Sliding Network Coding for URLLC

In this paper, we propose a network coding (NC) based approach to ultra-reliable low-latency communication (URLLC) over erasure channels. transmitting multiple data packets, demonstrate that the use of random NC can improve reliability in terms decoding error probability, while it incurs longer delay than well-known $K$ -repetition. To avoid long delay, consider sliding (SNC) design allows highly reliable transmission each packet with guaranteed delay. A few examples are derived and their rates analyzed. Through analysis, show rate SNC is much lower -repetition at same spectral efficiency, which means more be achieved using
