IEEE P802.11 Wireless LANs LB202 Assigned comments Date: 2014-12-18 Author(s): Name Company Address Phone email Dorothy Stanley Aruba Networks 1322 Crossman Ave Sunnyvale, CA 94089 +1 CID 3741 (MAC) 3741 1623.40 10.9.3 The first sentence of the paragraph that begins at 1623.40 is about the AP and mesh STA transmissions. Then the second sentence begins: "Only the most recently received Beacon frame or Probe Response frame defines all future quiet intervals;" The subject of this paragraph is not receptions but transmissions. Replace "most recently received" with "most recently transmitted". Discussion: The cited text is below: The commenter’s proposed change is shown below: The AP or mesh STA may stop scheduling quiet intervals or change the value of the Quiet Period field, the Quiet Duration field, and the Quiet Offset field in Quiet elements as required or Quiet Channel elements with the AP Mode field equal to 1. Only the most recently Beacon frame or Probe Response frame defines all future quiet intervals; therefore, all schedules for quiet intervals based on older Beacon frames or Probe Response frames shall be discarded.
3554 33.35 3.2 What does this mean: "The activity level identifier of a mesh station (STA) set per mesh peering or for nonpeer neighbor STAs."? Presumably active mode, light sleep mode and deep sleep mode are mesh power modes -- yet their definitions only mention neighbor mesh STAs, not peering. So shouldn't this definition just say: "The activity level of a mesh station (STA) with respect to a neighbor mesh STA."? Replace "The activity level identifier of a mesh station (STA) set per mesh peering or for nonpeer neighbor STAs." with "The activity level of a mesh station (STA) with respect to a neighor mesh STA." 3555 33.39 3.2 Definition of mesh mode tracking: same problem as with the defintion of mesh power mode: the definitions of the apparent power modes (active mode, light sleep mode, deep sleep mode) are in terms only of neighbor mesh STAs. So why are neighbor mesh STAs not mentioned in this definition? Make all of the mesh power mode definitions consistent with each other. (Can't make a suggestion, since text is insufficient to determinine what is intended.) Discussion: The cited text is below: Proposed resolution for CID 3554: Rejected. The cited definition is correct, see clause 13.14. Neighbor STAs are either peered or non-peered. Proposed resolution for CID 3555: Rejected. The comment fails to identify changes in sufficient detail so that the specific wording of the changes that will satisfy the commenter can be determined. CID 3517, 3518 (GEN) 3517 9.20 3.1 "A quality-ofservice (QoS) BSS has one DCF and one HCF", no a QoS STA has one ... Change "BSS" to "STA"
3334 992.31 8.4.2.127.2 "The Higher Layer Timer Synchronization field is set to 1 if the STA supports Higher Layer Timer Synchronization as defined in 10.24.5" It's defined in 10.6, assuming this is really what was intended (cf. timing measurement) Discussion: The cited text is below: 10.6 is “Higher timer synchronization” 10.24.5 is “Timing measurement procedure” Proposed resolution: Revised At 992.31 change the section reference from 10.24.5 to 10.6. CID 3346 (GEN) 3346 26.01 3 The CBAP definition suggests EDCA is sometimes not used, but at least in an IBSS EDCA is always used, right? Clarify Discussion: The cited text is below: The commenter is asking if EDCA is always used in a CBAP. Discussion with Carlos Cordeiro: yes At 71.51: A DMG STA uses EDCA only within a CBAP At 1437.51: EDCA is used during the CBAP. Proposed resolution: Revised At 26.1 modify the definition as shown: contention access period (CBAP): The time period within the data transfer interval (DTI) of a directional multi-gigabit (DMG) basic service set (BSS) enhanced distributed channel access (EDCA) is used. CID 3353 (GEN)
3512 12.25 3.1 Can there be more than one Portal? (See definition of infrastructure, and Annex Q, in particular) If no, how does an 802.11 LAN connect to more than one non-802.11 LAN (or VLANs, see Figure V-1)? (Is a bridge required?) If yes, how does the DS know how to route outbound traffic - does the DS perform 802.1Q functionality? Could the DS create a "bridge" between the non-802.11 LANs, independent of the WLAN, and can it result in loops, etc? Clarify. Suggest that 802.11 assume there is only one portal (logically), so the DS can be well defined, and not require 802.1Q functions. Change the definition of "infrastrcture" and "WLAN system" to say "zero or one portal". Change Annex Q to match. Add a bridge in Figure V-1 to connect to the multiple VLANs. Discussion: The cited text is below: Discussion with Mark Hamilton: Discussions underway in ARC and 11ak; potentially have agreement on number of portals in November. Reference: from Mark Rison on 3314, 3493, 3141, 3394, 3292: “The use of the Dual CTS mechanism is deprecated” is probably most consistent with text. Similarly, “Dual CTS operation” is not a term which appears in the current draft (it's either dual CTS mechanism or dual CTS protection mechanism) Also 824.62, 1881.12, 1910.37 (D3.2) 2 instances of “RSN STA” (no A after RSN) in baseline too Well, except that there’s the statement ““TVHT-MCS” replaces “VHT-MCS”” in 4.3.13 and 23.5 is about “Parameters for TVHT MCSs” missing hyphen It’s more than unusual, it violates IEEE Std 802. Hence I think there should be a NOTE. Don’t ask me why, but like “ANQP-element”, “RLQP-element” takes a hyphen CID 3087 (GEN)
