Abstract:
A bandwidth efficient way to improve reliability without introducing additional latency is provided for Ultra-Reliable and Low Latency Communications (URLLC) service in 5G NR. In particular, using rateless fountain codes in conjunction with packet duplication for split bearers at the Packet Data Convergence Protocol (PDCP) layer increases the reliability of transmission without the need for retransmissions, and with a lower bandwidth requirement compared to traditional packet duplication.
