Re: [STDS-802-11-TGBP] TGbp TC on Apr 28

Hi Bo,

In the 4/28 agenda, could we move my PDT 11-26/0781r0 to be after the two technical contributions, in the 1st hour? I want to make sure my contribution 11-26/0821r0 can make it. 11-26/0821r0 is related to Nelson's SP#1 in PHY SP Set #26. I had an offline discussion with Nelson on the recommended waveform sequences for the bistatic backscatter excitation field. After the presentation of 11-26/0821r0, I would like to add the following PHY SP to the queue. Sequence 1 in the SP is the same sequence in Nelson's SP#1. Sequence 2 is proposed in 11-26/0821r0.

•SP: Do you agree to add the following text into the 802.11bp SFD?

–The following OFDM sequences (with 312.5kHz tone spacing) are recommended for the carrier waveform generation for the excitation field in bistatic backscatter communication.

•Sequence 1: Use L1 = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,-1,1,1,-1,-1,1,1,-1,-1,-1, 1,1,-1,-1,-1,1,0,1,-1,-1,-1,1,-1,1,-1,-1,-1,-1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0, 0,0] for tone indices {-32, …, 31}, if the UL channel is in the upper 20MHz relative to the DL channel. Otherwise, use L1([1, end:-1:2]) for tone indices {-32, …, 31}, if the UL channel is in the lower 20MHz relative to the DL channel.

•Sequence 2: Use L2 = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,-1,-1,1,1,-1,-1,-1,-1, 1,1,1,1,1,1,-1,-1,0,1,1,1,1,1,-1,1,-1,1,-1,-1,1,-1,1,-1,1,0,0,0,0,0,0,0,0,0,0,0, 0,0,0,0] for tone indices {-32, …, 31}.

–Note: Following Motion #39, each carrier waveform would consist of the repeated base waveform, multiplied by a pseudo-random phase.

–Note: The use of those OFDM sequences in carrier waveform generation for other AMP fields is TBD.

Hello, all, 

The agenda for the coming TGbp TC on Apr 28 is adjusted based on recently received request and the progress of pending contributions and SPs. 

https://mentor.ieee.org/802.11/dcn/26/11-26-0694-08-00bp-tg-bp-tc-agenda-till-may-2026.pptx

3 pdt proposals and 2 contributions are scheduled for the 1st hour roughly. And the 2nd hour is scheduled for pending SPs. There're only two TCs left before May f2f meeting, and it's planned to complete all pending contributions and SPs before the f2f meeting. To make a better progress, I'd like to encourage the owners of SPs to talk to members who were interested in the topics during the corresponding proposal presentation by emails or offline discussion, and try your best to get some consensus before we conduct the SPs during the TCs.  

Your contribution and collabloration are sincerely appreciated!

Best Regards,

Bo
