Abstract Abstract
The present document describes an extension to the SCHC (Static The present document describes an extension to the SCHC (Static
Header Compression and Fragmentation) protocol [RFC8724]. It defines Header Compression and Fragmentation) protocol [RFC8724]. It defines
a SCHC Compound ACK message format, which is intended to reduce the a SCHC Compound ACK message format, which is intended to reduce the
number of downlink transmissions (i.e., SCHC ACKs) by accumulating number of downlink transmissions (i.e., SCHC ACKs) by accumulating
bitmaps of several windows in a single SCHC message (i.e., the SCHC bitmaps of several windows in a single SCHC message (i.e., the SCHC
Compound ACK). Compound ACK).
