Youhan,
Thanks for your suggestions. I have a few in line
comments
on your suggestions.
Best,

Hi, Zinan.
Thank you very much for the document.

The most important thing is to be clear that the unit of RPL_{PSRR,20MHz} is dBm/20MHz. How one computes it is implementation specific, except that I agree with you that 20 MHz subchannels which are used in both the
PSRR and PSRT should be used. Therefore, my suggestion is

[ZL]
- May I know if 802.11be or 802.11ax specs specifies “preamble of PSRR PPDU is present” is equivalent to the non-punctured subchannel(s) in PSRR PPDU?
- I am concerned about requiring the preamble presence in both PSRR PPDU and PSRT PPDU. Since the formula is used to set the upper bound of PSRT PPDU transmission power, how
can the PSRT PPDU be present when the measurement is made prior to the first transmission?
Therefore, I would like to have the following update on the text:
I still need more time to review your #2.

Youhan

Hi Youhan and Ross,
Per the requirement of REVme minutes (11-22/0679r0), I am resending the discussion email to the reflector.
Thanks,

Hi Youhan and Ross,
Thanks for your comments and discussions on 11-22/0652!
Attached please find the updated document. I summarize the resolutions for the comments you made:
- The definition of
is
updated as follows:
is
the received signal power at the receive antenna connector in the nonpunctured 20 MHz subchannel in dBm. It can be the received signal power at the received antenna connector in at least one nonpunctured 20 MHz subchannel within the overlapping bandwidth of
the PSRR PPDU and the PSRT PPDU, or the received signal power at the received antenna connector in the nonpunctured 20 MHz subchannels within the overlapping bandwidth of the PSRR PPDU and the PSRT PPDU normalized to a 20 MHz subchannel. The identification
of the overlapping bandwidth is implementation dependent.
- As indicated in
26.10.3.4 (P4242L1, REVme D1.0), UL Spatial Reuse subfield of Trigger frame is defined for each 40 MHz subchannel for an 80+80MHz or 160 MHz PPDU. The Spatial Reuse subfields of HE-SIG-A field of an HE TB PPDU should follow this
definition, i.e., Spatial Reuse value is applied to 40MHz subband of the 160MHz band. Therefore, when the PSRR PPDU is 160MHz, to get PSR for 20 MHz subchannel, it needs to normalize the PSR value of the UL Spatial Reuse subfield in the Common Info field
of the Trigger frame of the PSRR PPDU to 20 MHz subchannel. The NOTE in the 11-22/0652r3 explained this already.
Please let me know your comments.
Thanks,
Zinan
