AI Technical Summary
Technical Problem
Packet duplication at the PDCP sublayer in New Radio Access Technology (NR) leads to inefficiencies in RLC operation and radio link failure, particularly in AM mode, due to handling of duplicates across multiple carriers.
Method used
Implement novel PDCP operations to inform RLC of duplicate SDUs and prevent RLF triggering by discarding or ignoring duplicates, and ensuring successful delivery is confirmed before transmitting further duplicates, even if retransmissions reach a threshold.
Benefits of technology
Enhances radio link control and reduces resource wastage by preventing unnecessary retransmissions and RLFs, optimizing communication efficiency in multi-connectivity scenarios.
