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

 

Hi Alfred,

 

Could you please add the following motions to 11bn PHY motion list :

 

•       Motion1 : Move to include following text to the 11bn SFD (DCN#11-24/1485r2)

•       The U-SIG field in ELR PPDU consists of 2 OFDM symbols and includes the same version independent fields defined in the U-SIG field of EHT PPDU

•       The details for the version dependent fields are TBD.

•       Results: No objection

 

•       Motion2 : Move to include following text to the 11bn SFD (DCN#11-24/1486r1)

•       The BW of ELR PPDU is 20MHz and one Spatial stream is used for ELR transmission. 

•       Results: No objection

 

•       Motion3 : Move to include following text to the 11bn SFD (DCN#11-24/1486r1)

•       In the ELR transmission, a repeating of 52-tone RRU is used in 20MHz.

•       The same data is repeated in four 52-tone RRUs in 20 MHz.

•       The subcarrier allocation of 52-tone RRU equals the 52-tone RU defined in 11be.

•       Results: No objection

 

Best regards,

Dongguk.

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
