eAxC_ID Composer / Decomposer is an interactive tool for working with O-RAN fronthaul eAxC_IDs, where the 16-bit identifier is split into DU_Port_ID, BS_ID, CC_ID, and RU_Port_ID fields. Instead of hardcoding a fixed bit layout, the tool lets you define each field's bitmask yourself, so it adapts to any O-RAN eAxC_ID convention — including non-contiguous bit assignments — and flags overlaps or uncovered bits in real time on a live bit-grid. It supports two workflows: Construc

1. Introduction & Structural Background The transition from traditional monolithic Base Stations to disaggregated Open Radio Access Networks (O-RAN) has fundamentally reshaped the telecommunications industry. In a classic Distributed RAN (D-RAN), the baseband processing and RF frontends are tightly integrated using proprietary point-to-point protocols like the Common Public Radio Interface (CPRI). CPRI transmits continuous time-domain, uncompressed In-phase and Quadrature (IQ

1. Introduction Power control is one of the least visible but most influential mechanisms in cellular radio systems. In 5G NR, it directly impacts: Uplink throughput and latency Cell-edge user experience Inter-cell interference UE battery life Massive MIMO beam efficiency Network energy consumption (Green RAN goals) Unlike LTE, 5G NR operates with: Very wide bandwidths Beam-based transmission Dynamic TDD Cloud-native and O-RAN architectures As a result, power control in 5G NR

1. Introduction Modern 5G radio access networks have reached a level of complexity where traditional automation approaches are no longer sufficient. While machine learning has been widely adopted in telecom analytics, most deployed solutions still behave as passive systems: they ingest data, run inference, and output a score, label, or alert. In practice, experienced RAN engineers do not work this way. They observe symptoms, form hypotheses, validate those hypotheses by check

1. Introduction Radio Access Networks are becoming more software-driven, disaggregated, and automation-centric. To handle the complexity of dense deployments, Massive MIMO, spectrum fragmentation, and diverse traffic profiles, operators are moving toward intelligent control loops in the RAN.This is where O-RAN Alliance’s RAN Intelligent Controller (RIC) architecture—featuring rApps (non-real time, >1 second) and xApps (near-real time, 10 ms–1 s)—comes into play. These applica

O-DU ↔ O-RU Interoperability Troubleshooting (O-RAN WG4 C/U, S & M Planes) focuses on identifying and resolving functional and timing mismatches between the Distributed Unit (O-DU) and Radio Unit (O-RU) across the Open Fronthaul interface defined by O-RAN Working Group 4. It provides a systematic approach to diagnosing issues in the Control/User Plane (C/U), Synchronization Plane (S), and Management Plane (M)—the three pillars of inter-vendor interoperability. The guide emph
