Better Together: Leveraging Multiple Digital Twins for Deployment Optimization of Airborne Base Stations

Airborne Base Stations (ABSs) allow for flexible geographical allocation of network resources with dynamically changing load as well as rapid deployment of alternate connectivity solutions during natural disasters. Since the radio infrastructure is carried by unmanned aerial vehicles (UAVs) with limited flight time, it is important to establish the best location for the ABS without exhaustive field trials.

CSI-Based User Positioning, Channel Charting, and Device Classification with an NVIDIA 5G Testbed

Channel-state information (CSI)-based sensing will play a key role in future cellular systems. However, no CSI dataset has been published from a real-world 5G NR system that facilitates the development and validation of suitable sensing algorithms. To close this gap, we publish three real-world wideband multiantenna multi-open RAN radio unit (O-RU) CSI datasets from the 5G NR uplink channel: an indoor lab/office room dataset, an outdoor campus courtyard dataset, and a device classification dataset with six commercial-off-the-shelf (COTS) user equipments (UEs).

AI-Native 6G: Empowering Intelligent RAN with Accelerated Compute

AI and communication is a key usage scenario envisaged for 6G. In contrast to 5G, where AI adoption has come only as an afterthought, 6G aims to embrace AI right from the beginning. AI-native RAN shifts the trend from fixed, one-size-fits-all algorithms to continuously adaptive, data-driven intelligence embedded throughout the RAN stack for site-specific optimizations. However, embedding AI for RAN introduces stringent latency constraints and computational challenges.

Gated DeltaNet-2: Decoupling Erase and Write in Linear Attention

Linear attention replaces the unbounded cache of softmax attention with a fixed-size recurrent state, reducing sequence mixing to linear time and decoding to constant memory. The hard part is not just what to forget, but how to edit this compressed memory without scrambling existing associations. Delta-rule models subtract the current read before writing a new value, and Kimi Delta Attention (KDA) sharpens forgetting with channel-wise decay.

Monitor refresh rate impacts FPS video gamers' perceptions of display ‘smoothness’ and target acquisition performance

Esports, particularly First-Person Shooter (FPS) games, rely heavily on one's ability to rapidly perceive and respond to visual targets, a skill known as target acquisition. Modern gaming monitors increasingly feature higher refresh rates (up to 360Hz). The current study examined whether FPS gamers can perceptually distinguish between different monitor refresh rates (60Hz, 144Hz, 360Hz) and whether these differences translate to performance improvements in target acquisition tasks. Gamers (N = 101) completed a custom FPS task across three refresh rate conditions.
