An important ingredient of the future 5G systems will be Ultra-ReliableLow-Latency Communication (URLLC). A way to offer URLLC without intervention inthe baseband/PHY layer design is to use \emph{interface diversity} andintegrate multiple communication interfaces, each interface based on adifferent technology. Our approach is to use coding to seamlessly distributecoded payload and redundancy data across multiple available communicationinterfaces. We formulate an optimization problem to find the payload allocationweights that maximize the reliability at specific target latency values. Byconsidering different scenarios, we find that optimized strategies cansignificantly outperform $k$-out-of-$n$ strategies, where the latter do notaccount for the characteristics of the different interfaces. Our approach issupported by experimental results.
