Packet data convergence protocol service data unit concatenation

A method for a user equipment (UE), the method comprising:

• identifying multiple packet data convergence protocol (PDCP) service data units (SDUs) to be sent to a network node;
• generating a concatenated PDCP packet data unit (PDU) comprising:
• the multiple PDCP SDUs;
• and
• a header comprising a sequence number (SN) of a first PDCP SDU of the multiple PDCP SDUs and a SN bitmap indicating SNs for additional PDCP SDUs in the concatenated PDCP PDU;
• and
• sending the concatenated PDCP PDU to a network node.

A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a network node, cause the network node to:

• receive a concatenated packet data convergence protocol (PDCP) packet data unit (PDU) comprising:
• multiple PDCP service data units (SDUs);
• and
• a header comprising a sequence number (SN) of a first PDCP SDU of the multiple PDCP SDUs and a SN bitmap indicating SNs for additional PDCP SDUs in the concatenated PDCP PDU;
• and
• demultiplex the multiple PDCP SDUs based on the header.
