1. An apparatus, comprising:
a memory; and
processing circuitry in communication with the memory and arranged to:
receive a Downlink (DL) User Data Frame from an other node hosting a New Radio (NR) Packet Data Convergence Control (PDCP) entity, wherein the DL User Data Frame includes a DL report NR PDCP protocol data unit (PDU) sequence number (SN) parameter in the DL User Data Frame, wherein the DL report NR PDCP PDU SN indicates that the other node requests providing a down link delivery status report based on a NR PDCP PDU with the DL report NR PDCP PDU SN; and
when the NR PDCP PDU with the DL report NR PDCP PDU SN is successfully delivered to a UE, generate, for transmission to the other node, a DL Data Delivery Status (DDDS) frame that indicates the successful delivery.
