In-Band Coexistence of New Radio with Fixed Satellite Services in C-Band

This paper investigates solutions for seamless in-band coexistence of new radio (NR) network with fixed satellite services (FSS) broadcast network utilizing digital video broadcast-second generation (DVB-S2) technology in the C-band. The in-band coexistence is facilitated by the NR network’s adaptability across multiple resource allocation dimensions, including power control, time allocation, and spectral usage within the FSS band. We develop a comprehensive framework for analyzing co-channel interference at both the FSS and NR network receivers, considering their respective transmission and reception characteristics and parameters. We analyze the system performance of the FSS network in terms of Signal-to-Interference-plus-Noise Ratio (SINR). Extensive numerical simulation are conducted to illustrate the impact of system parameters on the in-band coexistence performance.
