TG3 Merged MAC Proposal Executive Summary

Doc: 00401r0

During the November, 2000 Session of the 802.15.3, TG3 voting members unanimously approved the high rate wireless personal area network (HR WPAN) media access control (MAC) proposal based upon the merger of the Kinney, Parks/Gubbi/Davis, and Heberling MAC proposals.

The key components of the Kinney MAC protocol proposal (documents 205r2, 218r1) are that it:

provides proven support for mobile wireless personal area networks (WPAN).
enables WPANs to interact with wired infrastructure access points.
enables a WPAN to temporarily separate into two subnets and then recombine via an efficient reauthentication and reassociation procedure.
provides proven protocol support for efficient power management policies

The key components of the Parks/Gubbi/Davis MAC protocol proposal (documents 208r3, 209r3) are that it supports:

redundant master coordinators.
direct peer to peer communications within a multi-node piconet
repeater service.
virtual data streams(Asynchronous and Isochronous).
negotiating QoS paramenters in a WPAN environment.
dynamic channel selection and/or migration.
adaptive FEC and selective retransmission ARQs.

The key components of the Heberling MAC protocol proposal (document 212r1) are that it provides:

an efficient Slot Cycle TDMA algorithm for accessing the RF medium.
support for Isochronous and Asynchronous data streams.
bounded latencies.
support for negotiating channel bandwidth allocations.

The goal of the TG3 MAC committee is to integrate by July, 2001 these key MAC components into a unified, draft MAC standard which will address the requirements of a high rate MAC protocol capable of supporting both Isochronous and Asynchronous data exchanges in HR-WPANs.
