  2. Outline • Comments to be resolved: • CID# 627, 628, 631, 632, 634, 635, 636, 639, 640, 666 • Recommend Resolution • Resolution Detail

  3. Comments & Recommend Resolution • CID# 627: • Comment: The value BandEdge is not defined for the standard defined PHY • Recommend Resolution: Accept in principle • CID# 628: • Comment: The maximum value for NumChan is not defined for the standard defined PHY • Recommend Resolution: Accept in principle • CID# 631: • Comment: the value of Bandedge in each frequency band is not defined clearly • Recommend Resolution: Accept in principle

  4. Comments & Recommend Resolution (Cont’d) • CID# 632: • Comment: Channel separation units is MHz??? It should likely be kHz? How large is the register? What is the granularity? • Resolution: Withdraw • CID# 634: • Comment: For each standard-defined PHY mode and Frequency band, BandEdge and the number of channels shall be specified • Recommend Resolution: Accept in principle • CID# 635: • Comment: Equation 1 is incomplete • Recommend Resolution: Accept in principle Slide 4

  5. Comments & Recommend Resolution (Cont’d) • CID# 636: • Comment: (1) shall be clarified whether it should be "= BandEdge+(NumChan+0.5)*ChanSpacing" or "=CenterFreq(Ch. 0)+NumChan*ChanSpacing". • Recommend Resolution: Accept in principle • CID# 639: • Comment: Channel numbering for OFDM is missing. • Recommend Resolution: Accept in principle • CID# 640: • Comment: Channel numbering needed for OFDM • Recommend Resolution: Accept in principle • CID# 666: • Comment: Channel numbering for the OFDM PHY is missing. • Recommend Resolution: Accept in principle Slide 5

  6. Resolution • Change the title of Clause 6.1.2.5a.3 to “Channel numbering for MRFSK PHY and OFDM PHY” • Change the text “where BandEdge is the start of the frequency band in MHz” to “where BandEdge is the start of the frequency band in MHz as shown in Table 1” on line 4 of page 23 • Add “GL is guard band on the lower side of the band, GH is guard band on the higher side of the band” after “…in MHz” on line 4 of page 23. Replace equation (1) on line 9-10 of page 23 with the following equation and text: ChanCenterFreq = BandEdge + GL + (NumChan + ½) x ChanSpacing, NumChan=0,…, TotalNumChan-1 (1) For Japanese bands, GL is 0.9 MHz, GH is 0.5 MHz for 200 kHz and 600 kHz Channel Spacing and 0.7 MHz for 400 kHz Channel Spacing. For all other bands, both GL and GH are ChanSep/2. TotalNumChan is the total number of channels for the available frequency band, TotalNumChan= floor( ) where W is the width of the available band.
