all antennas active on all LTF tones and uses 802.11ax P matrix across OFDM symbols.

[Motion 15, [3] and [143]]”

 

The motion 15 above was not listed as a relevant motion in the Multi AP Sounding section yet, because I thought that the motion 15 may belong to your section. But, let me go ahead and add the motion 15 to the Multi AP Sounding Section.

 

Let me know if you have a different opinion.

 

Regards

Junghoon

Hi Junghoon,

 

Thanks for your e-mail. Hopefully the PPDU format for joint sounding NDP can stay the same as the regular NDP so that we don’t need much multi-AP related additions in this section. However, we can discuss about the proper place for things you mention as more decisions get made on this topic and multi-AP sounding.

 

Regardless, I do think we are not yet ready to start drafting this section.

 

Regards,

Sameer

Hi, Sameer

Thank you for taking an initiative on spec draft writing for this section.

As I asked during the call today, I wanted to clarify the Multi AP Sounding NDP case, such as  the LTF design for Joint sounding NDP transmitted from coordinated APs simultaneously, indication of global number of LTFs or Streams across coordinated APs in NDP, etc.

 

I am the PoC of Multi AP Sounding section, and I even wonder if I need to include the issues I mentioned above in the Multi AP Sounding section which I take as a PoC or in the EHT Sounding NDP which you take as a PoC.

 

Regards

Junghoon

Hi  ‘EHT Sounding NDP TTT members’ and all,

 

EHT Sounding NDP section in PHY will mainly cover the NDP PPDU format details.  As the POC for this section, I plan to draft the spec text and then have a discussion with TTT members.  Considering lack of motions related to this section so far, the spec drafting needs to wait for agreements to be made on this topic.

 

Let me know if you have any comments or suggestions.

 

Regards,

Sameer
