Proposed Resolution of D0 Comment S10-644 Kiran Bynam <author>, <company>
D0 Comment S10-644 • Comment : When amending communication standards one of the issues often encountered is the lack of unassigned fields for future use. • Resolution: Insert at least two unassigned bits in thePHY header in Figure 108. Suggested position: starting at position 15 • Location: Page 178 <author>, <company>
Length Bit 0 Bit 15 R0 R0 R1 R1 R2 R2 R H0 H1 L0 L0 L1 L1 L2 L2 L3 L3 L4 L5 L4 L5 L6 Sub-Header 1 Data Rates Pulse Shape L7 L6 R L7 P0 BM P1 SS Length replication Bit 16 Bit 31 Sub-Header 2 Data Rates HARQ Bits Burst Mode, Scrambler seed Proposed Resolution(s) • Have a header broken into two parts • Increased reliability of most significant bits • More reserved bits for future usage <author>, <company>
Cont’d Sub-Header1 (15 bits) CRC (4 bits) BCH parity Bits (12 bits) Sub-Header2 (15 bits) CRC (4 bit CRC) BCH parity Bits(12 bits) PHY Header for UWB BAN • Advantages • Replication of important data in both the headers • Less important data in one of the headers • Reliability of data important for data decoding improves with square law
