It is also necessary to clarify the Advenced CPE (A-CPE). Clarification of the diffrence of these A-BS and A-CPE from conventional BS and CPE defiend in the IEEE 802. 22 -2011 main standard should be described. Creating additional table to show the comparison of A-BS, A-CPE and conventional BS and CPE looks desirable. 22 -14 -99/r 0 Shigenobu Sasaki Add additional abbreviations and acronyms, if necessary. 47 48 Comment Access Zone is used in both PHY mode 1 and PHY mode 2, but the description is not complete for PHY mode. The "Local SID Group" in Table P 1 seems same as the "SID If right, remove subclause 7. 7. 7. 3. 6 and replace "Local SID Bitmap of Group" in Table AR 1. Group" with "SID of Group". QPSK and code rate 1/2 are not defined. The coding scheme should also be defined. What is the purpose of "Local Cell Update" in subcluase Sunghyun Hwang 7. 7. 25?

Sunghyun There is no need to describe the Hwang implementation method in this subclause. Submission Suggested Remedy Move properly clause 14 to clause 9 or 9 a. Refer to other IEEE 802 standard. Remove the implementation method, such as combiner, estimator, etc. Or move it to appendix as an informative text.

In Table GQ 1, 192 TCM) should be made clear and the maximum on the other hand, on the column of 1/16 CP of data rate in Table 198 and in Table GQ 1 should be 6 MHz BW, the maximum data rate is 32. 12 Mbit/s. the same. The maximum data rate should be the same value. 22 -14 -xx/r 0 This may affect the data rate in PHY Mode 2. Ivan Reed My major disagreement with the draft as it Accept in principle. Add a paragraph in the purpose 22 -14 -85/r 0 stands is the fact that the 2 k FFT has been of 802. 22 b to th e effect that "The standard has reduced to a 1 k FFT. This causes problems on been deisgned to meet the needs required by both channel B operation and on filtering in channels A & C (check up please). In the rare compliance to the FCC spectrum mask.

It is not necessary to list all data rate corresponding to differennt CP in the tables. ID 45 Sunghyun Hwang 58 Sunghyun Hwang 87 Ranga Reddy 88 Ranga Reddy 89 Ranga Reddy 90 Ranga Reddy Submission Define the local frame preamble to support T segmentation scheme. Suggested Remedy Implementation Status PHY mode number should start from 5 (five) in the new tables. Pick up just one or two cases of CP ratio, and remove rest of them from data rate tables. I suggest to cover at least 1/16 CP, and 1/4 CP as an option. Accept: PHY mode number should start from 5 (five) in the new tables. Reject : : Pick up just one or two cases of CP ratio, and remove rest of them from data rate tables. I suggest to cover at least 1/16 CP, and 1/4 CP as an option. For the local frame preamble, the number of PN sequence should be defined considering the number of the used subcarriers for PHY mode 1 and PHY mode 2, respectively. 22 -14 -100/r 0 T There is no MIMO pilot pattern for PHY mode 1. Define the MIMO pilot pattern for PHY mode 1. TR Why have a separate GID here? This just add bits Identify groups by the SID of the group manageer, to the message. make that the first SID in the SID bitmap of GRACFG message. This also applies to the GRA-UPD message TR able AS 1 does not indicate clearly if Device_flag Try using a message type field 2 -3 bits, and 22 -14 -108/r 0 and Group_Flag are both necessary, structure the message accordingly. TR the GRA-UPD doesn't allow deleting more than Update message to include structure to handle 22 -14 -108/r 0 one CPE from the group at once. This would deletion of more than one CPE from a group cause multiple Tx's to delete more than one CPE TR here we say that the Backup/Candidate IE of Provide text indicating that grouping should be DCD can be used to update a group limited to distributed relays, and we don’t need backup/candidate list. The statement in the text modifications to DCD. similar changes would be here refers to modifications in table 22. Are applicable to UCD as well. these modifications to Table 22 even necessary, assuming that GRA methods are only applicable to distributed relays, which could transmit their own DCD/UCD in their zone.
