  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Resolution for Modulation related Generic PHY comments] Date Submitted: [July 15, 2010] Source:[Kuor Hsin Chang1, Bob Mason1, J.L.Taylor2] Company: [Elster Solutions1, DTC (UK)2] Address: [] Voice: [] E-Mail:[kuor-hsin.chang@us.elster.com, robert.t.mason@us.elster.com, larry.taylor@discretetime.com] Re: [Comment Resolution for TG4g draft] Abstract:The presentation provides resolution for some channelization related comments Purpose: Presented to the 802.15.4g SUN Task Group for consideration and discussion Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.

  2. Outline • Comments to be resolved: • CID# 606, 609, 624, 1145, 1149, 1185, 1203, 1204, 1205, 1206, 1215, 1786 • Recommend Resolution • Resolution Detail

  3. Comments & Recommend Resolution • CID# 606: • Comment: The mode descriptor works for FSK but no other modulation type. That's not very "generic". • Recommend Resolution: Accept in principle • Resolution detail: Generic PHY will only be defined for FSK in the next draft. OFDM and O-QPSK modulation schemes are not defined for Generic PHY. • CID# 609: • Comment: Document says: "FSK is the only modulation scheme with defined parameters.“ (Propose “This generic PHY mechanism should allow other types of modulation to be defined with their specific parameters.”) • Recommend Resolution: Accept in principle • Resolution detail: Resolution same as CID# 606. • CID# 624: • Comment: should define the OFDM modes for Generic PHY descriptor • Recommend Resolution: Reject • Resolution detail: Resolution same as CID# 606.

  4. Comments & Recommend Resolution (Cont’d) • CID# 1145: • Comment: The generic PHY descriptor includes a "modulation scheme" field. When ModulationScheme = 1, OFDM FFT size should be defined • Recommend Resolution: Accept in principle • Resolution detail: Resolution same as CID# 606 • CID# 1149: • Comment: The generic PHY descriptor includes a "modulation scheme" field. When ModulationScheme = 2, relevant DSSS parameters should be defined. • Recommend Resolution: Accept in principle • Resolution detail: Resolution same as CID# 606 • CID# 1185, 1203, 1204, 1205, 1206: • Comment: Lines 22-31. Since Generic PHY parameters for OFDM and O-QPSK are not defined, in the Range field, mark values 1-3 as reserved for ModulationScheme and delete "NOTE — if specific parameters are not defined for the other modulation schemes, values 1–3 will be left as reserved." • Recommend Resolution: Accept Slide 4

  5. Comments & Recommend Resolution (Cont’d) • CID# 1215: • Comment: Additional modulation types should be called out as a future ammendment to this specification. • Recommend Resolution: Reject • Resolution detail: Resolution same as CID# 606 • CID# 1786: • Comment: OFDM should be removed from the generic PHY. • Recommend Resolution: Accept Slide 5
