Abstract
Dynamic spectrum sharing (DSS) enables base s-tations to share the time-frequency resources between different radio access technologies which can speed up the evolution from 4G to 5G. The current NR DSS standards have ignored the strong downlink interference from the neighbour cell cell-specific reference signal (CRS), which has been a barrier to the real deployment of DSS. Based on the 3GPP Rel-17 work item, this paper investigates multiple candidate CRS interference handling solutions as well as the potential Rel-17 standard impact. Perfect performance gain can be shown in the link-level simulation results.
