The IESG has received a request from the IPv6 over Low Power Wide-Area
Networks WG (lpwan) to consider the following document: - 'LPWAN Static
Context Header Compression (SCHC) for CoAP'
<draft-ietf-lpwan-coap-static-context-hc-12.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2020-02-20. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract

This draft defines the way SCHC header compression can be applied to
CoAP headers. The CoAP header structure differs from IPv6 and UDP
protocols since CoAP uses a flexible header with a variable number of
options, themselves of variable length. The CoAP protocol messages
format is asymmetric: the request messages have a header format
different from the one in the response messages. This document
explains how to use the SCHC compression mechanism for CoAP.
