Hi Xiandong,

According draft 0.01 (refer to Clause 11.21.18.1 Overview, especially Figure 11-41―Example of a WLAN sensing procedure), AP can initiate TB measurement setup (this setup will keep active before termination), then STA can also initiate non-TB measurement setup before the TB measurement setup is terminated.

That is to say, both TB and non-TB cases are active at the same time period.

Therefore, AP or non-AP STA can initiate measurement setup termination for TB case and/or non-TB case.

Best regards,

Pei

Hi Pei,

I don’t understand what does the sentence “Since both TB and non-TB cases may overlapping in time” mean, it means the both cases could be occurred simultaneously for the same initiator and responder?

Best regards

Xiandong

Hi Solomon,

Thanks for your clarifications and comments.

Yes, the case is that the same non-AP STA participates in both TB and non-TB sensing with the same AP.

I think your idea is to use two termination frames, one to terminate some measurement setups in TB case and the other to terminate some measurement setups in non-TB case.

Since both TB and non-TB cases may overlapping in time, why we just use one termination frame to terminate measurement setups in both TB and non-TB cases?

Best regards,

Pei

Hi Pei,

The presentation introduces overlapping of the MS IDs based on the assumption that both the AP and non-AP allocate the MS ID value. The assumption is wrong for TB sensing. It may be relevant when observing both TB and non-TB sensing. So, the case is that the same non-AP STA participates in both TB and non-TB sensing with the same AP. So, one solution can be to indicate in the termination frame what it is TB or non-TB and not to mixt the TB and non-TB in the same termination frame. No need for any TX/RX fields.

Best regards,

Solomon Trainin

Hi all,

I presented this contribution today. Let me explain a little bit:

1. Both AP and STA can maintain multiple measurement setups. It is not efficient if we limit one termination frame from only terminating one measurement setup (ID).

2. When we terminate multiple measurement setups by one termination frame, we need to indicate who set the measurement setup ID(s).

3. The method of indicating who set the measurement setup ID(s) is that we use two list (Tx List and Rx List), the “Tx” and “Rx” is the “Transmitter” and ”Receiver” of the termination frame.

4. Why we don’t use “Initiator List” and “Responder List”? Because both AP and non-AP STA can act as Initiator. “Initiator List” and “Responder List” maybe misleading to the receiver of the termination frame.

I hope my explanations can address some of your concerns. Your comments and suggestions are welcome.

Best regards,

Pei Zhou
