Abstract

In this paper, the principles and performance of 5G new radio (NR) based ultra-reliable low-latency communications (URLLC) building on subband filtered cyclic-prefix orthogonal frequency-division-multiplexing (CP-OFDM) are provided and analyzed. We will demonstrate that subband filtered URLLC allows to achieve highly reliable link performance, which is not affected by interference induced by a mobile broadband service using a different numerology. In addition, we analyze and demonstrate asynchronous URLLC uplink performance with relaxed power control requirements to show that significant receiving power differences in the 5G NR base station (gNB) receiver can be tolerated, especially if highly selective subband filtering is applied in both the URLLC devices transmitters and the gNB’s receiver. We also demonstrate how the mobile broadband users may be interfered by the URLLC users in mixed numerology scenario, unless sufficient guard bands and sophisticated waveform signal processing solutions improving spectral localization in transmitter and receiver side are applied. Overall, the results show that by using subband filtering on top of basic CP-OFDM processing, frequency multiplexing URLLC
and enhanced mobile broadband (eMBB) services within one 5G NR carrier is feasible.
