CID Section Page. Line Comment Proposed Change Resolution 1318 Adrian Stephens 24.3.8.2 283.28 "Greater than or 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 below 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 - 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 black 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 (Timing-related constants) Accept. See reproduced text below for applied changes. 4
1568 Bo Sun 284.32 the parameter of Qk is not defined in equation (24-13), also missing in the time domain representation of signal of preamble. add the definition of Qk under formula that uses Qk throughout the spec Accept. See reproduced text below for applied changes. 1572 Bo Sun 311.35 For 1MHz PPDU, the roatation of SIG field symbols makes no sense. For example, in 11ac, the rotation is used to distinguish VHT format from HT format. In S1G 2MHz PPDU, the rotation is used to distinguish short preamble from long preamble. Delete the term "rotated" in this section Accept. See reproduced text below for applied changes. 1610 Brian Hart 287.56 "The SIG field is composed of two OFDM symbols, SIG-1 and SIG-2, each containing 24 data bits, as shown in Table 24-11" Due to BCC encoding the end data bits in SIG1 are spread into SIG2, so not correct to say "each containing 24 data bits" Instead talk about first part and second part containing 48 bits total ... (see 11ac for the template) Accept. See reproduced text below for applied changes. 1611 Brian Hart 287.31 "reserved" is lowercase Reserved Accept. See reproduced text below for applied changes. 1612 Brian Hart 288.26 UPLINK - is the is the TXVECTOR parameter or the SIG field? Be specific. Better still, lowercase the field name Revise. Rename SIG entry as Uplink Indication, which will have same value as UPLINK of TXVECTOR 1613 Brian Hart 288.31 "If UPLINK is set to 0, B7-B9 are set to the value of the TXVECTOR parameter COLOR and B10-B15 are set to the value of the TXVECTOR parameter PARTIAL_AID." is SIG structure not reflected in the SIG diagram Need to reflect this explosion in Fig 24-26/27 Reject. The field ID is properly described in Table 24-11. Description clearly indicates how the bits of the “ID” field in the SIG should be populated.
1614 Brian Hart 288.33 "B10-B15 are set to the 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 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 ) mod 2^6. 1761 Edward 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 below 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 below 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 as all symbols for LTF1 receive In equation 24-38, change to Accept. See reproduced text below for applied changes.
