Hi Alfred,

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

Motion 1: Move to include the following text to the 11bn SFD: (DCN# 11-24/1478r4)

ELR packet detection is done at L-STF, which has same length as legacy with 3dB power boosting

L-LTF also has same length as legacy with same power boosting as L-STF

Results: 49Y, 8N, 14A

Motion 2: Move to include the following text to the 11bn SFD: (DCN# 11-24/1478r4)

U-SIG carries STA-ID in ELR PPDU

Passed without any objection

Motion 3: Move to include the following text to the 11bn SFD: (DCN# 11-24/1478r4)

Define two ELR-Mark symbols for ELR mode classification

ELR-Mark symbols carry a known sequence to receiver
ELR-Mark symbols carry BSS color info in ELR-Mark sequence
No power boosting on ELR-Mark symbols
Two ELR-Mark symbols are both QBPSK modulated on data subcarriers
ELR-Mark symbols use the following tone plan

4 regular pilots as EHT-SIG + 48 data tones

Passed without any objection

Motion 4: Move to include the following text to the 11bn SFD: (DCN# 11-24/1478r4)

11bn defines the following PPDU frame format for ELR

PE TBD

Passed without any objection

Motion 5: Move to include the following text to the 11bn SFD: (DCN# 11-24/1478r4)

ELR PPDU has 3dB boosting applied on both ELR-STF and ELR-LTF

ELR PPDU has ELR-STF duration and sequence same as that of UHR DL SU/MU PPDU

4us using EHT-STF sequence for 20MHz

ELR PPDU defines a fixed/single mode of LTF+GI

11bn supports 2x LTF+1.6us GI only for ELR PPDU
11bn uses two UHR-LTF symbols for ELR PPDU

Note that ELR-STF/ELR-LTF are the short names of UHR-STF/UHR-LTF for ELR PPDU

Passed without any objection

Motion 6: Move to include the following text to the 11bn SFD: (DCN# 11-24/1478r4)

ELR PPDU defines two symbols for ELR-SIG, specifically

ELR PPDU defines separately encoded two symbols for ELR-SIG

Each symbol has separate CRC and tail bits (6 bits)

ELR-SIG has same tone plan and duplication scheme as ELR-data and BCC encoded with MCS0

Passed without any objection

Thanks,

Lin

Hi Alfred,

Can you please add the following PHY motions to the motion list?

Do you agree to add following text to the TGbn SFD? (DCN #11-24/1573r1)

Define an enhanced long range (ELR) PPDU in IEEE 802.11bn with the following targets

Downlink and Uplink in 2.4 GHz (within BSS range with 11b beacon)
Uplink only in 5 GHz and 6 GHz bands
Minimum data rate is greater than or equal to 1.5 Mbps

Result: no objection

Do you agree to add the following text to the TGbn SFD?

In ELR PPDU, STA boosts L-STF and L-LTF by 3 dB

For UL, non-AP STA corrects CFO before transmission
Note: Non-AP STA pre-correction CFO requirement for residual CFO is TBD

Result: 51 Y/ 6 N/ 23 Abs

Thank you.

Best regards,
