  2. Revised PHY/MAC proposal for TG3c H. Nakase, S. Fukuyo, Y. Nagai and A. Fujimura Tohoku University Mitsubishi Electric Corp. H. Nakase, Tohoku Univ./ Y. Nagai, Mitsubishi Electric

  3. Next Step Towards Down Selection • Tohoku University and Mitsubishi Electric have agreed to create a joint submission with COMPA. • Continue to make a Joint Submission during the Meeting in San Francisco H. Nakase, Tohoku Univ./ Y. Nagai, Mitsubishi Electric

  4. Differences of the proposal against CoMPA • PHY • Channelization bandwidth based on 2184MHz • Binding several channels for throughput of more than 2Gbit/sec • MAC • Detail procedure of automatic device discovery using the dedicated control channel H. Nakase, Tohoku Univ./ Y. Nagai, Mitsubishi Electric

  5. Basic-rate (0.5GHz) channel plan Ch #C8 Ch #B1 Ch #C1 Ch #B2 Ch #C2 Ch #C9 Ch #C3 Ch #C10 Ch #B3 Ch #C4 Ch #C11 Ch #B4 Ch #C5 Ch #C12 Ch #B5 Ch #C13 Ch #B6 Ch #C6 Ch #C7 Ch #C14 Ch #B7 546 MHz 416 MHz 116 MHz 148 MHz Ch #C15 1 2 3 4 57 58 59 60 61 62 63 64 65 66 fGHz • Channel separation: 546MHz • Quarter Nyquist BW of that of full-rate channelization H. Nakase, Tohoku Univ./ Y. Nagai, Mitsubishi Electric

  6. Double-rate (1GHz) channel plan 1092 MHz 832 MHz 116 MHz 148 MHz Ch #B1 Ch #B2 Ch #B3 Ch #B4 Ch #B5 Ch #B6 Ch #B7 1 2 3 4 57 58 59 60 61 62 63 64 65 66 fGHz • Channel separation: 1092 MHz • Same XTAL support and PLL architecture as full-rate channelization • Half Nyquist BW of that of full-rate channelization • Lower / upper guard bands: 694 / 846 MHz (US); 878 / 662 MHz (Japan) H. Nakase, Tohoku Univ./ Y. Nagai, Mitsubishi Electric

  7. Full-rate (2GHz) channel plan 2184 MHz 1664 MHz 116 MHz 148 MHz 1 2 3 4 57 58 59 60 61 62 63 64 65 66 fGHz • Support Cell phone XTAL: 13 MHz& Other High frequency XTALs: 30.333, 45.5MHz, … • Balanced margins to 57/66 GHz & Good roll-off factor • Supports Multiple PLL Architectures with the Cell phone XTAL • Dual PLL: High frequency PLL that generates carrier frequencies • Low frequency PLL that generates ADC/DAC & ASIC frequencies H. Nakase, Tohoku Univ./ Y. Nagai, Mitsubishi Electric

  8. Binding several channels for throughput f1 f2 f3 f4 Example : Block diagram of transmitter 2Gbit/sec for DEV Directional antenna Mod Mod S/P Convert Data Mod Mod Channel binding based on 250Msymbol/sec single carrier modulation Reduction of symbol rate for commercially available ADC/DAC H. Nakase, Tohoku Univ./ Y. Nagai, Mitsubishi Electric

  9. MAC Protocol Supplementsfor 802.15.3c H. Nakase, Tohoku Univ./ Y. Nagai, Mitsubishi Electric

  10. Automatic Device Discovery (ADD) • To achieve higher data transmission, supporting directional communication needed in TG3c alternate PHY on 60GHz. • To reduce overhead of automatic device discovery (ADD), supporting omini antenna also needed for MAC design in PNC. • Proposed ADD has following features • Omni antenna for control CH (Low Rate PHY) • Device Discovery, Beaconing, etc • Directional antenna for transmission CH (High Rate PHY) • Data transmission omni Low Rate Com. RF PNC DEV sector sector RF SW SW RF High Rate Com. H. Nakase, Tohoku Univ./ Y. Nagai, Mitsubishi Electric

  11. Example of procedure for Usage model #1 PNC DEV power on cont ch start searching PNC ID, free slot beacon (omni) detect (directional) beacon period selected slot response with request at a random slot DD request (omni) DEV ID, data rate start searching sync burst (directional) Continue to transmission until receiving confirmation DD period detect (directional) confirmation (directional) confirmation ack (directional) ch allocation, modulation data ch data H.
