TG3 MAC Subcommittee Report Novemember, 2000 TG3 MAC Subcommittee Report Allen Heberling, Eastman Kodak

MAC Subcommittee’s Merged MAC Meeting November, 2000 doc.: IEEE 802.15-00383r0 Novemember, 2000 MAC Subcommittee’s Merged MAC Meeting Who: Alfvin, Ghori, Gubbi, Heberling, Kinney, Kubler, McCorkle, Meng-Ho, Parks, Rios, Roberts, Schrader, Siep, Shvodian, Stevenson, Welborn Where: J. McCorkle’s Suite Why: To provide a venue for mutual discussion regarding differences/similarities of the Parks and Kinney MAC proposals. Allen Heberling, Eastman Kodak Allen Heberling, Eastman Kodak, Co.

Novemember, 2000 Discussion G. Parks, R. Gubbi and A. Ghori described in detail the operation of their MAC protocol using SC-TDMA P.Kinney and J. Kubler described in detail their MAC proposal’s need for a Contention Access Period immediately following a beacon. Allen Heberling, Eastman Kodak

Park’s MAC Protocol Network Frame Format Novemember, 2000 Park’s MAC Protocol Network Frame Format reQuest Slot PHY frame body PHY frame One PHY frame PHY Header Network Frame One Network Frame Tx Slot for device-0 (master) Tx Slot for device-2 MAC Packet Body PHY frame body (MAC packet) MAC Header FEC, CRC Tx Slot for device-3 Tx Slot for device-n Beacon Slot Cycle TDMA Interval Allen Heberling, Eastman Kodak

Kinney’s MAC Protocol Superframe Novemember, 2000 Kinney’s MAC Protocol Superframe Asynchronous slots Isochronous slots Contention Access Period Beacon Contention Free Period Maintain station synchronization coordinate sleep cycles FH coordination (if necessary) Asynchronous slot/cycle assignments Isochronous slot/cycle assignments Allen Heberling, Eastman Kodak

MAC Protocol Superframe: Contention Access Period Novemember, 2000 MAC Protocol Superframe: Contention Access Period Contention Access Period Contention Free Period Beacon Asynchronous slots Isochronous slots All control messages such as: attachment requests authentication responses slot cycle requests In addition short data frames could be sent in this period Allen Heberling, Eastman Kodak

Novemember, 2000 Resolution G. Parks asked if P. Kinney/J.Kubler would be comfortable if the ReQuest Slot were moved from the end of SC-TDMA sequence to immediately follow the Beacon as per the Kinney MAC proposal. P. Kinney/J. Kubler acknowledged they would. Consequently, ... Allen Heberling, Eastman Kodak

Novemember, 2000 Consensus The MAC subcommittee has agreed on a baseline combination of the Parks and Kinney MAC proposals. Allen Heberling, Eastman Kodak

Consensus continued... The consensus approach is to use: Novemember, 2000 Consensus continued... The consensus approach is to use: the Heberling/Schrader Slot Cycle-TDMA algorithm(currently included in both the Park and Kinney MAC proposals) with the Kinney contention access period slot allocation immediately following the beacon and the Parks multi-media QoS policies. Allen Heberling, Eastman Kodak

Novemember, 2000 Recommendation: TG3 resume its confirmation (75%) vote on the now merged Kinney/Parks MAC proposal …aka Kinney/Parks/Heberling/Davis/Kubler/ Skellern/Gubbi/Schrader/Rios MAC Allen Heberling, Eastman Kodak
