Editor: p 486, line 4, remove the equation number For EDMG OFDM transmissions using a single 2.16 GHz channel, the frequency sequence used to construct the EDMG-STF field for the iSTSth space-time stream is given by: CID 3720 Clause Number(C) Page(C) Line(C) Comment Proposed Change 29.6.2.6 481 10 SP should be the subscript of N in P_NSP As comment, also to line 8, 12, 22, and a global search and change is needed. Resolution: Revised. Editor: p 481, line 8, replace the notation/equation below with the corrected one The pilot value depends on the iSTSth space-time stream number, nth OFDM symbol, and kth subcarrier index and defined as follows: where: defines pilot for iSTSth space-time stream and kth subcarrier W(iSTS, n) × (2×p(n) – 1) defines a common phase shift (over subcarriers) for the iSTSth space-time stream and nth OFDM symbol, p(n) defines a bit coming from the scrambler defined in 29.6.9.1 with shift register x1, x2,…, x7 initialized to all ones at the zeroth (i.e., n = 0) OFDM symbol NSTS defines the number of space-time streams Editor: p 481, line 22, replace the notation with the corrected one The pilot sequence for given number of contiguous channel bandwidth, NCB, is defined in Table 99.

Clause Number(C) Page(C) Line(C) Comment Proposed Change 29.5.9.4.3 440 16 It's not clear what the code rate R should be for example a) listed here. In b.b)-k) there are explicit code rates listed, and they're computed L_CW*R, here R is implicit? Add a code rate R to example b)a. or rewrite all of b) in a different structure. Resolution: Revised. Editor: p 440, line 15, add the list of LDPC code used in the case b).a) as below Convert the scrambled PSDU bits to LDPC codewords as follows: If ρ = 1 and LCW = 672 1344: The output stream of scrambler is broken into the blocks of length LCWD = LCW×R bits such that the mth data word is To each data word, parity bits , LCWP = LCW - LCWD, are added to create the codeword such that Editor: p 495, line 7, add the list of LDPC code rates used in the case b).a) as below Convert the scrambled PSDU bits to LDPC codewords as follows: If LCW = 672 1344: The output stream of scrambler is broken into the blocks of length LCWD = LCW×R bits such that the mth data word is To each data word, parity bits , LCWP = LCW – LCWD, are added to create the codeword such that CID 3065 Clause Number(C) Page(C) Line(C) Comment Proposed Change 29.5.9.4.3 440 15 I write this entire section differently. Among subpoints a-k under subheading b, item b) a. is a general algorithm but for specified values of L_CW and and rho. Why not instead make a table of rho, L_CW and R, and give the general formula in b)a. , rather than repeating the same thing for different constants 10 times? Make a text such as: "The scrambled PSDU values are converted to LDPC codewords using the following strategcy, where starting values are listed in Table XX: ...." Then remove b)b.-k.
