Re: [STDS-802-11-TGBE] EHT PHY Agenda Item - PDT Clarification Extra LTF PHY Capability

[Steve Shellhammer <sshellha@xxxxxxxxxxxxxxxx>]

Ross,

 

                You bring up a good point.  I have revised the document (now 755r1), and dropped the text on “non-OFDMA” in the description of bits B3-B4.

 

                Thanks for reminding me of that motion.

 

Regards,

Steve

Hi Steve,

 

Then how about the OFDMA case?

 

We have the following motion:

The allowed values of maximum N_LTF receive capability for multiple-user transmission are 4, 8, and 16.

• NOTE 1 – This capability is for both OFDMA and non-OFDMA MU-MIMO transmission. 
• NOTE 2 – The value of maximum N_LTF = 16 is available in R2.

[Motion 141, #SP261, [3] and [52]]

Hi Ross,

 

                It is my understanding that this Extra LTF PHY Capability is for the non-OFDMA mode. As you can see B0 indicates support for this feature, where it is clear that it is for the non-OFDMA case.  That is why we are providing clarifying text.

 

                The main point of the edits is to clarify this is a receiver capability, which was unclear in the original text.

 

                I hope this addresses your comment.

 

Regards,

Steve

Hi Steve,

 

B3-B4 previously covers OFDMA case, which is the case in 11ax. For OFDMA case, it indicates 8 or same as Beamformee NSTS capability.
