Cover Story: Fifth-generation mobile communication systems (5G) have to accommodate both Ultra-Reliable Low-Latency Communication (URLLC) and enhanced Mobile Broadband (eMBB) services. While eMBB applications support high data rates, URLLC services aim to guarantee low latency and high reliability. eMBB and URLLC services are scheduled on the same frequency band, where their different latency requirements render their coexistence challenging. In this survey, we review coding schemes that simultaneously accommodate URLLC and eMBB transmissions and show that they outperform traditional scheduling approaches. Various communication scenarios are considered, including point-to-point channels, broadcast channels, interference networks, cellular models, and C-RANs. View this paper
