Hi Bo,

Please help revise my SP text (SP1 in SP Set #10). For reference, I've attached the .pptx slide so that it keeps the strikethrough formatting.

SP #1: Do you agree to update the 11bp SFD as below ? [Nov 13, AM1, 2025; Nov f2f]

[Motion #34]

•IEEE 802.11bp defines an AMP Energizer that contains an Energizing Function, which is capable of transmitting WPT waveform and/or ~~excitation waveform~~downlink AMP PPDU subtype 2 with AMP-SIG for bistatic backscattering ~~for backscattering operation~~. Additionally, the AMP Energizer may contain or be co-located (which one is TBD) with an IEEE 802.11 non-AMP non-AP STA.

• Note: WPT waveform is transmitted over sub1-GHz. Depending on whether the backscattering operation happens in sub1-GHz or 2.4GHz, accordingly the downlink AMP PPDU subtype 2 with AMP-SIG for bistatic backscattering~~excitation waveform~~ will be transmitted in the same band.

[Motion #81]

• IEEE 802.11bp defines at least the following capability parameters to be reported by the energizer to the AMP AP.

• Whether or not support S1G WPT transmission

• If supported, frequency related parameters for WPT. The frequency related parameters may include central frequency information, bandwidth information, etc.

• Whether or not support transmission of AMP DL PPDU subtype 2 with AMP-SIG for bistatic backscattering 2.4G ~~excitation waveform transmission~~.

• Maximum Tx power.

• Note: The energizer should at least support one of the following transmissions: S1G WPT transmission or AMP DL PPDU subtype 2 with AMP-SIG for bistatic backscattering in 2.4G ~~excitation waveform transmission~~.

[Motion #84]

• Control information that may be sent from the AMP AP to the AMP Energizer relating to the ~~excitation signal~~ transmission of AMP DL PPDU subtype 2 with AMP-SIG for bistatic backscattering includes one or more of the following: Start Time, Duration, Transmit Power and frequency related parameters.

• The frequency related parameters may include central frequency information, etc.

Hi Rojan,

Thanks for your feedback. Yes, I will defer SP2.

Hi Nelson,

It is a bit early to run SP#2 in my opinion. There can be other alternative solution(s); for example, one was presented in 25/2057r0. Can we defer it this time?

Best Regards,

Rojan Chitrakar

Hi Bo,

Please help to add the the following two SPs to the PDT queue (PHY):

SP #1

Do you agree to amend the following SFD motions according to the redline text shown below?

[Motion #34]

•      IEEE 802.11bp defines an AMP Energizer that contains an Energizing Function, which is capable of transmitting WPT waveform and/or ~~excitation waveform~~downlink AMP PPDU subtype 2 for bistatic backscattering ~~for backscattering operation~~. Additionally, the AMP Energizer may contain or be co-located (which one is TBD) with an IEEE 802.11 non-AMP non-AP STA.

Note: AMP DL PPDU subtype 2 is defined in Motion #88.

SP #2

Do you agree to add the following to the TGbp SFD?

·         When an AMP Energizer transmits an AMP DL PPDU subtype 2 for bistatic backscattering, its data should be limited to the following content,

o   STA ID

o   Session token

o   Other information TBD.
