1. An apparatus comprising:
at least one processor configured to cause a New Radio (NR) node to:
generate a first data message;
initiate transmission of the first data message to a second node; and
process a second message from the second node, wherein a bit in an initial octet of the second message indicates the existence of a highest successfully delivered packet data convergence protocol (PDCP) protocol data unit (PDU) sequence number (SN) in the second message, and when the bit is set to ‘1’, said processing includes processing the highest successfully delivered PDCP PDU SN in the second message.
