Managing O-RAN Networks: xApp Development From Zero to Hero [PDF]

IEEE Communications Surveys and Tutorials
The Open Radio Access Network (O-RAN) Alliance proposes an open architecture that disaggregates the RAN and supports executing custom control logic in near-real time from third-party applications, the xApps. Despite O-RAN's efforts, the creation of xApps remains a complex and time-consuming endeavor, aggravated by the sometimes fragmented, outdated, or

FlexApp: Flexible and Low-Latency xApp Framework for RAN Intelligent Controller

ICC 2023 - IEEE International Conference on Communications, 2023
RAN openness is a vision for 5G and beyond to avoid unnecessary lock-in effects. In this regard, the O-RAN alliance provides a new architecture with RAN intelligent controller (RIC) for both non-real-time and near-real-time cases, together with running applications, i.e., rApps and xApps. However, two key challenges remain in the current xApp framework:

Neural-Driven Control of RIS in 6G Networks: A GoSimRIS and xApp-Based Framework

IEEE Networking Letters
In this letter, we propose an O-RAN-based framework for Reconfigurable Intelligent Surfaces (RIS) control in 6G. The key objective is to enable the development of RIS control algorithms as xApps running at the Real-time Intelligent Controller (RIC) of Open RAN (O-RAN).

Securing 5G OpenRAN with a Scalable Authorization Framework for xApps

IEEE INFOCOM 2023 - IEEE Conference on Computer Communications, 2023
The ongoing transformation of mobile networks from proprietary physical network boxes to virtualized functions and deployment models has led to more scalable and flexible network architectures capable of adapting to specific use cases. As an enabler of this movement, the OpenRAN initiative promotes standardization allowing for a vendor-neutral radio ...

A unified service‐based capability exposure framework for closed‐loop network automation

Transactions on Emerging Telecommunications Technologies, Volume 33, Issue 11, November 2022., 2022
In this article, we motivate the need for an enhanced network exposure functionality for network automation. We motivate it by revising the state of the art, propose a candidate architecture, and proof its feasibility with a real world testbed.
