doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> <month year> 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> <author>, <company>

Proposed Resolution(s) <month year> doc.: IEEE 802.15-<doc#> <month year> Proposed Resolution(s) Have a header broken into two parts Increased reliability of most significant bits More reserved bits for future usage R0 R1 R2 R L0 L1 L2 L3 L4 L5 L6 L7 P0 P1 Pulse Shape Length Data Rates H0 H1 BM SS Burst Mode, Scrambler seed Length replication Bit 0 Bit 15 Bit 16 Bit 31 Sub-Header 1 Sub-Header 2 HARQ Bits <author>, <company> <author>, <company>

Cont’d Advantages Replication of important data in both the headers 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
