Hi Youhan, Thanks for your response. How about this updated text? in the unit of dBm/20 MHz is the normalized received signal power measured at the
antenna connector in at least one 20 MHz subchannel. The measured 20 MHz subchannel(s) shall be the subchannel(s)
in which the preamble of both the PSRR PPDU and the PSRT PPDU are present. The measurement method is implementation dependent. Zinan From: Youhan Kim <youhank@xxxxxxxxxxxxxxxx> --- This message came from the IEEE 802.11 Working Group Reflector ---
Thanks, Zinan and Ross.
A punctured subchannel must not have any signal present, including any preamble. Therefore, if there is preamble present in a 20 MHz channel, then that 20 MHz channel cannot be a punctured subchannel.
As you pointed out, it is not practical to assume that a STA would know which 20 MHz channel(s) would be used for PSRT PPDU transmission while receiving a PSRR PPDU. That is why my proposed text said “at least one 20 MHz subchannel in which the preamble of both the PSRR PPDU and the PSRT PPDU are present”. Since a STA would
transmit a PSRT PPDU using at least the primary 20 MHz channel included, a reasonable/practical implementation measuring the signal power of a PSRR PPDU at the primary 20 MHz channel of the STA would still be able to transmit the PSRT PPDU in this case. In your proposed text, however, there is a “shall” requirement that the signal power of PSRR PPDU is measured over the subchannels used by the PSRT PPDU. I.e., your proposal actually requires that a STA knows
the PSRT PPDU BW when receiving a PSRR PPDU. Hence, I prefer my proposed language. Thanks. Youhan From: Yujian (Ross Yu) <00001792b51ef4ea-dmarc-request@xxxxxxxxxxxxxxxxx>

Youhan, Thanks for your suggestions. I have a few in line comments
on your suggestions. Best, Zinan From: Youhan Kim <youhank@xxxxxxxxxxxxxxxx>
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]
Therefore, I would like to have the following update on the text: I still need more time to review your #2. Regards, Youhan From: Zinan Lin <Zinan.Lin@xxxxxxxxxxxxxxxx>

Hi Youhan and Ross, Per the requirement of REVme minutes (11-22/0679r0), I am resending the discussion email to the reflector. Thanks, Zinan From: Zinan Lin 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:
RPLPSRR,20MHz
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.
