IEEE P802.11 Wireless LANs LB215 TWT CIDs proposed resolutions Date: 2016-01-17 Author(s): Name Affiliation Address Phone email Matthew Fischer Broadcom 190 Mathilda Place, Sunnyvale, CA 94086 +1 408 543 3370 REVISION NOTES: R0: initial Interpretation of a Motion to Adopt A motion to approve this submission means that the editing instructions and any changed or added material are actioned in the TGmc Draft. This introduction is not part of the adopted material. Editing instructions formatted like this are intended to be copied into the TGah (i.e. they are instructions to the 802.11 editor on how to merge the text with the baseline documents). TGah Editor: Editing instructions preceded by “Instruction to Editor” are instructions to the TGah editor to modify existing material in the TGah draft. As a result of adopting the changes, the TGah editor will execute the instructions rather than copy them to the TGah Draft. CID LIST:
Information frame in response to the receipt of the frame” 8099 Adrian 127.50 What good is octet index 2 doing in Table 8-142b? Remove octet index 2 rows at cited location. Ditto Tables 8-142c and 8-142d. Reject – the cited tables contain an octet with reserved fields so that the format of the classifier mask fields of the classifiers 7, 8 and 9 match the format of the classifier mask field for classifier 6 to reduce the amount of variation in the classifiers. The frames in which these fields appear are transmitted only for setup of classifier operation and the tradeoff between saving a single byte for a rarely transmitted frame and providing consistent formatting was decided by the group in favor of consistency. 8116 Adrian 152.62 "A TWT responding STA setsthe TWT Protection subfield to 0 to indicate that the TWT SP(s) identified in the TWT element might not be protected from TIM STAs by allocating RAW(s)." -- way too many words. Replace with "Otherwise, set to 0". Accept
8310 Wang, 151.22 A STA could transmit multiple TWT requests for multiple TWT flows. However, the most recently received TWT response with ( a prior response) may be of a different group ID x than the group ID y of the TWT response without zero-offset (currently received response). In this case, STA should not use the zero-offset of group ID x as the for group ID y. Change the sentence "The receipt of a TWT response with a TWT Group Assignment field with no Zero Offset of the Group subfield implies that the Zero Offset of the Group subfield value for that TWT is the same as the Zero Offset of the Group subfield value for the most recently received Zero Offset of the Group subfield from the TWT Responding STA." into "The receipt of a TWT response with a TWT Group Assignment field with no Zero Offset of the Group subfield implies that the Zero Offset of the Group subfield value for that TWT is the same as the Zero Offset of the Group subfield value for the most recently received Zero Offset of the Group subfield for the same TWT group ID from the TWT Responding STA." Accept 8311 Wang, 299.59 9.44.3 If TWT responding STA sends the Next TWT value via STACK/BAT/TACK as described in L28~L39, then "the TWT responding STA shall queue for transmission a TWT Information frame that contains a nonzero Next TWT value..." requirement is not necessary. change the requirement to optional if BAT/TACK/STACK are sent to respond to a PPDU containing TWT information frame Reject – the existing text already covers the suggested. First, if, in response to the receipt of the frame soliciting a response that contains a Next TWT value, the responding STA happens to send a BAT or TACK or STACK, then in that case, the condition that follows is immediately satisfied, that is: “If a TWT requesting STA has transmitted a frame soliciting a response that contains a Next TWT value and the
8485 Alfred 297.03 9.44.1 "the TWT requesting STA shall be in the awake state following each TWT start time associated with each TWT agreement for at least the time associated with that TWT agreement even if no PS-Poll frame or U-APSD trigger frame has been transmitted by the STA." The STA can certainly go to sleep if a frame with EOSP = 1 is sent even before the TWT SP ends. Clarify that baseline PS switching mode still applies within the TWT SP. Revise – Tgah editor to execute changes shown in 11-16/0063r0 found under all headings that include CID 8485 which effectively agree with the commenter but also apply the change to another location that needed it. Discussion: None. Proposed changes TGah editor: the baseline text for these changes is Draft P802.11ah_D5.1.pdf CID 8466 9.44.6 NDP Paging Setup TGah editor: change the nth paragraph and (n+1)th paragraph of 9.44.6 NDP Paging Setup as shown: If the NDP Paging requester STA is a non-AP STA, it shall send a (NDP) PS-Poll frame or uplink trigger frame addressed to the NDP Paging responder, after SIFS. If the NDP Paging requester STA is an AP, it shall send an NDP CTS frame to self with the duration field equal to zero.
