E2 Service Models in O-RAN: A Specification-Grounded Tutorial and Implementation Analysis

IEEE Access
The E2 interface and its associated E2 Service Models (E2SMs) are the primary mechanisms through which the Near-Real-Time RAN Intelligent Controller (Near-RT RIC) observes and controls Radio Access Network (RAN) behavior in O-RAN.

xApp Conflict Mitigation with Scheduler

Open RAN (O-RAN) fosters multi-vendor interoperability and data-driven control but simultaneously introduces the challenge of coordinating pre-trained xApps that may produce conflicting actions. Although O-RAN specifications mandate offline training and validation to prevent the deployment of untrained or inadequately tested models, operational ...

Detection and mitigation of indirect conflicts between xApps in Open Radio Access Networks

IEEE INFOCOM 2023 - IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2023
In Open Radio Access Networks, the Conflict Mitigation component, which is part of the Near-RT RIC, aims to detect and resolve any conflicts between xApp decisions. In this paper, we propose a universal method for detecting and resolving of indirect conflicts between xApps. Its efficiency is validated by extensive computer simulations.
