Re: [STDS-802-11-TGBP] PDT: Energizer Control

Hi Yingqiao,

 

Yes, there have been several edits before the current revision. As per the motion, the AMP Energizer as per motion AM-3, is capable of transmitting WPT and/or excitation, and as you have referenced, the AMP Energizer shares this capability with the AMP AP.

But part of the discussion you may have missed, is the group has not converged on how the excitation signal is sent by an AMP Energizer (that is not co-located with the AMP AP). That is why, till the group converges on this understanding, Fig. 9-x2 has a TBD field as a placeholder for this capability of Energizer function (i.e. WPT/Excitation).

Note, this is the same reason why Excitation functionality is removed from AMP Energizer in other PDTs in the D0.1 spec. My understanding is when consensus is reached, these TBDs shall be clarified.

 

Kind Regards

Ian

Hi Ian,

 

Thanks for your updating. Perhaps because I missed some offline discussions, I have some questions. I sincerely hope to get some feedback.

 

I am confused about this sentence “ The AMP Energizer shall support WPT waveform transmission.”. IMO, this sentence precludes AMP energizers that only supports 2.4G excitation waveform transmission which may be inconsistent with the passed [Motion #81].

And if it is mandatory, why does the capability of supporting WPT transmission need to be defined?

 

[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 2.4G excitation waveform transmission.
    • Maximum Tx power.
    • Note: The energizer should at least support one of the following transmissions: S1G WPT transmission or 2.4G excitation waveform transmission

 

 

BR，

Hi Sanket, and Yinan,

I have accepted your proposed changes, and uploaded r7 to mentor:

https://mentor.ieee.org/802.11/dcn/25/11-25-1357-07-00bp-pdt-wpt-energizer-control.docx

 

Hi Bo,

Please update the PDT SP as:

 

Do you agree to incorporate the proposed draft text in document 11-25/1357r7 into the next version of the 11bp draft?

 

Thanks and Regards

Ian
