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.

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.

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.

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
