Heterogeneous-Modulation NOMA-ARQ with RR-IIC for IoT Networks
This paper investigates non-orthogonal multiple access (NOMA) with stop-and-wait (SW) automatic repeat request (ARQ) for heterogeneous Internet of Things (IoT) networks with mixed modulation orders. In this system, two users with different service requirements share a NOMA-based backhaul link, where one user employs a...
