Abstract
Dynamically associating distributed mobile users with proper base stations in 6G heterogeneous networks (HetNets) becomes critical to achieve both diverse quality of service (QoS) requirements of all users and entire network performance. However, the significantly increased complexity of matching the irregularly distributed users and base stations as well as highly dynamic network traffic often cause unbalanced spatial-temporal loads for multi-tier base stations during user association. To overcome this challenge, we propose a new virtual network topology-based digital twin to reduce the complexity of load-balanced user association in 6G HetNets. During the digital twin construction stage, instead of using highly dynamic low-level physical layer attributes (e.g., channel conditions and SINR), we intentionally consider more stable and relevant communication performance indicators and physical statistics to effectively reflect both real-time link quality and overall network dynamics. To assist overall network operation, fast update of the digital twin for HetNets is achieved by adopting principal component analysis to discover specific network areas with changes. To improve the overall QoS provisioning and network performance, the proposed virtual topology-based digital twin is further utilized to predict the spatial-temporal dynamics of HetNets for more balanced user association by bipartite graph matching. Simulation results show that the proposed method can construct effective digital twins and support load-balanced user association with maximized network-wide QoS satisfaction.

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
