A 3GPP Perspective on Spectrum Sharing for 5G-to-6G Migration: From LTE-NR DSS Lessons to MRSS Design
arXiv:2604.26853v2 Announce Type: replace Abstract: Dynamic spectrum sharing (DSS) played an important role in the 4G-to-5G transition by allowing 5G new radio (NR) to reuse legacy spectrum without immediate static refarming. Yet practical deployments also exposed the cost of coexistence of NR with long-term evolution (LTE), including overheads, control-channel bottlenecks, neighbor-cell interference, etc. As 6G begins to take shape, spectrum scarcity below 7 GHz is again making 5G-6G...
Serverless5GC: Private 5G Core Deployment via a Procedure-as-a-Function Architecture
arXiv:2603.27618v2 Announce Type: replace Abstract: Open-source 5G core implementations deploy network functions as always-on processes that consume resources even when idle. This inefficiency is most problematic in private and edge deployments with sporadic traffic. Serverless5GC is an architecture that maps each 3GPP control-plane procedure to an independent Function-as-a-Service invocation, allowing scale-to-zero operation without modifying the standard N2 interface.
Toward Mobile and Converged Backhaul: The Promise of Wireless Access and Backhaul
arXiv:2606.06075v1 Announce Type: new Abstract: Wireless Access and Backhaul (WAB) is emerging as a key enabler for flexible and cost-efficient 5G deployments, offering a modular architecture that decouples access and backhaul while supporting multi-technology and mobile backhaul links. This article introduces the WAB framework standardized in 3GPP Release 19, outlining its architecture and operational principles. A practical implementation built with commercial hardware and open-source...
AUGUSTE: Online-Learning dApp for Predictive URLLC Scheduling
Announce Type: new Abstract: Ultra Reliable and Low Latency Communications (URLLC) was one of the main motivations behind 5G, with 3GPP advertising 1-10 ms latency targets for applications such as industrial automation, Vehicle-To-Everything (V2X), tactical edge networking, and unmanned-system control. Years on, real 5G Time Division Duplexing (TDD) networks still show median Uplink (UL) round-trip times in the 50-70 ms range, largely because of the Scheduling Request (SR) procedure that a...
Don’t repeat 5G mistakes with 6G, plead mobile operators
A body that represents mobile operators wants the migration to 6G networks to be as smooth as possible, learning lessons from the fractious 5G introduction that has left countries like the UK with a less than satisfactory service. The Next Generation Mobile Networks Alliance (NGMN) says that 6G requires a different standardization approach in order to prevent complexity and market confusion, alongside a smooth and cost-effective migration path for its members. What exactly defines 6G is...
COSMO: O-RAN-Based Service Management and Orchestration for Cross-Technology Multi-Tenant Radio Access Networks
arXiv:2606.05012v1 Announce Type: new Abstract: The evolution toward 6G networks envisions a heterogeneous Radio Access Network (RAN) comprising diverse access technologies, such as private 5G, public 4G/5G, and Wi-Fi, managed by multiple stakeholders. While considerable research effort has been devoted to O-RAN-based frameworks enabling rApp and xApp implementation and validation, few works provide integrated support for cross-technology RAN orchestration, end-to-end multi-tenancy, and a...
Flexible FTN-Aided OTFS Modulation for High-Mobility LEO Satellite-to-Ground Communications
arXiv:2601.22526v2 Announce Type: replace Abstract: In low Earth orbit (LEO) satellite communications, the link quality fluctuates drastically during a satellite pass, exhibiting a wide dynamic range from the horizon to the zenith. Moreover, the high relative velocity induces severe Doppler shifts. While orthogonal time frequency space (OTFS) modulation effectively resolves the doubly-selective fading, its spectral efficiency is fundamentally bounded by the Nyquist limit.
ReFLEX: Length-Generalizable CSI Denoising for MIMO-OFDM via Relative-Frequency Bias
arXiv:2606.00263v1 Announce Type: cross Abstract: This letter studies CSI denoising for MIMO--OFDM with variable NR resource block (RB) allocations. ReFLEX is a length-generalizable Transformer whose frequency attention uses a relative-frequency position bias (RFPB) generated from subcarrier offsets. A single checkpoint handles unseen RB lengths and can be applied to sparse DM-RS observations in the tested RB5/
ORIX: Orchestration of RIS with xApps for Smart Wireless Factory Environments
Announce Type: replace-cross Abstract: The vision of a smart wireless factory (SWF) demands highly flexible, low-latency, and reliable connectivity that goes beyond conventional wireless solutions. Reconfigurable intelligent surface (RIS)-empowered communications, when integrated with the open radio access network (O-RAN) architectures, have emerged as a promising enabler to meet these challenging requirements. This article introduces the methodology for the orchestration of RIS with xApps...
XAI-on-RAN: Explainable, AI-native, and GPU-Accelerated RAN Towards 6G
Announce Type: cross Abstract: Artificial intelligence (AI)-native radio access networks (RANs) will serve vertical industries with stringent requirements: smart grids, autonomous vehicles, remote healthcare, industrial automation, etc. To achieve these requirements, modern 5G/6G design increasingly leverage AI for network optimization, but the opacity of AI decisions poses risks in mission-critical domains. These use cases are often delivered via non-public networks (NPNs) or dedicated...
