Here the corresponding description for DMG STA is changed in REVmc D5.4 based on REVmc comment resolution. Change to "The CDMG PHY operates in the channels defined in Annex E and shall support at least channel number 2, 5 and 6." in accordance with REVmc D5.4. Do the same throughout the draft. Proposed resolution: Accepted. Change the sentence as follows: "The CDMG PHYSTAs compliant with the physical layer defined in Clause 25 (China Directional Multi-Gigabit (CDMG) PHY specification) operates in the channels defined in Annex E and shall support at least channel number 2, 5 and 6." CID Comment Proposed Change Remark 427 B 267 10 E Insert abbreviations used in Annex B.4 such as "CDMG-M", etc. in Annex B.2.2, Per comment. Proposed resolution: Reserved. Insert the following abbreviations in Annex B.2.2: “B.2.2 General abbreviations for Item and Support columns CDMG-M China directional multi-gigabit (CDMG) medium access control (MAC) features CDMG-P China directional multi-gigabit (CDMG) physical layer (PHY) features 45MG-M 45 GHz (45MG) medium access control (MAC) features 45MG-P 45 GHz (45MG) physical layer (PHY) features”
CID Comment Proposed Change Remark 406 164 41 T The formula seems to have an error. According to the formula and the parameters in Annex E, the center frequencies of channel number 2,3,5,6,7, and 8 are calculated as 63.72, 65.88, 60.48, 61.56, 62.64, and 59.40 [GHz] respectively and they don't match with the figure in For 2.16 GHz band, DMG specification (i.e. 20.3.1 Channelization) can be referred. For 1.08 GHz band, suggest the following formula and parameters: Channel center frequency = Channel starting frequency + Channel spacing x (Channel number mod 32) where Channel starting frequency is 56.70 GHz, Channel spacing = 1080 MHz, and Channel numbers are {35,36,37,38} instead of {5,6,7,8} respectively. This re-numbering enables regular numbering, and also avoids conflict with 11ay channelization seen in SFD). 407 E.1 284 27 T The channel starting frequencies for operating class 10 and 11 may be incorrect. The channel starting frequencies and/or the formula in 25.3.1 (Channelization) should be corrected. As the same as CID 406 Proposed resolution: Accepted. Change the starting frequency from “59.4 GHz” to “56.16 GHz” and “59.4 GHz” to “56.70” for Operating class 10 and 11 respectively. Change the formula in clause 25.3.1 in 11aj is as follows: “Channel center frequency = Channel starting frequency + Channel spacing × (Channel number mod 324)” Change Table E-5 in Annex E as follows: Operating classes in China

CID Comment Proposed Change Remark 409 T To ensure coexistence, 11aj should the same BW mode and compatible preamble structure as 11ad when operating in bands where 11ad can also operate in. To ensure coexistence, 11aj should the same BW mode and compatible preamble structure as 11ad when operating in bands where 11ad can also operate in. Proposed resolution: Rejected. 802.11aj was formed as a platform for collaboration between 802.11 and China wireless personal area network (CWPAN) working group. According to the radio regulations in China, there are only two physical 2.16 GHz bandwidth unlicensed
CID Comment Proposed Change Remark 422 10.7 87 47 T is no multirate support for CDMG STAs. Insert txt to enable multirate support for CDMG STAs. Proposed resolution: Revised. In general, CDMG STAs follow the same rule regarding the multirate support defined for DMG STAs in 10.7 (Multirate support). While some parameters of CDMG STAs are different from those of DMG STAs in PHY layer, so some changes are necessary to support this feature for CDMG STAs.

Copy and paste errors. Here "DMG" should be "CDMG". Change to "Depending on the CDMG MCSs, these STAs support a mixture of CDMG SC mode, CDMG low-power SC mode, and CDMG control mode." Correct the similar error throughout the draft. Proposed resolution: Accepted. Change the sentence as follows: "Depending on the CDMG MCSs, these STAs support a mixture of CDMG SC mode, CDMG SC mode, and CDMG control mode."
