Abstract:

Relay has been a promising technique for extending the coverage area of a cellular network without incurring additional cost for wired backhaul. With this merit, relay technology has been widely considered for developing and deploying cellular networks such as IEEE 802.16j WiMAX and 3GPP LTE-Advanced. As a natural consequence, standardization for relay support is now being conducted in the 3GPP 5G NR work item called Integration of Access and Backhaul (IAB) in Rel-16, which enables cost-effective deployment of small cells through wireless backhauling. In Rel-16 IAB, however, only fixed relays are considered. In order to meet diverse 5G requirements under various deployment scenarios, mobile relays can be useful to provide enhanced user experience to the onboard passengers in, for example, trains and buses. Hence, in this column, focusing on realistic 5G high-mobility deployment scenarios, we provide a brief background and motivation for mobile relay and investigate potential technical challenges to be overcome in the future 5G releases.
