Hi Alfred,
Could you also add the following straw polls on NPCA to the MAC queue? They were presented in document
11-24/1218r1.
- Do you agree that an NPCA STA shall indicate the following to its peer NPCA STA?
- NPCA switching delay
- time it needs to switch from the BSS Primary channel to the NPCA Primary channel
- NPCA switch back delay
- time it needs to switch from the NPCA Primary channel to the BSS Primary channel
- Do you agree with the following:
- An NPCA STA shall initiate frame exchange on the NPCA Primary channel with an NPCA Initial Control Frame in the non-HT PPDU or non-HT duplicate PPDU format using a rate of 6 Mb/s,
12 Mb/s, or 24 Mb/s
- Details on NPCA ICF are TBD
- Do you agree that an NPCA STA shall initiate a TXOP on the NPCA Primary channel following the rules defined in 10.23.2.2 (EDCA backoff procedure) and 10.23.2.4 (Obtaining an EDCA TXOP)
with the following exception:
- Every time the STA switches to the NPCA Primary channel, it shall initialize CW_NPCA[AC] to TBD value and pick a new backoff counter (BO_NPCA) randomly between 0 and CW_NPCA[AC]. QSRC_NPCA[AC]
shall be set to 0.
- NOTE – Baseline EDCA procedure is followed on the BSS Primary channel. The values of CW_NPCA and BO_NPCA are discarded by the NPCA STA when it switches back to the BSS Primary channel.
- Do you support that after an NPCA STA has gained the right to initiate a TXOP on the NPCA Primary channel, it can transmit on a set of channels that:
- Includes the NPCA Primary channel, and
- are within the AP’s BSS bandwidth, and
- do not include the channels in the bandwidth occupied by the OBSS traffic that caused the NPCA STA to switch from the BSS primary channel to the NPCA primary channel, and
- do not include the channels that are indicated as punctured in the Disabled Subchannel Bitmap subfield in the EHT Operation element,
- It is TBD whether a frame that does not solicit TB PPDUs can puncture 20 MHz subchannels not indicated as punctured in the Disabled Subchannel Bitmap subfield of the EHT Operation
element
- Do you agree to the following:
- When soliciting an UL TB PPDU on the NPCA Primary channel, the NPCA AP shall signal the RU index considering the NPCA Primary channel as the reference primary channel
- The Trigger frame soliciting the TB PPDU shall explicitly indicate that it is transmitted via the NPCA Primary channel (details TBD)
- Do you agree to define a mode of operation in NPCA where the NPCA non-AP does not use untriggered UL transmissions on the NPCA primary channel
- This mode can be enabled/disabled by the AP
- Whether the mode is for all associated non-APs or per non-AP is TBD
- TBD whether MU EDCA parameters mechanism is used for this or not
Thanks,
Gaurang

HI Alfred,
Please queue the following SPs to the MAC queue:
- Do you support that
the event that triggers switching to the NPCA primary channel shall be
- OBSS Control frame exchange (e.g., (MU-)RTS/CTS) or
- OBSS HE/EHT/UHR PPDU
- Do you support that the NPCA operation shall use the same EDCA parameters ((MU) EDCA Parameter Set, EPCS EDCA Parameters), on both the BSS primary channel and the NPCA primary channel.
Thanks,
Laurent
