Gama shall be always 1 for HE modulated fields. 528 Dong Guk Lee 26.3.9 154.6 it would need to be clarified the gamma value for pre-HE modulated fields defined the gamma for pre-HE modulated field by using the Equation (21-14), Equation (21-15), Equation (21-16) and Equation (21-17) in REVmc D5.2. Rejected. It is resolved by resolution of CID #293. 1676 Oteri 26.3.9 154.6 tone rotation for 40 and 80 MHz not defined define tone rotation for 40 / 80 MHz Rejected. It is resolved by resolution of CID #293. 1980 Siguard Schelstraete 26.3.9 154.6 Missing part of sentence "In HE modulated fields, in all the subcarriers." is not a sentence. Something appears to be missing. Rejected. It is resolved by resolution of CID #293. 1982 Siguard Schelstraete 26.3.9 154.6 Redefining Gamma_k be confusing The notation Gamma_k is already used for HT and VHT. If the values are going to be different form those, use a different notation. Rejected. It is resolved by resolution of CID #293. 1983 Siguard Schelstraete 26.3.9 154.6 TBD Define. Similar on lines 41 and 49. Rejected. It is resolved by resolution of CID #293. 2417 Yongho Seok 26.3.9 154.6 For the pre-HE modulated fields, the Gamma should be determined. Use the same equation defined for a backward compatibility. As per comment Rejected. It is resolved by resolution of CID #293. 2418 Yongho Seok 26.3.9 154.6 For the pre-HE modulated fields, the Gamma should be determined. Use the same equation defined for a backward compatibility. As per comment Rejected. It is resolved by resolution of CID #293. 2419 Yongho Seok 26.3.9 154.6 For the pre-HE modulated fields, the As per comment Rejected.
on transmit i_TX and frequency segment i_seg" CID Commenter Section Page Comment Proposed Change Resolution 1968 Siguard Schelstraete 26.3.9 150.56 correct definition of fc(iseg) The frequencies of the segments are independent of the PPDU. Change "the center frequency of the portion of the PPDU transmitted in frequency segment iseg" to "the center frequency of frequency segment iseg" Accepted. CID Commenter Section Page Comment Proposed Change Resolution 1970 Siguard Schelstraete 26.3.9 151.25 Formula (26-3) should account for the case where HE-SIG-B is not present. Stating that is undefined (as on line 51) if the PPDU is not MU doesn't work in formula (26-3) Revised. Change to as in the resolution of CID1970 in doc ax editor: please make the following changes in D0.4 Clause 26.3.9: On P151L25 (CID #1970): On P151L31 Add “ is only applicable to an HE MU PPDU.” after “where”. CID Commenter Section Page Comment Proposed Change Resolution 1977 Siguard Schelstraete 26.3.9 152.38 notation not used in (26-4) Contrary to what is said on line 42, the notation N^Tone_Field is not used in (26-4). Instead N^Tone_Field is used in the defintion of beta_r (page 99) Revised. Change to as in the resolution of CID1977 in doc 1978 Siguard Schelstraete 26.3.9 153.48 |Kr| and Kr^Field are not used in (26-4), only in the definition of beta_r Move them to be sub-bullets of beta_rused in the defintion of beta_r (page 99) Revised. Change to as in the resolution of CID1978 in doc
ax editor: please make the following changes in Clause 26.3.9: On P152L38 (CID #1977): Move definition of and 26-13 after equation (26-6), the definition of. On P153L.48 (CID #1978): Move definition of and to be the sub-bullets of . CID Commenter Section Page Comment Proposed Change Resolution 1971 Siguard Schelstraete 26.3.9 152.2 PE is not defined as an inverse Fourier transform The text reads "each subfield is defined to be an inverse discrete Fourier transform". This is not true for the PE field. Revised. Change to as in the resolution of CID1971 in doc 1973 Siguard Schelstraete 26.3.9 152.9 subscript should be "subfield" instead of field (26-4) is a defintion of a subfield, not a field. Subscript of the right-hand side of the equation should be corrected. Rejected. Equation is a definition of field, , which sums subfields over k, m, and u. 1974 Siguard Schelstraete 26.3.9 152.2 Field -> subfield Change "each field" to "each subfield" and correct subscript in equation (26.5) and on line 23. Rejected. Equation is a definition of field , which sums subfields over k, m, and u. 1976 Siguard Schelstraete 26.3.9 152.4 Change "Equation 26-4" to "Equations 26-4 and 26-5" See comment Revised. Change to as in the resolution of CID1976 in doc Discussion: The commenter is that PE is not defined as an inverse Fourier transform. But Equation (26-4) is a definition of , which sums subfields over k, m, and u. We can rephrase the sentence to make it clear. ax editor: please make the following changes in D0.4 Clause 26.3.9: On P152L2 (CID #1971), On P152L4 (CID #1976): In an HE SU PPDU, HE MU PPDU and HE extended range SU PPDU, each field , , is defined as the summation of one or more subfields subfield is defined to be an inverse discrete Fourier transform.
