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.

Novel Scenarios for the Wireless Internet of Things (Dagstuhl Seminar 23222)

Authors: Haitham Hassanieh, Kyle Jamieson, Luca Mottola, Longfei Shangguan, Xia Zhou, and Marco Zimmerling

Published in: Dagstuhl Reports, Volume 13, Issue 5 (2023)

Abstract

The Internet of Things (IoT) aims to network everything near and far in our ambient environment. Although the functional innovations for IoT are going full steam ahead, newly-emerging scenarios such as the Internet of Ocean and Implantable Things often come with limited power budgets, challenging deployment scenarios, and demanding computational resources, which fundamentally stress conventional IoT architecture, communications primitives, and sensing capabilities. The goal of this Dagstuhl Seminar was to bring together researchers from both academia and industry globally to i) review the capacity of existing IoT research from radical perspectives; ii) summarize fundamental challenges in modern IoT application scenarios that may then be investigated in joint research projects; and iii) discuss new types of hardware architecture, network stack, and communication primitives for these emerging IoT scenarios.
