Resolve a number of CIDs on MDA November, 2008 Resolve a number of CIDs on MDA CIDs: 243-250, 312, 313, 320, 398, 531, 588, 590, 592, 612, 620, 621, 623, 624, 626-629, 634, 1040, 1309, 1337, 1483, 1538-1540, 1582, 1583, 1875, 1879- 1882 Normative text: IEEE 802.11-08/1384r0; the excel sheet describing the comment resolution is 11-08/1387r1 Dee Denteneer, Philips

November, 2008 CIDs: 243-250, 312, 313, 320, 398, 531, 588, 590, 612, 620, 621, 623, 624, 626-629, 634, 1483, 1540, 1582, 1583, 1875, 1881, 1882 Many requests for explanation, reference to frame format Clauses, and editorial stuff. 243“The management frames that are used for this behavior are missing and it is difficult to read.” 245: Modify the sentence to be understandable. 247: Clarify. 320: Clarify the protocol and modify the text accordingly. The format of the TX-RX times report field is complex. Simplified format is preferable. 823: The sentence starting from line 29 is not easy to understand. Make the description more "easy to read". Dee Denteneer, Philips

November, 2008 CIDs: 592, 1040, 1309, 1337, 1538, 1539 Simplify format and introduce a reservation field Structure now is: MDAOP: period of time MDAOP Reservation: field to descrcibe one or more MDAOPs, repeated in MESH DTIM MDAOP Reservation Report: A report of MDAOPs Reservations There are three kinds of reports: TX-RX, Broadcast, and Interfering times MDAOP Advertisements: contains a selection of Reservation Reports, along with MDAOP information Dee Denteneer, Philips

November, 2008 CIDs: 1879 “"Either the transmitter or the receiver may initiate a teardown by transmitting“ This highlights a problem with use of the general terms transmitter and receiver. How can a receiver transmit?“ Define and consistently use terms named <protocol> <role>. For example, in TGe there is a TXOP initiator, TGn there is an RD initiator, RD responder and others similar. So in this case the roles would be MDAOP initiator and MDAOP responder.” Rather a lot of changes. Dee Denteneer, Philips
