  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Resolution for PHY header] Date Submitted: [September, 2009] Source: [Kiran Bynam, Seung Hoon Park, Thenmozhi Arunan, Euntae Won] Company [Samsung Electronics] Address [Bagmane tech park, Bangalore] Voice:[+91-8041819999], FAX: [E-Mail:[kiran.bynam@samsung.com] Re: [Proposed Resolution of D0 Comment S10-644] Abstract: [Resolution for the comments regarding PHY header and its inability to update for future revisions is addresssed.] Purpose: [to modify the PHY header section accordingly] Notice: This document has been prepared to assist the IEEE P802.15.

  2. Proposed Resolution of D0 Comment S10-644 Kiran Bynam <author>, <company>

  3. 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>

  4. 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>

  5. 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
