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

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)]

11. MAC Enhancements (6) Proposed MAC Frame Structure
March 2003
MAC Enhancements (6) Proposed MAC Frame Structure
Allow larger MAC frame body size (e.g 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

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 Bands Quality 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
March 2003
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
