CID Commenter Clause Page/Line Comment Proposed Change Resolution 11496 Chunyu Hu 28.3.10.8.6 432.32 is no definition of load balancing before usage. Load balancing is a general term in network, but is complete new in this new context of HE SIG-B. It's not clear what it means in this section. Please define it before using it in the text of behavior description. as in the comment Revised Editor please make changes shown in document under comment 11496 11530 Dorothy Stanley 28.3.10.8.5 426.48 something is weird with the formatting. Its seems like "Use the same value in both HE-SIG-B content channels." should be part of the 80 MHz description, but its looks like its in the paragraph with the 160 MHz section. Please clarify. as in comment Revised. Editor: remove the gap above that sentence and add a gap below it. Also change that sentence as follows: Use The same is applied to in both HE-SIG-B content channels 11636 Dorothy Stanley 28.3.10.7.2 405.25 The title of Table 28-18 is field of an HE SU PPDU and HE ER SU PPDU", so why would B0 of HE-SIG-A1 ever be "set to 0 for HE TB PPDU"? You probably just want to say "set to 1 for HE SU PPDU and HE ER SU PPDU", and not say anything about HE TB PPDU. as in comment Revised. Editor please make changes shown in document under comment 11636
11695 Erik Lindskog 28.1.1 328.01 We are here referring to the regulatory requirements of VHT. Add a separate section for regulatory requirements under Clause 28. Rejected: No need to repeat the same text twice 11719 Fei Tong 28.1.1 376.65 Option support for Mid-amble should be included in the list HE STA may support Add mid-amble to the optional support list Revised Editor: Refer to the resolution of CID 13622 in 37r1 11864 Guoqing Li 28.1.4 331.60 Support of HE MU PPDU is mandatory in DL, but optional in UL. Please clarify. Clarify Revised Editor please add at the end of line 61 the following: for transmission for AP and reception for STA Mark RISON 28.1.1 329.20 It is not clear that HE APs shall support (at least) 2SS At the end of the list "An HE AP shall support the following features:" add "Transmission and reception of PPDUs with two spatial streams" Rejected: are mobile AP that don’t need to support 2SS. That decision is best left to WFA 12639 Mark RISON 28.3.10.8.6 432.31 "In the case of load balancing for RUs of size greater than 242 subcarriers where user fields corresponding to the same allocations are split into two HE-SIG-B content channels, the user-field positions are logically continuous with the first user field corresponding to the same RU in the second content channel updating its position (and Delete the cited text Revised.

13371 ron porat 28.3.10.8.5 428.00 To cover certain legal allocation in 80, 160 or 80+80 OFDMA cases when for a particular content channel, one 996-tone RU Allocation subfield has non-zero number of users while the other 996-tone RU allocation subfiled has no users, change to RU with no User fields indicated by this RU Allocation subfield". Revise as suggested Revised Editor: See resolution for comment 13407 13407 Rui Cao 28.3.10.8.3 424.04 When RU=996 is allocated, the setting of the RU Allocation Bits is not clearly defined. The totally number of in one 996RU will be split in two content channels with load balancing. However, each 996RU will have 16 RU Allocation bits, and 8-bit RU Allocation 11010yyy can already clearly specify the number of users signaled in the corresponding content channel. How to set the second 8 bits is not specified in current text. Propose to add the following to the paragraph, "If RU equals 996, the first 8 RU Allocation bits will use entry 11010yyy as in Table with yyy indicating the number of users signaled in the corresponding content channel, while the second 8 RU Allocation bits will be set to 01110011". In addition, change the description of entry "01110011" in Table 28-24 to "996-tone RU with zero User indicated in this RU Allocation subfield of the HE-SIG-B content channel". Revised: Editor please make changes shown in document under comment 13407
14080 Youhan Kim 28.3.10.8.3 424.54 Consider a RU. There are four RU Allocation tables in which one or more User field(s) could be signalled, with two RU Allocation tables in a given HE-SIG-B content channel. But within a given content channel, there is no benefit in signaling non-zero User fields in the RU Allocation table which is not the first one in the HE-SIG-B content channel (e.g. there is no saving in the number of User fields). Similar example holds for RU2x996. Add rule indicating that in case of or RUs, only the first RU Allocation table in each content channel may have non-zero users. Subsequent RU Allocation tables in each HE-SIG-B content channel shall indicate zero users. Revised Editor: see resolution to comment 13407 13638 Tianyu Wu 28.3.10.8.3 424.04 Signaling of 996 RU in 160/80+80 Mhz PPDU need to be clarified. Add a paragraph clarifying the 996 RU signaling. will be 4 RU allocation subfields in total, each HE SIG B content channel carries 2 RU allocation subfields. Revised Editor: see resolution to comment 13407 11531 Dorothy Stanley 28.3.10.8.5 428.01 What does "Number of entries" mean for cases that are "Reserved" in Table 28-24? as in comment Rejected: It simply means the number of reserved entries 11532 Dorothy Stanley 28.3.10.8.5 428.41 Table 28-24, Regarding "10y2y1y0z2z1z0", how do you multiplex 64 users together in three RUs? as in comment Rejected: The number 64 indicates the total combinatorial options of multiplexing up to 8 users on each 106RU using DL MU-MIMO. It is
not indicating 64 users are being multiplexed 13239 Robert Stacey 9.4.2.237.3 140.62 The only difference between class A and class B devices is power control accuracy. The terminology is thus misleading not aligned with other capability naming. Change the field name to "Tx Power/RSSI Accuracy" (or even "Power Control Accuracy") with enumerated values High and Low. Change the middle column heading in Table 28-43 to "Tx Power/RSSI Accuracy subfield" with sub-columns "High" and "Low". Updated the places where Class A and Class B are used appropriately. Rejected Change seems an over kill. The proposed change may confusion in the text 13305 Robert Stacey 28.3.10.7.2 405.40 The description is not accurate -- see 27.11.2. Also, is nothing in the PHY that links it to UPLINK_FLAG. You don't need any shall statements here - they are in the MAC section. Change the desciption so that it references TX/RXVECTOR parameter UPLINK_FLAG. Revised Editor – please replace the description of that field with “Indicates whether the PPDU is sent UL or DL as described by the TX/RXVECTOR parameter UPLINK_FLAG” 13460 Sigurd Schelstraete 28.3.10.7.2 413.10 "Spatial Reuse field applies to the first 20 MHz subband.". Clarify "first" See comment Rejected: description exists below the table
13461 Sigurd Schelstraete 28.3.10.7.2 413.15 "Spatial Reuse field applies to the first 40 MHz subband.". Clarify "first" See comment Rejected: description below the table 13462 Sigurd Schelstraete 28.3.10.7.2 417.06 "the encoding for the Spatial Reuse 1, Spatial Reuse 2, Spatial Reuse 3 and Spatial Reuse 4 subfields for an HE SU PPDU, HE ER SU PPDU, and HE MU PPDU." These PPDU formats have only one Spatial Reuse field. Correct Revised: Editor please revise as follows 2, Spatial Reuse 3 and Spatial Reuse 4 subfields 13601 SUNGEUN LEE 28.3.10.7.2 417.06 Table 28-21 is SR for HE SU, HE ER SU and HE MU. HE-SIG-A for those PPDUs only have one SR field, i.e., no Spatial Reuse 1, 2, 3 and 4 Change 'Spatial 1, Spatial Reuse 2, Spatial Reuse 3 and Spetial Reuse 4 subfiels' to 'Spatial Reuse subfield' Accepted : As in comment 13462 14072 Youhan Kim 28.3.10.7.2 416.45 What does "The Spatial Reuse fields only apply to 20 Mhz used in the transmission" mean? Clarify what "The Spatial Reuse fields only apply to 20 Mhz used in the transmission" means. Revised: Editor please delete the two instances of this sentence on lines 45 and 42 and add the following on page 417 line 4 (above the description of table 28-21): “Each Spatial Reuse field is applicable only if the corresponding 20MHz is occupied by at least one RU”
