Abstract
In this paper, we introduce a virtualized device-centric radio access architecture for future fifth-generation (5G) mobile networks. Radio access networks (RAN)s have traditionally relied on Voronoi tessellations of cells, created by a careful deployment of access nodes, to enable spatial frequency reuse over those cells. With the trend firmly set to decouple the control- and user-planes for next-generation 5G mobile networks, we foresee radio access technology breaking away from the concept of cells and embracing a virtualized device-centric architecture. The aim for this paradigm shift is to meet the stringent quality of service (QoS) requirements of densely populated networks irrespective of users' physical proximity to the access nodes. Focusing on downlink user-plane (U-plane) virtualization, this paper proposes a device-centric hyper-transceiver (HT) design that capitalizes on group-to-group (G2G) communications between virtual multipoint transmission and reception nodes and proactively optimizes both sets of virtual nodes via dynamic point selection (DPS) enabled by cloud-RAN (CRAN) architecture and semi-static network-assisted receiver cooperation enabled by device-to-device (D2D) short-range communications, respectively. Using a full-fledged event-based system level simulator compliant with the 3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> generation partnership project (3GPP) long-term evolution advanced (LTE-Adv) specifications, our results show that the proposed virtualized U-plane architecture provides more than 50% average throughput and 200% coverage gains over LTE-A Release 11 baseline under some typical simulation scenarios.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
