Re: [STDS-802-11-TGBP] Reminding of coming TGbp TC on Mar 25 (Wed)

Hi Bo,

 

Thanks for the agenda, and apologies for late request. Please help to replace SP 1, 2, 3, 4, 5 in SFD MAC SP SET #25 (Rojan) as below. SP4 & SP5 are combined as SP4.

 

SFD MAC SP SET #25 (Rojan):

SP1: Do you agree to add the following to the 11bp SFD:

  • Upon receiving an AMP Trigger frame that indicates time‑slot‑based random access and includes ACW and the number of slots N, a non‑AP AMP STA performs the following:
    • Randomly select the AMP Backoff Counter (ABOC) in the range [0, ACW].
    • If the selected ABOC is less than N, transmit an uplink AMP PPDU in slot ABOC+1. Otherwise, the STA does not transmit in response to the AMP Trigger frame.
    • How a non-AP AMP STA selects ABOC in the case of retransmission is TBD.

 [Reference: 25/2035r0, 25/1246r0, 25/1240r0, 25/1242r0, 26/0121r0, 26/0592r0, 11-25/1865]

SP2: Do you agree to add the following to the11bp SFD:

  • For bi-static backscatter communication, the AMP frame that solicits uplink response (e.g., AMP Trigger frame, or AMP SP Advert frame) shall indicate the direction of the frequency shifting (higher or lower, relative to the excitation signal) to be used by a non-AP AMP STA to transmit the uplink AMP response.

[Reference: 26/0124r0]

SP3: Do you agree to amend motion MM-7 in the 11bp SFD as:

MM-7:

  • An 802.11bp client may uses the receive time of the end of the last symbol of the DL AMP PPDU carrying the AMP Trigger frame, which solicits UL AMP PPDUs from the client, to determine the timing for transmitting UL AMP PPDUs in the same TXOP
  • The definition of receive time is TBD.

[Reference: 26/593r1, 11-25/353]

SP4: Do you agree to add the following to the 11bp SFD:

  • During a multi-slot uplink access TXOP for Active Tx non-AP AMP STAs, the AMP AP shall transmit an AMP Ack frame to indicate the start of the second or subsequent time-slot.
  • A non AP AMP STA eligible to transmit in a time slot other than the first slot, transmits its UL AMP PPDU within the applicable IFS from the end of the DL AMP PPDU carrying the AMP Ack frame.

[Reference: 26/593r1, 11-24/2113]

 

Best Regards,

Rojan Chitrakar

Hello, all, 

 

A tentative agenda for the coming TGbp teleconferences is uploaded to the server. 

 

To Solomon and Sam, your SP update requests are received and will be implemented before the SPs.

 

Best Regards,

Bo

Hello, all, 

 

This email serves as a reminder of the coming TGbp TC on Mar 25 (Wednesday, instead of Tuesday).

 

In the TC on Mar 25, we will first review the editor's report, then go on the pending SFD SPs as listed in Mar plenary meeting agenda 11-26/0276r6. 

 

There're still 3 MAC contributions in current submission list (11-26/0174 from Alfred, 11-26/0627 and 11-26/0628 from Liwen). Please the owners of these submissions confirm whether you're available to present these contributions in the coming TC or any TC slot you prefer, so that I can setup the agenda for these submissions.

 

If you have any new submissions or pending SPs to update, please send your requests to the reflector 24 hous before the intended TC. Thanks!

 

Best Regards,

Bo
