Re: [STDS-802-11-TGBP] SP text for tomorrow

[Alice Jialing Li Chen <jialing.li.phd2@xxxxxxxxx>]

Hi Bo,

Please add the following  SP to tomorrow SP list, ideally be run after Amichai's 2 SPs and before Shengquan's 2 SPs:

• Do you agree to add the following to the 11bp SFD:
• In the data field of AMP UL active transmission in 2.4 GHz,
• 250kbps data rate only uses 1us chip duration and rate 1/2 binary convolution code (BCC)
• 1Mbps data rate only uses 0.25us chip duration and the same rate 1/2 BCC
• 4Mbps doesn’t use BCC
• Supporting doc: 11-25/1215r1, 11-25/1552r0

Thanks,

Alice

Hi Bo,

 

  Please add the following two SPs to tomorrow SP list:

 

SP#1:

•        Do you agree to add the following to 802.11bp SFD?

–        The Uplink Sync Field Transmission from a non-Backscatter STA for all data rates shall have a length 48

     [Reference Contribution Doc# 11-25/1552r0]

 

 

SP#2:

•        Do you agree to add the followings to 802.11bp SFD?

o   Length-48 sync sequence for UL non-backscatter transmission is constructed by repeating length-24 base sequence twice, i.e. S₄₈ = [S₂₄ S₂₄]

o   The length-24 base sequence is given as below:

S₂₄=[1,  1,  1,  1,  1,  0,  1,  0,  0,  1,  1,  0,  0,  1,  1,  0,  0,  0,  0,  1,  0,  1,  0,  0]

             [Reference Contribution Doc# 11-25/1552r0]

 

Thanks,

Shengquan

Hello Bo,

 

I have 2 SPs to run for this week meeting. If possible to run early slot on Thursday will be good.

 

SP1:

Do you agree to add into section 4.4.3 of the SFD the following text:

“11bp defines mandatory forward error correcting code (FEC) of coding rate ½ for the data portion of UL active transmission in 2.4 GHz at rates of 0.25,1Mbps and non-coded mode at rate of 4Mbps”

[Reference contributions: 11-25/1002r1]

SP2:

 

Do you agree to add into section 4.4.3 of the SFD the following text:

“11bp defines forward error correcting code (FEC) for the data portion of UL active transmission in 2.4 GHz based on the code as defined in 17.3.5.6 in 80211-2020”

[Reference contributions: 11-25/1002r1]

Thank you!
