Hi Alfred,

 

Can you please add the following CoEx motions to the ones queued before?

 

  • Define a mechanism so that a non-AP STA as a TXOP holder can indicate in a BSRP as the ICF frame 1) for how long it will be available, if known and/or 2) whether it will be unavailable after a specific point in time and, if known, for how long
    • There are conditions under which such a BSRP can be sent, and those conditions are TBD.

Supporting docs: 11-24/1550, 11-24/1558

 

SP Result: No objection

 

Regards,

Sherief

Hi Alfred,

 

Can you please queue the following motions in MAC?

 

  • 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 (range 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 documents: 24/543, 24/857, 24/1226, 24/1247, 24/1558

 

SP results: 121Y / 9N / 45A

 

  • 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 documents: 24/543, 24/857, 24/1226, 24/1247, 24/1558

 

SP results: 114Y / 17N / 63A

 

  • 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
