Added a resolution for CID 5283 in the table.

CID 5283

5283 / Fischer, Matthew / 204.11 / 11.5.1.3 / I thought that we had parallel language describing when exactly an HT-immediate BA agreement has been established, but I cannot find such language. / Add language, similar to what is found in 11.15.1.3, to describe just exactly what has to happen in order to establish an HT-immediate BA agreement. / Counter – accept in principle – editor shall execute instructions provided in document 11-07/2746r1 under the heading CID 5283.

11.5.1.3 Procedure common to both originator and recipient

TGn Editor: Change the text of the first paragraph of subclause “11.5.1.3 Procedure common to both originator and recipient” on page 204 at about line 11 of TGn Draft D3.0, as follows, noting that a new paragraph is also added:

The successful establishment of a Block Ack agreement with the Block Ack Policy subfield set to 0 between HT STAs whose last transmitted value for the HT-Delayed Block Ack subfield in their HT Capabilities elements was 1 is defined to be an HT-delayed Block Ack agreement. If either of the two STAs' last transmitted value for the HT Delayed Block Ack subfield of its HT Capabilities element was 0, or if either of the two STAs is a non-HT STA, then a successfully established Block Ack agreement with the Block Ack Policy subfield set to 0 between those two STAs is a Delayed Block Ack agreement.A successfully established Block Ack agreement with the Block Ack Policy subfield set to 0 between two STAs, where either of the two STAs' last transmitted value for the HT Delayed Block Ack subfield of its HT Capabilities element was 0, or where one or both of the two STAs is a non-HT STA, is a Delayed Block Ack agreement.

A successfully established Block Ack agreement with the Block Ack Policy subfield set to 1 between two STAs, where one or both of the STAs is a non-HT STA, is an Immediate Block Ack agreement. A successfully established Block Ack agreement with the Block Ack Policy subfield set to 1 between two HT-STAs is an HT-Immediate Block Ack agreement
