[STDS-802-11-TGBF] 答复: Motion request

Hi Tony,

 

I would appreciate if you could run the motion below in a future meeting as appropriate. Thanks.

The reference document is 11-21/1914r0. 

 

l  Motion text

Move to add the following to the TGbf SFD:

?      Monostatic radar and multiple monostatic radars with coordination are two of the sensing modes for 60GHz WLAN sensing.

?      The detailed information of the multiple monostatic radars coordination is TBD.

 

 

Best wishes,

Rui Du

Hi Tony,

 

I received an offline comment and would like to update the motion text as follows.

 

Move to add the following to the TGbf SFD:

?        11bf shall define a non-Trigger based (non-TB) sensing measurement instance as follows:

•        One non-AP STA is the sensing initiator and one AP is the sensing responder.

•        Once the non-AP STA obtains a TXOP, it shall initiates a non-TB sensing measurement instance by transmitting an NDPA frame to the AP followed by an Initiator-to-Responder (I2R) NDP SIFS after. SIFS after the I2R NDP, the AP shall transmit a Responder-to-Initiator (R2I) NDP to the non-AP STA.

•        If the non-AP STA is only the sensing transmitter, then the NDPA frame should configure the R2I NDP to be transmitted with minimum possible length with one LTF symbol.

•        If the non-AP STA is only the sensing receiver, then the NDPA frame should configure the I2R NDP to be transmitted with minimum possible length with one LTF symbol.

•        The details of the NDPA frame are TBD.

 

The comment is that the current text may confuse people because it sounds like whenever a non-AP STA gets a TXOP, it must always initiate a non-TB sensing measurement instance, which is surely not what I am trying to propose. The modified text will avoid such confusion and make it more clear.

 

Best,

Cheng

Move to add the following to the TGbf SFD:

 

A sensing by proxy (SBP) procedure is defined in which:

  • An “SBP request” consists of a non-AP STA sending an SBP Request frame to an SBP-capable AP STA.
    • An STA that sends an SBP Request frame to invoke SBP (and, as a result, WLAN sensing) is denoted by “SBP requesting STA”.
    • The format and contents of the SBP Request frame are TBD.
  • An AP STA that receives an SBP request shall send to the SBP requesting STA an SBP Response frame to accept or reject the request.
    • The format and contents of the SBP Response frame are TBD.
  • An AP STA that accepts an SBP request shall initiate WLAN sensing procedure(s) with one or more non-AP STA(s) using operational parameters derived from those indicated within the SBP Request frame.
  • Measurement results obtained in WLAN sensing procedure(s) resultant from an SBP request shall be reported to the SBP requesting STA.
