  5. Scalable PHY Architecture Mandatory Hooks for Optional Robustness Enhancement Closed Loop TX BF Open Loop SDM Robustness Enhancement LDPC Conv. Coding Rate Feedback Throughput Enhancement 2 Spatial Streams 4 Spatial Streams Regulatory Constraints Low Cost & Robust 20 MHz 40 MHz 6 to 140 Mbps 6 to630 Mbps 6 to243 Mbps Syed Aon Mujtaba, Agere Systems, et. al.

  6. Benefits of TGn Sync Preamble • Simple baseline channel estimation algorithm • No need for complex interpolation/smoothing algorithms • 100% backward compatible • Low fluctuation of average receive power • low cost ADC & high precision AGC • Flexible per spatial stream training • SDM • Spatial Spreading (Walsh + CDD) for Nss < Ntx • TX Beam-forming • STBC (if TGn chooses to add that as an option) • Extensibility • upto 4 spatial streams, across 40MHz, with TX beamforming • Future PHYs will be backwards compatible to 11a/g/n Syed Aon Mujtaba, Agere Systems, et. al.

  7. 2x2-40 MHz 4x4-20 MHz 2x3-20 MHz w/ short GI 2x2-20 MHz w/ short GI Why 40MHz is Mandatory? • 2x2 – 40 MHz • Only 2 RF chains => Cost effective & low power • Lower SNR at same throughput => Enhanced robustness 260 240 220 200 Sweet spot for 100Mbps top-of-MAC 180 160 140 Over the Air Throughput (Mbps) 120 100 80 Basic MIMO MCS set No impairments 1000 byte packets TGn channel model B 60 40 20 0 0 5 10 15 20 25 30 35 SNR (dB) Syed Aon Mujtaba, Agere Systems, et. al.

  8. Why introduce TX Beamforming? 1000 byte packets No impairment 20MHz, channel D 4 TX-antenna AP  2 RX-antenna client ~10 dB gain of 4x2-ABF over 2x2-SDM => cost effective client Syed Aon Mujtaba, Agere Systems, et. al.

  9. Scalable MAC Architecture • LEGACY INTEROP. • Long NAV • Pairwise Spoofing • Single-Ended Spoofing Robust & Scalable MAC Architecture • ADDITIONAL EFFICIENCY • Header Compression • Multi-Receiver Aggregation • Bi-Directional Data Flow • BA Enhancements • BASELINE MAC • Robust Aggregation • QoS Support (802.11e) • Rx assisted link adapt. • CHANNEL MANAGEMENT • 20/40 MHz Modes Syed Aon Mujtaba, Agere Systems, et. al.

  10. MAC Summary of TGn Sync Proposal • Mandatory Features: • MAC level frame aggregation • RX assisted link adaptation • QoS support (802.11e) • MAC header compression • Block ACK compression • Legacy compatible protection • 20/40 MHz channel management • Optional Features: • Bi-directional data flow • MIMO RX Power management Syed Aon Mujtaba, Agere Systems, et. al.

  11. RX Assisted Link Adaptation Protocol • Support for PHY closed-loop modes with on-the-air signalling • Request for training and feedback are carried in control frames • Rate feedback supported • Transmit beamforming training supported • sounding packet • calibration exchange • Timing of response is not constrained permitting a wide range of implementation options Syed Aon Mujtaba, Agere Systems, et. al.

  12. Thank You! • We would like to thank all for their feedback, which has strengthed our proposal • We are a technology forum, and are looking forward to merger talks with other proposals • For more info, please visit www.tgnsync.org Syed Aon Mujtaba, Agere Systems, et. al.

  13. Key Features • Scalable PHY & MAC Architecture • 20 and 40 MHz channels – fully interoperable • Data rate scalable to 630 Mbps • Legacy interoperability – all modes • Robust preamble • Transmit beamforming • Robust frame aggregation • Bi-directional data flow • Receiver assisted fast link adaptation Syed Aon Mujtaba, Agere Systems, et. al.
