Hi Woobong,

Thanks. On 1) your suggestion is good, let’s keep BW320 TBD for now.

On 3) there are a couple of places in the 11ax spec stating “The … test shall be performed over at least 20 HE PPDUs. The PPDUs under test shall be at

least 16 data OFDM symbols long”.

Regards,

Ron

Hi Wook bong

A few more comments:

1. LO requirements are copied from 11ax but we have new BW320. Suggest to keep that TBD.

[WB] You mean make texts in section xx.3.19.4.2 TBD? Or you want to keep it but want to add text something like “The transmit center frequency leakage for CBW320 PPDU is TBD”

2. Need to rows for 4K QAM

[WB] Done. Now I have 4KQAM ¾ and 5/6.

3. Need to add # of frames, # of symbols, # of PPDU for measurements

[WB] Can you clarify your comment? Maybe you can point me which text from 11ax is missing in the draft.

Thanks,

Ron

Hi, Wookbook and MJ

Thank you for sharing and updating the document.

Some modification in the attached.

It is very minor, so you may want to apply it when additional updates are implemented.

Regards,

Yujin

CAUTION: This email originated from outside of the organization.

Hi all,

I just uploaded draft text proposal for PDT-PHY- Transmit specification: Clock frequency and modulation accuracy.

11-20/1252r0 PDT-PHY-Frequency Tolerance

11-20/1253r0 PDT-PHY-Modulation Accuracy

Please let us know if you have any comment.

Thanks MJ for your work.

Best regards,

Hello all,

This is for PHY- Transmit specification: Clock frequency and modulation accuracy.

As you can find in 11ax spec, we have following two sections for this.

34.3.19 – Transmit specification
- 34.3.19.3 Transmit center frequency and symbol clock frequency
- 34..3.19.4 Modulation accuracy
  - 34.3.19.4.1 Introduction to modulation accuracy tests
  - 34.3.19.4.2 Transmit center frequency leakage
  - 34.3.19.4.3 Transmitter constellation error

There is one motion for these sections, i.e.

802.11be supports -38 dB as the Tx EVM requirement for 802.11be 4096 QAM.

[Motion 112, #SP20, [9] and [70]]

I have few things to discuss. For those thing, I am thinking we can make it TBD. Will write a contribution to discuss that.

Other than that, mostly it will be similar to 11ax.

MJ kindly volunteered for writing above sections.

He will share draft when it is ready.

If you have any suggestion, please let us know.

Best regards,

Wook Bong Lee
