Hi Alfred,
Please add the following PHY motions as well:
- Move to add the following text to the 11bn SFD:
- For 160 MHz and 320 MHz PPDUs, in only the non-punctured primary 80 MHz subblock, the following distribution bandwidth mode is allowed
for DRU
- 20 MHz + 20 MHz + 40 MHz (or 40 MHz + 20 MHz + 20 MHz)
- Move to add the following text to the 11bn SFD:
- For distributed transmission, apply global CSD to UHR-STF only, and UHR-LTF and data still apply local per stream CSD, just like RRU.
- Move to add the following note into the 11bn D0.1, under the section “38.3.2.x RU and MRU restrictions for 20 MHz operation”:
- NOTE – When a 20 MHz operating STA participates in an 80 MHz or wider UHR TB PPDU using 20 MHz distribution bandwidth, the TX LO leakage of the STA might
interfere with some of the data subcarriers within the 20 MHz distribution bandwidth such that for some DRUs in that 20MHz DBW performance of high MCS may be significantly degraded.
Supporting documents: [25/0100r0]
Results: no objections for all

Hi Alfred,
Please add the following PHY motions as well:
- Move to add the following text to the 11bn SFD:

section of sequential sounding.
- Move to add the following text to the 11bn SFD:
- 2 BSS colors are indicated in the preamble of a COBF PPDU.
- One BSS color for the sharing AP and another BSS color for the shared AP
Supporting documents: [24/1822r4]

Hi Alfred,
Please add the following to the PHY motion list:
Move to include the following text to the 11bn SFD:
1-bit indication in the per-user SIG field to resolve the BSS color for COBF transmissions.
- The coding bit is re-purposed for this indication
([DCN#: 11-24/1829r2, 11-24/1822r4])
Passed without any objection
Thanks,
Shengquan
Hi Alfred,
Please add the motion on LDPC Enhancement PDT to the list of motions:
Move to incorporate the proposed text changes as in 11-24/1992r3 to the latest TGbn draft
The SP was passed without objection during the PHY session at Kobe meeting on 13 Jan, 2025.
Regards,
Rethna
Updated Agenda
here: please check and let me know if i missed anything.
Motion Deck
here: same. Planned round one of motions is scheduled tomorrow so let me know ASAP of any issues.
PS: Please remember that SPs do not pass or fail and are used for gathering information from the group that can be used for consensus building.
