Re: [STDS-802-11-TGBN] TGbn PHY Motion Request

Hi Alfred,

Could you please add the following to the PHY motion list?

Motion: Move to include the following text to 11bn SFD (DCN# 11-24/474, 11-24/498r4, 11-24/507)?

  • UHR defines unequal modulation which uses joint LDPC encoding across multiple spatial streams while at least one spatial stream uses a different modulation order compared to the first spatial stream, and is applicable only to non-MU-MIMO beamformed transmissions using 2 to 4 spatial streams in a UHR MU PPDU.
Result: No objection

Alice Chen

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

Hi Alfred,

 

  Please also add the followings to the TGbn PHY motion list:

 

Motion-1:  Move to include the following text to the 11bn SFD: (DCN# 11-24/1488r0)

 

ELR PPDU only supports the following two modulation and coding schemes:

- BPSK with coding rate R=1/2

- QPSK with coding rate R=1/2

 

Y/N/A: 61/6/9

 

Motion-2:  Move to include the following text to the 11bn SFD: (DCN# 11-24/1488r0)

ELR transmission shall apply the phase rotations as below for both BPSK and QPSK modulations

  • The rotation of -1 will be applied on data subcarriers of lower half of RU3 and upper half of RU4 for 52-tone regular RU (RRU52) on 20MHz

 

 

Passed without any objection 

 

Thanks,

Shengquan
