Abstract: Systems and methods of providing feedback when a specific PDU is successfully delivered or transmitted are described. The node hosting PDCP entity indicates triggering of a DDDS frame from the remote corresponding node. Rather than immediately triggering transmission of a DDDS frame, the node hosting PDCP entity indicates triggering based on successful delivery of a PDU having a specific SN, as long as in-sequence delivery or transmission of PDUs up to the specific SN was successful. The DDDS frame is transmitted once the corresponding node determines that the PDU having the SN was successfully delivered or transmitted. After reporting by the DDDS frame, the QoS flow associated with the PDUs is remapped from a source DRB to a target DRB.

Abstract: Technology for a user equipment (UE), operable to generate an enhanced buffer status report (eBSR) is disclosed. The UE can identify packets for uplink transmission. The UE can filter the packets for uplink transmission, to identify a number of small packets pending for transmission and a number of larger packets, relative to the small packets, that are pending for transmission in the uplink transmission. The UE can encode the eBSR for transmission to a next generation node B (gNB), wherein the eBSR includes information identifying the number of small packets pending for transmission. The UE can have a memory interface configured to send to a memory the number of small packets pending for transmission.

Abstract: Disclosed are methods, systems, apparatus, and computer programs for compressing an Ethernet packet. In one aspect, a method involves mapping a portion of the Ethernet packet to a connection identity to compress the Ethernet packet. Additionally, the method involves encoding, in a user plane protocol stack layer, the connection identity in a data structure for transmission.

Abstract: An apparatus of a cellular data communication device includes one or more memory devices configured to store data corresponding to a plurality of service data units (SDUs) from a protocol layer higher than a packet data convergence protocol (PDCP) layer of a cellular data network, and one or more processors operably coupled to the one or more memory devices and configured to concatenate the plurality of SDUs into a single protocol data unit (PDU) above the PDCP layer.
