Re: [STDS-802-11-TGBF] 11-22-1830-02-00bf Resolution of DMG CID 351 356



Hi Solomon,

 

I guess I didn’t make my points clear.  Let me clarify the question:

“The Allocation ID subfield shall be unique per the DMG Measurement setup ID” could be interpreted as two distinct meanings:

  1. For one responder, different Allocation ID shall be assigned to different MSs. For different responders, if they participate in the same MS, they shall be assigned with the same allocation ID; if they participate in different MSs, the allocation ID shall be different.
  2. For one responder, different Allocation ID shall be assigned to different MSs. For different responders, no matter they participate in the same or different MS, the allocation ID could be same or different. 

 

BR,

Chaoming

Hi Chaoming,

Thank you for the comment.

Please note that “The Allocation ID subfield, when set to a nonzero value, identifies an airtime allocation from Source AID to Destination AID”.

So, the rule “The Allocation ID subfield shall be unique per the DMG Measurement setup ID” is to use the airtime for one particular DMG Measurement setup ID.

Even when different Source AID and Destination AID use the allocated airtime, it is still limited for one specific DMG Measurement setup ID.

Hi Solomon,

 

Thanks for the clarification! I understand your intention now. But still has a few comments for wording:

The Allocation ID subfield shall be unique per the DMG Measurement setup ID” sounds confusing, since multiple STAs may receive same DMG MS ID. E.g., Could Allocation ID 1 be used for both STA 2 and 4 participating DMG MS ID 3? Or your text is indeed enforcing the use of same Allocation ID for multiple STAs participating in the same DMG MS?

Note that in baseline we have “Except for CBAP allocations with broadcast Source AID and broadcast Destination AID, the tuple (Source AID, Destination AID, Allocation ID) uniquely identifies the allocation”, which means Allocation ID singly does not identify an allocation.

 

BR,

Chaoming

Hello Chaoming,

You noted that the SP allocation shall contain the DMG Measurement setup ID.

There is no such need. Destination AID indicates the responder participating in the SP. From the extended schedule element, the responder knows that it participates in the SP at the specified time, and the instance information is delivered in the DMG Sensing Request frame, just as it is in the case of CBAP.
