Hi Alfred,
On behalf of my colleague You-Wei Chen, could you please add the followings to PHY SP queue?
SP#1 (DCN#24/1695r1):
- Do you support the following signaling design for MU MIMO user info field?
- When Coding field indicates LDPC, then 2XLDPC indication:
- Bit22 set to 1: TX encode LDPC using code size as 2x1944
- Bit22 set to 0: TX encode LDPC using code size of 648, 1296, or 1944.

SP#2 (DCN#24/1695r1):
- Do you support the following signaling design for non-MU MIMO user info field?
- UEQM indication
- Bit19 set to 1: UEQM is applied, B20-21 are redefined to indicate UEQM patterns.
- Bit19 set to 0: EQM is applied. (B20 and B21 are Bfed and Coding bits)
- When Coding field indicates LDPC, then 2XLDPC indication:
- Bit22 set to 1: TX encode LDPC using code size as 2x1944
- Bit22 set to 0: TX encode LDPC using code size of 648, 1296, or 1944.
Thanks,

Hi Alfred,
On behave of my colleague You-Wei, please add the followings to the PHY Motion list (Mover: You-Wei Chen):
Motion 1: Move to include the following text to the 11bn SFD (DCN# 11-24/1582r2):
For the maximum number of spatial streams supported for reception of sounding NDP in UHR and the maximum total number of streams (across all users) supported for reception in UHR DL MU-MIMO and COBF PPDUs:
• 4 is mandatory except for Non-AP STA with 20 MHz-Only Limited Capabilities Support subfield equal to 1.
• 8 is optional for DL MU-MIMO and sounding NDP (Note: More than 4 is not allowed for COBF PPDUs)
Result: No objection
Motion 2: Move to include the following text to the 11bn SFD (DCN# 11-24/1582r2):
•The COBF sequential sounding support to be conditional mandatory if the device supports COBF
Result: No objection
Thanks,
Shengquan
