CID Section Page. Line Comment Proposed Change Resolution 1318 Adrian Stephens 24.3.8.2 283.28 "Greater than or equal to 2MHz PHY" I don't think Clause 24 defines multiple PHYs. It defines a single PHY with multiple formats. Change title to relate to PPDU format. Accept. See reproduced text for applied changes. 1319 Adrian Stephens 287.53 "NOTE--Integer fields are represented in unsigned binary format with the least significant bit in the lowest numbered bit position." This should not be a note, because this information is necessary for interoperability. Promote to body text. Accept. See reproduced text below for applied changes. 1320 Adrian Stephens 289.05 "(AMPDU)" - terminology Replace all "AMPDU" with "A-MPDU" Accept. See reproduced text below for applied changes. 1321 Adrian Stephens 291.19 The "0" dots in figure 24-28 have drooped. Raise them up. Ditto at 300.57 on the left. Accept. See reproduced text below for applied changes. 1322 Adrian Stephens 292.38 " long preamble is always single user modulated" -- the 'reassurance' given by "always" is unnecessary. " long preamble is single user modulated. Accept. See reproduced text below for applied changes. 1323 Adrian Stephens 295.65 More red text make it Accept. See reproduced text below for applied changes. 1324 Adrian Stephens 309.01 Notes within a subclause are numbered consecutively. Change previous note to "NOTE 1<em-dash>", and this one to "NOTE Review all NOTEs in the draft and ensure any multiples within the same subclause are numbered. Accept. See reproduced text below for applied changes. 1567 Bo Sun 284.32 the expain of NSR is missing chang to NSR is defined Table Accept. See reproduced text below for applied changes.
reflected in the SIG diagram 1614 Hart 288.33 "B10-B15 are set to the value of the TXVECTOR parameter PARTIAL_AID" but the TXVECTOR table indicates PARTIAL_AID ranges from 0-511 Need to define a restriction on PARTIAL_AID in the TXVECTOR table OR how to crop 9 bits down to 6 bits (or a ref) Reject. The Partial AID in TXVECTOR can either be 9-bits or 6 bits. The definitions are in Section 9.17b Group ID, partial AID, UPLINK, and Color in S1G PPDUs. When a >=2MHz PPDU is sent by an AP and is addressed to a STA associated with that AP, the formula is: (dec(AID[0:8])+ dec(BSSID[44:47] xor BSSID[40:43])×2^5 ) mod 2^6. 1761 Edward Reuss 291.20 Figure 24-28 indicates that the QBPSK constellation is either +1j or something less than -1j. Shouldn't this be +1j and -1j? Modify Figure to indicate the constellation contains +1j and Accept. See reproduced text for applied changes. 1762 Edward Reuss 300.58 Figure 24-34 indicates that the constellation for SIG-A-1 can be either +1j or something less than -1j. I assume that this is a diagram error. Also, are they and or should they be labeled "SIG-A1" and SIG-A2"? Fix Figure 24-34. Accept. See reproduced text for applied changes. 1765 Eugene Baik 308.13 Equation 24-37 for LTF1 is incorrect. The P-matrix factor should be as all symbols for LTF1 receive same mapping (n=1, first column) In equation 24-37, change to Accept. See reproduced text for applied changes. 1766 Eugene Baik 308.20 Equation 24-38 for LTF1 is incorrect. The P-matrix factor should be In equation 24-38, change to Accept.

calculations for 11ah 1770 Eugene Baik 310.18 Coding bits in Table 24-18 define how LDPC codeword lengths are calculated, and reference Section 22.3.10.5.4 of the 11ac spec and Section 20.3.11.6.5 of the 11n spec. These specs assume the Service field length is 16 bits when it is now 8 bits for 11ah. Need to define 11ah-specific LDPC length calculations for 11ah Need to create new section in 11ah spec to specify LDPC length calculations. Coding bit definition should reference this section Reject. Length, Number of symbol (N_sym), and available bits (N_pld) equations in Section 22.3.10.5.5 LDPC coding of 11ac spec are still applicable because number of service bits (N_service) are treated as variable. 1782 Eugene Baik 287.17 The 2MHz frame SIG definition needs an Uplink indication bit Add a field in the SIG bit map and definitions table for Uplink indication Revise Previous CID resolution 12/1207r1 addresses this, the Uplink indication definition has been added. For editor: no change necessary to current Draft 1.1. 1783 Eugene Baik 295.01 The 2MHz long frame SU SIG definition needs an Uplink indication bit Add a field in the SU SIG bit map and definitions table for Uplink indication Revise Previous CID resolution 12/1207r1 addresses this, the Uplink indication definition has been added. For editor: no change necessary to current Draft 1.0. 2073 Jens Tingleff 285.31 LTF fields in clause 22 are not defined in equations 22-32 and friends. equations are still in the STF part of clause 22.) Figure out correct reference Accept. See reproduced text below for applied changes. 2074 Jens Tingleff 285.42 (Equation 24-14) The dot before the second open square bracket looks like it should be an implied multiplication.
