Performance Isolation for 5G RAN Slices Across Multiple Interfering Cells

Authors: Taimoor Tariq, Yongzhou Chen, Haitham Hassanieh, and Radhika Mittal

Published in: OASIcs, Volume 139, 1st New Ideas in Networked Systems (NINeS 2026)

Abstract
Radio Access Network (RAN) slicing, a key 5G feature, enables different slices (i.e. tenants or applications) to share the same physical network infrastructure while pursuing diverse objectives such as fairness, prioritization, or maximizing throughput. Each slice is allocated a share of radio resource blocks (RBs), which it further schedules among its users as per its own performance objective. In this paper, we identify the unique challenges that arise when performing RAN slicing in today’s multi-cell deployments that require a mechanism for managing interference among cells. We highlight how interference management decisions, that can be easily made in the absence of slicing (where all users share a common objective set by the network operator), become challenging with 5G slicing where we must respect the individual objectives of multiple slices, while retaining performance isolation across slices. We present a system, RadioNinja, that tackles this challenge through a unique decision-making framework that allows different slices to independently contribute towards interference management decisions. RadioNinja further employs a series of techniques to make such decisions within tight RAN scheduling budget of hundreds of microseconds. Trace-driven simulations with real-world channel measurements show that RadioNinja improves slice-level objectives (e.g., throughput, fairness, flow completion times) by 20–60% over state-of-the-art baselines, while consistently meeting sub-millisecond decision deadlines.

Towards an Integrated Development Environment for Context-Aware User Interfaces

Authors: Tim Clerckx and Karin Coninx

Published in: Dagstuhl Seminar Proceedings, Volume 5181, Mobile Computing and Ambient Intelligence: The Challenge of Multimedia (2005)

Abstract
The emergence of mobile computing devices brings along the fact that users interact with computers in various environments. The user interface of a mobile system can be affected by environmental context. Several approaches succeed in providing architectures and frameworks to support the building and reuse of software components considering context information. Taking into account context information in designing the interaction of a system, however, has not yet been extensively investigated. In this paper we will discuss an Integrated Development Environment, DynaMo-AID, we are developing to support the design, prototyping, evaluation and deployment of context-aware interactive systems.
