  2. An interleaving method in OFDM frame example for LB67 March, 2011 IEEE 802 Plenary Session Singapore March 2011 Cheolho Shin & Sangsung Choi Slide 2

  3. March, 2011 • Summary • For CID 22 and 550 • Comment : Consider the modified Interleaving factor 'Nrow‘ • Proposed change: Change Nrow From 12 to 3 for OFDM option2 and MCS 0. • Refer to Slide 4 for Draft 2(D2) and Slide 8 for Draft 3(D3) in this document . • For CID 23 and 551 • Comment : Reconsider the results of Interleaving for J.4 • Proposed change: Refer to Slide 6 and Slide 7 in this document. In D2, Slide 6 was used to generate the interleaving results Table J.8. But, Slide 7 is correct interleaving method. • For CID 24 and 552 • Comment : Insert an example for 'PIB attribute phyOFDMInterleaving = 1‘ • Proposed change: Refer to Doc.213. Slide 3

  4. March, 2011 Interleaving method for OFDM option 2 and MCS level 0 in D2 - When the PIB attribute phyOFDMInterleaving is zero, Ncbps is 12 and Nrow is 12. -> In this configuration, no bit interleaving is necessary. Slide 4

  5. March, 2011 Interleaving method for OFDM option 2 and MCS level 0 in D2 - When the PIB attribute phyOFDMInterleaving is one, Ncbps is 48 and Nrow is 12. Slide 5

  6. March, 2011 Interleaving method for OFDM option 2 and MCS level 3 in D2 - When the PIB attribute phyOFDMInterleaving is zero or one, Ncbps is 96 and Nrow is 12. -> Following interleaving method was used in Table J.8 of Annex J Slide 6

  7. March, 2011 Interleaving method for OFDM option 2 and MCS level 3 in D2 - When the PIB attribute phyOFDMInterleaving is zero or one, Ncbps is 96 and Nrow is 12. Slide 7

  8. March, 2011 Interleaving method for OFDM option 2 and MCS level 0 in D3 - When the PIB attribute phyOFDMInterleaving is zero, Ncbps is 12 and Nrow is 3. Slide 8

  9. March, 2011 Interleaving method for OFDM option 2 and MCS level 0 in D3 - When the PIB attribute phyOFDMInterleaving is one, Ncbps is 48 and Nrow is 3. Slide 9

  10. March, 2011 Interleaving method for OFDM option 2 and MCS level 3 in D3 - When the PIB attribute phyOFDMInterleaving is zero or one, Ncbps is 96 and Nrow is 12. Slide 10
