516 25.5.3.1.2 176 61 T In 802.11 REVmc, a new 7/8 rate Consider to add a 64-QAM is added. Consider if the 7/8 rate 64-QAM, same case exists in 11aj. as the same way of 802.11 REVmc. Discussion: In 802.11REVmc D8.0, there are 3 additional new MCSs in Table 20-19 compared to 802.11aj D3.0. The implementation of 2.16 GHz is easily be reused by 1.08 GHz PHY, so these 3 new MCSs should be accepted in 11aj. However, the MCS index has not been resolved yet for the new MCSs. So, it is better to accept these new MCSs when all issues are solved. Proposed resolution: Reject CID Clause Page Line Type Comment Proposed Change 517 25.3.6.2 169 19 T The new defined "single More description frequency sequence on how to use this (SFS)" is stated that it is new SFS should used for I/Q imbalance be provided. Also, estimation. It is not clear the relationship how this SFS realizes between the SFS I/Q imbalance and CE fields estimation. should described. Discussion: Do as the suggested remedy. Proposed resolution: Revised Change the first paragragh of 25.3.6.1 as follows: preamble is the part of the PPDU that is used for packet detection, AGC, frequency “The offset estimation, synchronization, I/Q imbalance estimation, indication of modulation (SC) and channel estimation. The format of the preamble consists of a Short Training field followed by a Channel Estimation field. Figure 25-2 (SC preambles) illustrates the SC packet preamble.”
