for the MAC and Frame Format comments (as
categorized in 15-10-0852-08)
• Already done (in November)
• “ready to go” to TG next week
– Includes comments covered by proposed resolutions
agreed to yesterday
• Not yet resolved, way forward identified for all
– Some resolutions proposed
– Some need discussion/work, suggest plan

Approved in Nov
• Accept
– 554: note in XLS says "A" but should be "AP“.
– 671: remove clause 5.5.3 from 4g draft.
• Accept in Principle:
– 105: Explanation given, no change.
– 490, 492, 493, 634: AP align frame formats with 4e draft.
– 329: "aNBPANSlotDuration" becomes "aBaseSlotDuration"
• Rejected:
– 413: Reject: Clarifies purpose of figures 22
– 684: Reject, refers to 15-10-0916-01-004g

Proposed Resolutions Ready
• PD-Data (categorized as MAC):
– CID #35,36,66, 427, 202, 203, 208, 540:
Comments on PD-Data parameters, resolved by
removing primitive.
– CID# 724: MCPS parameters inconsistent with PDData parameters: resolved by removing PD-Data.
– 202, 203 Removed primitives, all parameters

Proposed Resolutions Ready
MCPS-Data parameters: Per minutes from 13-Jan, we
agreed to resolution to comment #281 to remove
TxChannel, PPDUCoding and FCS length parameters
from MCPS-Data (table 77 and associated text), and to
add a new PIB attribute phyFSKFECenabled.
Also resolves (Accept in Principle):
• 281, 282: Fixed by removing TxChannel parameter.
• 282,, 725: fixed by removing PPDUCoding parameter.
• 726: fixed by removing FCSLength parameter
• 494: resolved by removing TxData parameter

Proposed Resolutions Ready
• Other
– 84: Comment resolved by the roll-up. Note: Refers
to 15-10-0872-06-004g, but the comment appears
to be on the parameters from the base standard.
Either way it is fixed in the roll-up. Suggest udate
10-0872r6 also to align with roll-up.

New Proposed Resolutions
(Easy)
• 469: Use correct ACK length in equn: comment is correct,
recommend Accept.
• 501: Frame format figures s/b consistent: recommend
ACCEPT.
• 280: Suggest this resolved between the MCPS-Data
comments and aligning with the roll-up. Recommend
Accept in Principle.
• 880: Repeating MAC text; Recommend Accept.
• 727,728: Mode switch parameters in MCPS-Data should
apply only to FSK? Recommend Accept in Principle; need
clarification text that mode switch initiated from FSK mode
only, but can switch to any PHY modes. Re-assign to mode
switch.

Work in progress/needs work
• 681 (also fits in delayed ACK but addresses more)
– Suggest work with delayed ACK and alignment with 4e
• How "time" is specified (the meaning of 'time'). Work in progress:
– 214,328,336,380,682, 739, 887, 920, 737
– Suggest engage WG TE to work on this w/appropriate technical input
– 737: Relates to how ‘symbols per octet’ is used to specify time
• Delayed Acknowledgement (needs work)
–
–
–
–
59, 470, 623, 681, 889
502: use 4e ACK formats.
suggests 4e enables implementing the same functionality by the NHL
Suggest Phil and Ben can sort it out

Misc. Stuff
• Resolution for 494 in XLS says ‘fixed by PDData” but that’s not right – use resolution
from here instead.
