Re: [STDS-802-11-TGBN] CoEx SPs

Hi Sherief,

Please add 11-24/1559 for the supporting list against SP5 mentioned in your email below. I had in fact queued this SP in the last F2F but had not got a chance to present this document which included it.

Regards,
Sindhu

Hi Alfred,

 

Can you please add the following SPs to the MAC queue?

 

Starting numbering from SP5 following the 4 SPs sent earlier.

 

SP5: Do you agree with the following:

  • Unavailability Target Start Time is indicated using 9 bits with a granularity of 64us
  • Unavailability Duration is indicated using 9 bits with a granularity of 64us

Supporting list: [11-24/543, 11-24/857, 11-24/1226, 11-24/1247, 11-24/1558]

SP6: Scheduled periodic power save on AP side is performed in UHR using Broadcast TWT with TWT ID=0 with Responder PM=1 as described in 26.8.3.2 Rules for TWT scheduling AP

Supporting list: [11- 23/1934, 11- 23/1964, 11- 23/2002, 11- 23/2040, 11-23/2078, 11-24/0509, 11-24/1558]

 

Again, should any of the group members have DCNs that match the SPs and are not in the supporting list, please let me know.

 

Regards,

Sherief

Hi Alfred,

 

Would you please add the following SPs to the MAC queue (first two were already queued during September meeting)?

 

SP1: Do you support defining the following fields for unavailability indication in M-STA BA frames:

    • an Unavailability Target Start Time field defined as the TSF time at which the STA becomes unavailable (duration and resolution TBD, expectation is to use a portion of the TSF)
    • an Unavailability Duration field defined as the time during which the STA is unavailable (field may be not present or set to an unknown value)

 Supporting list: [11-24/543, 11-24/857, 11-24/1226, 11-24/1247, 11-24/1558]

 

SP2: Do you support to define a special Feedback Per AID TID Info field (name TBD) that carries control feedback in the M-BA frame?

    • The control feedback (i.e. unavailability indication) is carried instead of the BlockAck Bitmap in that Feedback Per AID TID Info field
    • The Ack Type subfield of the Per AID TID Info field is set to 0 and the TID subfield of the Per AID TID Info field is set to a reserved value
    • The AID11 subfield of this Per AID TID Info field is set to a reserved TBD value if the control feedback is addressed to all STAs or to the AID11 that identifies the intended recipient STA
    • The Starting Sequence Number field of this Per AID TID Info field is reserved

 Supporting list: [11-24/543, 11-24/857, 11-24/1226, 11-24/1247, 11-24/1558]

 

SP3: Define a mechanism (based on management level signaling) that allows a STA to provide an update to its peer STA of specific operational Tx/Rx parameters (which parameters is TBD, focusing generally on local constraints (for example, coexistence constraints))

 Supporting list: [11- 23/1934, 11- 23/1964, 11- 23/2002, 11- 23/2078]

 

SP4: Do you support that the parameter update mechanism based on management level signaling allows a non-AP STA to transition in/out of a limited operation/capability mode

    • A STA in limited operation/capability mode changes one or more of the following TX/RX parameters: Maximum PPDU duration, Maximum MCS, use of LDPC, use of HT-immediate BlockAck, Disabled Subchannel bitmap, etc.
    • Optional/mandatory TBD

 Supporting list: [11- 23/1934, 11- 23/1964, 11- 23/2002, 11- 23/2078]

 

In the meantime, if any of the members have any contributions that align with the SPs above and I missed in the supporting documents lists, then please feel free to reach out to me and share your DCN.

Sherief
