Second, for intended BSS color indication is only for Co-BF based on motion 214,

So, maybe we can update your suggested text as (based on the intended BSS color indication if Co-BF is used).

I also noticed that motion 214 is not captured in D0.2. I have contacted PoC of the UHR-SIG, Mengshi, regarding this issue.

So, the name “intended BSS color indication” may be updated. Or we can suggest to use that name to Mengshi.

Lastly, regarding spatial reuse, I am not sure whether it is a good idea to allow spatial reuse on Co-BF/Co-SR and ELR PPDU.

I think we need to have further discussion on it.

— If the CRC protecting ELR-SIG1 is valid, the UL/DL does not contain an intended value, the PHY entity shall issue a PHY-RXSTART.indication(RXVECTOR) then issue a PHY-RXEND.indication(Filtered). The PHY shall maintain PHY- CCA.indication(BUSY, channellist) primitive for the predicted duration of the transmitted PPDU derived from the LENGTH field in ELR-SIG1 as defined in Equation (38-110) ~~unless it receives a PHY- CCARESET.request primitive before the end of the PPDU for instance during spatial reuse operation as described in 37.10 (UHR Spatial reuse operation)~~.

— If the CRC protecting ELR-SIG1 is valid and the UL/DL contains an intended value, the PHY shall continue to check CRC of ELR-SIG2

— If the CRC protecting ELR-SIG2 is not valid, the PHY shall issue the error condition PHY-RXEND.indication(FormatViolation) primitive and maintain PHY- CCA.indication(BUSY, channellist) primitive for the predicted duration of the transmitted PPDU derived from the LENGTH field in ELR-SIG1 as defined in Equation (38-110) ~~unless it receives a PHY- CCARESET.request primitive before the end of the PPDU for instance during spatial reuse operation as described in 37.10 (UHR Spatial reuse operation)~~.

— If the CRC protecting ELR-SIG2 is valid, the STA-ID in ELR-SIG2 does not match the 11 LSBs of the AID of a STA in theAP’s BSS, then the PHY entity shall issue a PHY-RXSTART.indication(RXVECTOR) then issue a PHY-RXEND.indication(Filtered). The PHY shall maintain PHY- CCA.indication(BUSY, channellist) primitive for the predicted duration of the transmitted PPDU derived from the LENGTH field in ELR-SIG1 as defined in Equation (38-110) ~~unless it receives a PHY- CCARESET.request primitive before the end of the PPDU for instance during spatial reuse operation as described in 37.10 (UHR Spatial reuse operation)~~.

Hi PHY folks,
Thanks for the discussions yesterday.
As agreed on the call, please find the updated version as attached. I have cleaned up the "track change" and only keep the ones in Page 7 regarding the BSS color match in UHR-SIG. As I mentioned yesterday, BSS color filter has been done in U-SIG. Page 7 deals with STA-ID match in UHR-SIG. "Intended STA-ID" should be good enough IMO, but to accommodate other members I modified the current text to "an intended STA-ID (based on the intended BSS color indication if CoBF/CoSR is used) is detected" to cover CoBF/CoSR. Hope we can converge on the current version.
If I don't hear a different opinion by Thursday, the attached R2 will be uploaded to the server. Thanks.
