Re: [STDS-802-11-TGBP] November F2F SPs

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 waveformdownlink 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: 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 for bistatic backscatteringexcitation 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 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 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 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.

 

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.
