This paper considers high reliability transmission for anchored indoor New Radio Unlicensed (NR-U) systems, in which unlicensed spectrum with wideband operation is combined with other NR licensed spectrum as anchor. To achieve high reliable transmission using unlicensed spectrum, success transmission ensuring scheme is investigated for indoor NR-U deployment. By modeling of Success Transmission Probability (STP) with nonlinear Levenberg-Marquardt method, STP-based packet request algorithm and STP-based channel allocation algorithm are proposed for initial transmission and Automatic Repeat reQuest (ARQ) retransmission, respectively. Simulation results show that the proposed success transmission ensuring scheme significantly decreases retransmission ratio and further provides less transmission latency and higher throughput. In a word, this paper provides an effective solution which satisfies high reliable transmission requirement for NR-U.
