Hi Bo,
Please find the updated text for some of my Straw Polls below
in red. Also I have indicated straw polls to be deferred.
Thanks and Regards
Ian

Hi Bo,
Please find the straw polls I plan to run tomorrow. All are intended for SFD motion.
- Do you agree to add the following text to TGbp SFD?
- IEEE 802.11bp allows a non-AP AMP STA to report the transmission time it can sustain. Furthermore, a one-time report of
a fixed multiplicative factor of the transmission time, may be reported to indicate the time that the non-AP AMP STA can sustain other modes of operation. How the non-AP AMP STA may
report these times is TBD.
- Note:
- Other modes of operation may include reception, channel sensing, and idle.
- Idle mode refers to a mode of operation with no RF activity, i.e. the non-AP AMP STA cannot transmit or receive any frames
in this mode.
- Other modes of operation may include reception, channel sensing, and idle.

SP2
- Do you agree to add the following text to TGbp SFD?
-
IEEE 802.11bp defines an AMP SP frame as one type of AMP Frame to carry AMP Service Period information.
[Reference: 11-25/0039r0, 11-25/0285r1, 11-25/0787r0, 11-25/1244r0]
SP3
- Do you agree to add the following text to TGbp SFD?
- The AMP SP Frame carries the SP ID, SP Start Time, SP Interval, and the SP Minimum Wake Duration. The SP ID serves to
uniquely identify the AMP Service Period.
[Reference: 11-25/0039r0, 11-25/0285r1, 11-25/0787r0, 11-25/1244r0]
- Do you agree to add the following text to TGbp SFD?
-
IEEE 802.11bp defines an AMP SP Advert frame as a variant of AMP SP Frame to carry timing synchronization information
that is equivalent to the time remaining to the start of the SP. The timing synchronization information may be expressed as a function of the SP Advert Interval, and SP Advert count, or as partial TSF bits of the AMP AP’s TSF.
-
Note:
-
The SP Advert Interval is the periodicity of the AMP SP Advert frame.
-
The SP Advert Count is a decremental counter, that is counted down in each subsequent AMP SP Advert frame.
-
The SP Advert Interval is the periodicity of the AMP SP Advert frame.

SP5 (will defer for now, based on feedback)
Do you agree to add the following text to TGbp SFD?
-
AMP Service Period allows a Backscatter non-AP AMP STA to enter doze state after a minimum wake up time since the start of the AMP Service Period, if the Backscatter non-AP AMP STA does not receive any AMP DL PPDU from the AMP AP, and can support duty-cycle operation.
[Reference: 11-25/0039r0, 11-25/0285r1, 11-25/0787r0, 11-25/1244r0]
SP6 (will defer for now, based on feedback)
Do you agree to add the following text to TGbp SFD?
-
IEEE 802.11bp allows a non-AP AMP STA to report its clock accuracy to the AMP AP.
[Reference: 11-25/0039r0, 11-25/0285r1, 11-25/0787r0, 11-25/1244r0, 11-25/1245r0]
SP7
- Do you agree to add the following text to TGbp SFD?
-
IEEE 802.11bp defines a broadcast
AMP frame to carry non-short AMP TSF in the Frame Body.
-
The other fields carried in the AMP Beacon are TBD.
[Reference: 11-25/0039r0, 11-25/0285r1, 11-25/0787r0, 11-25/1247r0]
SP8
- Do you agree to add the following text to TGbp SFD?
-
The length of the non-short AMP TSF field is 24 bits. The AMP TSF field carries the partial TSF
bits [6:29] of the AMP AP’s TSF.
[Reference: 11-25/0039r0, 11-25/0285r1, 11-25/0787r0, 11-25/1247r0]
SP9 (won’t run this, combined with SP8)
Do you agree to add the following text to TGbp SFD?
-
The AMP AP’s TSF bits [6:29] is carried in the AMP TSF field in the AMP Beacon Frame.
[Reference: 11-25/0039r0, 11-25/0285r1, 11-25/0787r0, 11-25/1247r0]
SP10
- Do you agree to add the following text to TGbp SFD?
-
IEEE 802.11bp defines AWUR frame as one type of AMP frame with the Frame Body including WUR Frame (excluding FCS).
-
Note: AWUR means Ambient Wake-up Radio
