In 9.22.4.2.1 General Proposed resolution: Revised. At 1552.34, change “The request may be sent for ACs for which the ACM subfield is 0”. to: “The ADDTS Request frame may be sent for ACs regardless of the ACs’ ACM settings.”. CID Page Clause Resn Status Comment Proposed Change Ad-hoc 5214 This paragraph does not acknowledge that the times at which the AP transmits during an unscheduled SP may be additionally constrained by the coexistence mechanism. Add a statement to this para somewhere: "The times at which an AP may transmit during an unscheduled SP might be constrained by the Coexistence mechanism (see 10.2.2.5.2)." MAC Discussion Cited text: Agree with commenter that adding a statement might be helpful. Proposed resolution: Revised. At the end of cited paragraph, add "The times at which an AP may transmit during an unscheduled SP might be constrained by the U-APSD coexistence mechanism (see 10.2.2.5.2)." CID Page Clause Comment Proposed Change Resolution Owning Ad-hoc 5218 1560.62 10.2.2.10 This subclause acknowledge the coexistence mechanism, which has a whole raft of rules about receive operation. Add a sentence, "For receive operation using the U-APSD coexistence mechanism, also see 10.2.2.5.2." MAC APSD
Assigned to Solomon Trainin Proposed resolution: TBD. Comment Proposed Change Owning Ad-hoc "Wait until the ProbeDelay time has expired": but there is no such variable in the MLME. The only value of ProbeDelay available is that from the most recent invocation by the SME of one of the three primitives: MLME-SCAN.request, MLME-JOIN.request, or In the current context (after the primitive has run) the appropriate primitive appears to be either the MLME-JOIN.request or the MLME-START.request, so the text needs to specify either of those as the source of the value of the ProbeDelay parameter. Replace "Waiit until the ProbeDelay time has expired" with "Wait until the time indicated by the ProbeDelay parameter (from the most recent SME invocation of either the MLME-JOIN.request or the MLME-START.request) has expired" MAC Discussion I couldn’t find the quoted text at cited location 1550.34. guest the commenter may comment on “until a period of time equal to the ProbeDelay has transpired.”: The commenter mentioned two primitives: MLME-JOIN and MLME-START. However, in the current context (after the MLME-POWERMGT.request primitive has run), think the appropriate primitive appears to be the MLME-JOIN.request only, not MLME-Start.request. The MLME-Start.request is for “the MAC entity start a new BSS or become a member of an MBSS.”. Therefore, only MLME-JOIN.request need to be Proposed resolution: Revised. At the cited location, change “until a period of time equal to the ProbeDelay has transpired " to “until a period of time indicated by the ProbeDelay parameter from the most recent MLME-JOIN.request primitive has transpired.” Comment Proposed Change Owning Ad-hoc "a STA shall inform the AP through a successful frame exchange" -- in an unlicensed band "shall do something successfully" is not a valid requirement for compliance Reword in terms of what the STA shall do "transmit" and how it responds to both successful and unsuccessful outcomes of the attempted transmission.

in response to PS-Poll from the STA. When all ACs associated with the STA are delivery-enabled, AP transmits one BU from the highest priority AC that has a BU." -- in the first case it would be advisable if high-priority traffic were, like, prioritised transmit the BU from the highest priority AC that is not delivery-enabled and that has a BU." Discussion Cited text: Proposed resolution: Revised. After the first sentence cited, add: “The AP should transmit the BU from the highest priority AC that is not delivery-enabled and that has a buffered BU.” Comment Proposed Change Owning Ad-hoc What does "A STA may use both WNM-sleep mode and PS mode simultaneously." mean? Clarify, or demote to a NOTE MAC Discussion Cited text: Don’t think we need additional clarification. Okay to change it to a note. Proposed resolution: Revised. Change “A STA may use both WNM-sleep mode and PS mode simultaneously.” To “NOTE-- A STA can use both WNM-sleep mode and PS mode simultaneously.” CID Page Clause Comment Proposed Change Owning Ad-hoc 10.2.2.15.1 When TDLS is used without QoS, TPU cannot be used.
