Hi Alfred,
Please add the following motions which are based on SPs in yesterday’s AM1 PHY session:
- Move to include the following into 11bn SFD：
IM pilots are only applied for non-punctured/full bandwidth SU transmission.
(Result: no objection), Mover: Shengquan Hu
- Move to include the following into 11bn SFD：
when IM is applied, the value of D_TM for LDPC tone mapper is as below:
- 9 for 242-tone RU for non-DCM，
- 9 for 484-tone RU for non-DCM，
- 10 for 996-tone RU for non-DCM (same value is used for each 80MHz frequency subblock when PPDU bandwidth is 160MHz and 320MHz)
(Result: no objection), Mover: Shengquan Hu
- Move to include the following into 11bn SFD:
IM pilots have values of 0’s (i.e. Zero-Energy)
(Result: no objection), Mover: Shengquan Hu
- Move to add the following into 11bn SFD:
Nsd_short values when IM pilots are applied are as shown in the Table below
(Result: no objection), Mover: Shengquan Hu
- Move to add the following into 11bn SFD:
The number of spatial streams is defined as below if IM is used:
- For DL: limited to one spatial stream
(Result: no objection), Mover: Shengquan Hu
- Move to add the following into 11bn SFD:
IM is not applicable when MCS 15 is used.
(Result: no objection), Mover: Shengquan Hu
The supporting material for all three is DCN 25/0079r1.
Thanks,
Jianhan

Hi Alfred,
Please add the following motions which are based on SPs that passed in yesterday’s AM1 PHY session:
-
Move to include the following in TGbn SFD:
When IM is used, the LDPC tone mapper operates on both data and IM pilot tones.
(result: 72Y/7N/15A) -
Move to include the following in TGbn SFD:
The IM pilots are located contiguously at the input to the LDPC tone mapper, before the data QAMs.
(result: no objection)
3.
Move to include the following in TGbn SFD:
The number of IM pilots is
-
26 for a 242-tone RU
-
52 for a 484-tone RU
-
98 for a 996-tone RU
-
2x98 for a 2x996-tone RU
-
4x98 for a 4x996-tone RU
(result: no objection)
The supporting material for all three is DCN 25/1329r1.
Thanks,
Shimi

Hi Alfred,
Can you please either add or remove the content in Motion 473 PHY SFD with the following PDT material in 25/1315:
TGbn editor: Please add in 11bn D0.3 section
38.3.15.11.1
page 290 line 22:
In an OFDMA UHR MU PPDU using MU-MIMO in at least one RU or MRU, the total number of UHR-LTF symbols shall be chosen from the set
{2, 4, 8}.
Agreed with no objection in the PHY ad-hoc today.
Thanks,
Ron
