Technical Summary

   The present document updates the SCHC (Static Context Header
   Compression and fragmentation) protocol RFC8724.  It defines a SCHC
   Compound ACK message format and procedure, which are intended to
   reduce the number of response transmissions (i.e., SCHC ACKs) in the
   ACK-on-Error mode, by accumulating bitmaps of several windows in a
   single SCHC message (i.e., the SCHC Compound ACK).

   Both message format and procedure are generic, so they can be used,
   for instance, by any of the four Low Power Wide Area Networks
   (LPWANs) technologies defined in RFC8376, being Sigfox, LoRaWAN, NB-
   IoT and IEEE 802.15.4w.

Working Group Summary

There was a broad consensus in the WG about the document. All remarks and
potential issues were treated with respect, discussed openly and addressed.

No controversies, no rough points.

Document Quality

There were two last call directorate reviews (SEC & OPS) and the comments were addressed by the authors.
