  4. Contents • Physical layer • Implementation and Feasibility • MAC enhancements • Performance Gadi Shor, Wisair

  5. Contents • Physical layer • Implementation and Feasibility • MAC enhancements • Performance Gadi Shor, Wisair

  6. MAC Enhancements (1) • UWB based WPAN system should support a higher bit rate (e.g. 110Mbps, 200Mbps) • Current MAC Throughput is degraded in high bit rate • Support a bigger packet length • Bigger packets may be needed for high data rate applications • Improve the throughput • For both small and large packet sizes • For retransmission mode • Support Multiband channel assignment • Decide on usable sub bands • Select the time frequency interleaving sequence Gadi Shor, Wisair

  7. MAC Enhancements (2) PHY SAP Data Throughput Calculation Payload Throughput PHY-SAP = N x Payload_bits / [ T_PA_INITIAL+T_SIFS + (N-1) x (T_PA_CONT+T_MIFS) + N x (Payload_bits/R_Pay+T_MACHDR + T_PHYHDR+T_HCS+T_FCS)] Gadi Shor, Wisair

  8. MAC Enhancements (3) IEEE802.15.3 PHY-SAP Data Throughput N= 5 Frames T_PA_INITIAL = 15uSec T_PA_CONT = 15uSec MACHDR=10 Octets PHYHDR=2 Octets HCS=2 Octets FCS = 4 Octets T_SIFS = 10uSec T_MIFS = 2uSec Gadi Shor, Wisair

  9. MAC Enhancements (4) IEEE802.15.3 PHY-SAP Data Throughput in High Bit Rates N= 5 Frames T_PA_INITIAL = 15uSec T_PA_CONT = 15uSec MACHDR=10 Octets PHYHDR=2 Octets HCS=2 Octets FCS = 4 Octets T_SIFS = 10uSec T_MIFS = 2uSec Gadi Shor, Wisair

  10. MAC Enhancements(5) Proposed MAC Performance PHY-SAP Data Throughput in High Bit Rates N= 5 Frames T_PA_INITIAL = 15uSec T_PA_CONT = 15uSec MACHDR=10 Octets PHYHDR=2 Octets HCS=2 Octets FCS = 4 Octets T_SIFS = 10uSec T_MIFS = 2uSec Gadi Shor, Wisair

  11. MAC Enhancements (6) Proposed MAC Frame Structure • Allow larger MAC frame body size (e.g. 4096 Octets • Frame body consists of N Sub-frames • Sub-frame consists of Data block unit and CRC • Data block unit is limited by a maximum number of octets (e.g. 512 octets) Gadi Shor, Wisair

  12. MAC Enhancements (7) • The proposed UWB PHY structure is based on multi-band UWB system • MAC logical channel is mapped to several frequency bands • Some bands might be interfered (useless) by other existing systems (I.e IEEE802.11a – 5GHz) • MAC should be able to drive a BandsQuality Assessment (BQA) that determines whether a specific band is usable or not • The Piconet Coordinator (PNC) should be able to distribute the usable bands to all its associated devices Gadi Shor, Wisair

  13. MAC Enhancements (8) • Provide BQA time slot at the Supper-frame • Useful information is distributed as Information Element (IE) over PNC Beacon • Beacon will transmitted over the whole frequency bands Gadi Shor, Wisair
