Hi Bo,

Can you help to add the deferred PHY SFD SP Set #30 to the May SP queue? Add one note from offline discussion.

SP #2: Do you agree to add the following text into the 802.11bp SFD?
• The U-SIG of AMP DL PPDUs for mono-static backscattering is defined as below.
• Note: when AMP Mode bits indicate MS-BST
• Note: “Multi-TXOP” indication is for other AMP APs operating in the same channel to hold the channel access.
[References: 11-26/582r1]

Thanks,

Rui

Hi Bo,

Can you help update SP1 of SP set #24 as follows for Wed discussion?

11bp supports data communication between unassociated AMP AP and STAs consisting of the following frame exchange:

An AMP DL frame with UL access information and possible application data

An AMP UL frame with UL response and possible application data

Note: Whether security is applied to the UL response is TBD.

Thanks,

Sam

Hi all,

There have been some offline discussions on this "one-shot" communication. The idea behind SP #24 is to support "one-shot data" communication such that the 1st frame exchange between an AP and a STA is DL trigger and UL response containing "data". None of the previous SPs explicitly support this very important scenario.

Having said that,

Option 1:

I propose we can capture the SP as follows:

11bp supports data communication between unassociated AMP AP and STAs consisting of the following frame exchange:

An AMP DL frame with UL access information and possible application data

An AMP UL frame with UL response and possible application data

Option 2:

If we do not want to use the wording "unassociated", we may do the following

11bp supports data communication between AMP AP and STAs without previous frame exchange(s):

An AMP DL frame with UL access information and possible application data

An AMP UL frame with UL response and possible application data

Let me know what you think. This is the "best" wording that Amichai and I can think of right now...

Thanks,

Sam

Hi Rojan,

I see your point...

Yes, ANY frame exchange would be triggered by the AP in AMP. Having said that, the behavior of "an AMP AP may initiate a random access uplink procedure without requiring previous frame exchange(s)." is already true...

The real thing I want to capture is "an AMP AP and a STA may support an AMP data frame exchange without previous frame exchange".

What do you think we explicitly spell out "data frame exchange"? Then it can be separated from other uplink procedures, e.g. capability exchange, bonding, etc.

Thanks,

Sam

Hi Sam,

We already have many motions in the SFD for uplink access, how about simplifying the SP as below by referencing terms we already agreed (i.e., random access)?

For active Tx and bistatic backscatter non-AP AMP STAs, an AMP AP may initiate a random access uplink procedure without requiring previous frame exchange(s).

Btw, what does previous frame exchange(s) mean here? Any frame exchange would be triggered by AMP AP anyway, isn’t it?

Best Regards,

Rojan Chitrakar

Hi all,

Based on the discussion on last cc, I revised the SP texts reflecting:

Describe the procedure as a sequential frame exchange, i.e. 1^st frame and 2^nd frame.
The text is also simplified.

SP #1: Do you agree to add the following text into the 11bp SFD?

For active Tx and bistatic backscatter non-AP AMP STAs, an uplink access procedure triggered by an AMP AP may be initiated without requiring previous frame exchange(s).

1st frame: An AMP DL frame with UL access information.
2nd frame: An AMP UL frame with UL response.

Note: Whether security is applied to the UL response is TBD.
Note: Content of the UL response is TBD.

Please let me know your comments, if any.

Thanks,

Sam
