## Minutes

[16:06] Admin
* Agenda: no comment
* coap-static-context
* schc-over-lorawan: republished as Proposed Standard
* Last call started - if all goes well we can expect publication in a month
* schc-over-nbiot: uses 3GPPP terminology, may need to be changed if IETF insists on using IETF terminology.
  - Pascal believes change is needed, because of review process in IETF. Kind of reviewers, and fair to other SCHC drafts.
  - Eric: this is an IETF document.
* yang data model: work to be resumed.
* lpwan command registry: we'll let it expire for the moment.

[16:14] SCHC Over PPP            (Pascal)  [15min]
* migrated to IntArea.
* wants padding between residue and uncompressed payload.
  - could make RuleId variable-length. Dismissed.
  - encode 0-6 padding bits in RuleId.
  - Julien: would have like to have padding between compression residue and payload, as well. Was not 8724-compliant.
* this padding issue to be discussed on the mailing list.
      
[16:21] SCHC Over LoRaWAN    (Olivier)              [10min]
* Process Eric Vyncke comments and published a new draft
* republished under Standard Track.
* Comments received from Rahul (IoT directorate). Will implement changes.


[16:25] AOB 
* IETF109: what does the audience want? meeting, or live with interims?
  - Alex: IETF meeting is a good milestone
  - Pascal: but timezone is going to be a problem for most LPWAN attendees. Why meet in the middle of the night if we an have interims at easier time
  - Eric: not such a pb for Europe. However, very early in the night for American East Coast.
  - JCZ: would be quite a challenge
  - Alex: could also be an opportunity to get attendees from Asia?
  - Pascal: have a look at past (physical) LPWAN meetings attendees list
* Eric: IETF110 will likely be online as well. Hotel cancellation needs to go out in the next few days.
* Pascal: will continue this discussion on the ML
* JCZ: is it really not possible to have meetings in our timezone?
* Alex: at last IETF, no parallel meetings allowed the IETF week or the week before.
