Abstract

5G downlink Inter-Cell Interference Coordination (ICIC) has a twofold objective: to better exploit the benefits of ICIC in coherence with the rest of Radio Resource Management (RRM) principles in 5G; and to support new 5G service classes and their coexistence in a multi-service setting. We propose on-demand Power Boosting and Inter-cell Coordination (PB-IC) to meet high reliability and low latency requirements of critical data without compromising the spectral efficiency of the rest of traffic. PB-IC is demostrated to provide similar latency gains as the classical frequency reuse, but much lower impact to the enhanced Mobile BroadBand (eMBB) traffic. Results demonstrate that the tail of the latency distribution is reduced as much as 100% in the 10^-4 percentile, achieving comparable gains to static frequency reuse. At the same time, the degradation in eMBB throughput is minimized, reaching a 14% loss instead of the 50% observed with static ICIC. We discuss the standardization effort required for having PB-IC supported, with considerations of the measurement requirements to the UE and the infrastructure backhaul latencies.
