[STDS-802-11-TGBP] SFD SP request

[Sam Shi <Sam.Shi@xxxxxxxxxxxxxxxx>]

Hi Bo,

Please add following SFD SP to the agenda:

Do you agree to add the following text in the TGbp SFD:

• 11bp supports secure one-shot communication between the AMP AP and STAs without requiring a discovery and/or association phase. 
• A DL PPDU with UL access information and parameters for security procedure.
• An UL PPDU with protected UL response.
• A DL Ack acknowledges that the UL PPDU was successfully received and decoded.
• There is no Ack if the PPDU was not received nor decoded.

Note:

• Such one-shot communication still follows the baseline security mechanism in MM-17/Motion #64
• The above does not apply to mono-static backscatter non-AP AMP STAs.

[Reference: 11-26/0605r1]

Also for MAC SP Set #18, please postpone SP #1.

Thanks,

Sam

Hi Bo,

In 11-25/1692r21 slide 80, could you please change my deferred SP to the following? It's better to run it after the first SP of 11-26/582r0 if it is queued.

• SP: Do you agree to add the following to the 802.11bp SFD?
• In the U-SIG field in DL AMP PPDUs, if the AMP Mode indicates bistatic backscatter communication, the U-SIG field includes the following mode dependent contents:
• Uplink channel for bistatic backscatter communication (1 bit)
• Set to 0 to indicate the lower 20MHz channel relative to downlink
• Set to 1 to indicate the upper 20MHz channel relative to downlink
• Bistatic Exciter transmission flag (1 bit)
• Set to 0 to indicate the PPDU is transmitted by an AMP AP
• Set to 1 to indicate the PPDU is transmitted by a bistatic exciter
• Bistatic Exciter Identification (TBD bits)
• Reserved bits (at least 2 bits, 1 Validate, 1 Disregard)

[Reference contributions: 11-26/0091r0, 11-25/2070r2]


Could you please add the following SP to the queue?

• SP: Do you agree to add the following to the 802.11bp SFD:
• In the data field of AMP UL active transmission in 2.4 GHz, 4Mbps data rate only uses 0.125us chip duration, Manchester encoding and OOK modulation
