Fronthaul Compression Control for Shared Fronthaul Access Networks

There is a widely held belief that future radio access network architectures will be characterized by increased levels of virtualization, whereby base station functionalities, traditionally residing at single location, scattered across different logical entities while being interfaced via high-speed fronthaul (FH) links. For the deployment such FH links, operators are faced with challenge maintaining acceptable performance same time keeping costs low. A common practice to exploit statistical multiplexing allowing several cells utilize link. As result, in order cope resulting aggregated traffic, techniques can used reduce required data rates. Herein, we focus on compression control strategies for multiple-ceilimuitiple-user scenarios sharing We propose various methods sounding reference signal (SRS) handling, and analyze FH-aware modulation scheduling strategies. Considering full system setup, including networks, numerical evaluation conducted using 5G NR system-level simulator implemented ns-3. Simulation results show under stringent capacity constraints, optimized provide significant user-perceived throughput gains over baseline (between 5.2 × 6.9 ×). On top them, SRS handling achieve additional 2 41 percent gains.
