Re: [STDS-802-11-TGBP] Agenda for TGbp TC on Aug 4 is updated



Hi Bo,

 

Thank you for the agenda. Anticipating some discussion, I request to swap the presentation order of my PDTs and allow me to present 1519r1 first. TTT members, I have uploaded r1 based on offline feedbacks, kindly take a look.

 

1519r1, PDT AMP Triggering Procedure

 

Bo, also I noted that my SP#4 from SFD MAC SP Set #33 somehow got lost from the PS SPs. Since the SPs are related, I request to split my SP1 in PS MAC SP SET #8 into 2 SPs to accommodate the SP#4 from SFD MAC SP Set #33.

In addition, kindly help to update the SP 1A, 1B, 4 in PS MAC SP SET #89 (Rojan) as below:

 

SP #1A: Do you agree to the following?

       Mono-static Backscatter non-AP AMP STAs shall support AMP frames with length up to 64 Octets. Active Tx and bi-static Backscatter non-AP AMP STAs shall support AMP frames with length up to 128 Octets and may support AMP frames with length up to 256 Octets.

       For mono-static Backscatter non-AP AMP STAs, the length of the Frame Body field, if present, is indicated by a 6-bit Frame Body Length field in the MAC Header field in units of octets.

       For Active Tx and bi-static Backscatter non-AP AMP STAs, the length of the AMP frame is indicated either directly as a 6-bit Length of Data Field in the AMP-SIG field or indirectly as a 6-bit Frame Body Length field in the MAC Header field if the Frame Body field is present in the AMP frame. The unit of the length indication depends on the data rate of the AMP PPDU carrying the AMP frame and is:

    • 1 octet if the data rate is 250 Kbps
    • 2 octets if the data rate is 1 Mbps
    • 4 octets if the data rate is 4 Mbps

 

SP #1B: Do you agree to the following?

       If an AMP frame carries a Frame Body Length field to indicate the length of the Frame Body field carried by the frame, the frame shall carry a checksum computed over the Frame Body Length field.

       The Frame Body Length field is 6 bits long and the checksum is 2 bits long.

 

SP #4: Do you agree to the following?

       During a multi-slot uplink access TXOP for Active Tx non-AP AMP STAs, all the DL AMP PPDUs carrying the AMP Ack frame to indicate the start of uplink slots are transmitted at the same data rate as the DL AMP PPDU carrying the DL AMP frame that solicited the uplink access.

 

All, kindly reach out to me if you have any feedback regarding the SPs.

 

Best Regards,

Rojan Chitrakar
