Re: [STDS-802-11-TGBN] PHY Motions request for May 2025

Hi Alfred,

 

Please add the following motion to the motion list. It passed SP in one of the teleconference call.

 

 

Move to include the following text in the 11bn SFD:

  • In Coordinated Spatial Reuse, the following information shall be carried in the Trigger frame that initiates concurrent CSR transmissions:
    • The transmit power limit of the shared AP
      • The shared AP Tx power limitation indicated by the sharing AP should not be lower than the minimum TX power indicated by the shared AP in its request.
    • The transmit power of the sharing AP

 

Supporting docs: 23/1868r2; 24/2060r1; 25/254r0

 

 

Best,

Jason

Hi Alfred

 

Please add the following 4 SPs to the PHY Motion list (from 25/0734r1, all passed with no objection):

 

Motion 1: Move to add the following into the 11bn SFD:

APs exchange the following 2-bit capability fields with values 1,2,3 or 4 at the time of group formation between the members of a COBF pair. The capabilities are defined for the AP declared BW and assume Nc=2 (# of columns in the feedback)

    • Field 1 – Total number of OBSS sounding reports that the AP can store for this COBF pair at a given time
    • Field 2 – Total number of OBSS joint sounding reports that the AP can store for this COBF pair at a given time (can’t be higher than number in field 1)

 

Motion 2: Move to add the following into the 11bn SFD:

In the TB PPDU carrying OBSS AP sounding feedback do you support limiting Nss to 1

 

 

Motion 3: Move to add the following into the 11bn SFD:

In COBF, cross-BSS/joint sounding feedback max Nc is limited to 2

 

Motion 4: Move to add the following into the 11bn SFD:

In TB PPDU carrying cross BSS (including joint) sounding feedback for COBF the T_PE is fixed as 20uS (nominal_packet_padding=20uS and aFactor=4) and LDPC extra symbol set as 1

AP will set the UL length field and other parameters in the BFRP trigger frame according to this rule

 

 

Thanks,

Ron

Hi Alfred,

 

Please help to add the following passed SPs to the PHY Motion list:

  • Motion 1: Move to add the following to 11bn SFD:

The definition for the transmit constellation error in an UHR TB PPDU using RRU:

Transmit Constellation Error requirement of UHR TB PPDU using RRU for MCS0-15 follows the same definition as in EHT.

Transmit Constellation Error requirement of UHR TB PPDU using RRU for the new MCSs (QPSK 2/3, 16QAM 2/3, 16QAM 5/6 and 256QAM 2/3) is:

 

MCS

Relative constellation error in an UHR TB PPDU using RRU when transmit power is larger than the maximum power of UHR-MCS 7 (dB)

Relative constellation error in an UHR TB PPDU using RRU when transmit power is less than or equal to the maximum power of UHR-MCS 7 (dB)

QPSK 2/3

-13

-27

16QAM 2/3

-18

-27

16QAM 5/6

-20

-27

256QAM 2/3

-29

-29

 

Reference document: [11-25/843r0]

Result: no objection

 

  • Motion 2: Move to add the following to 11bn SFD:

The unused tone EVM definition and requirement of UHR TB PPDU when all users are scheduled with RRU is the same as in EHT TB PPDU.

Reference document: [11-25/843r0]

Result: no objection

 

 

Thanks,

Ying
