Abstract

fetched live from OpenAlex

Downloading remote files (e.g., pictures, videos) from online social networks via smart user equipments (UEs) (e.g., smartphones, tablets) is becoming popular. Friends who are nearby may want to download the same files shared by their mutual acquaintance. People can obtain these files in a device-to-device (D2D) manner via opportunistic connections to reduce their payment for data service. This is referred to as D2D data offloading. However, D2D communications on unlicensed spectrum using Bluetooth or WiFi-Direct may not maintain high data rate when many D2D pairs nearby need to communicate simultaneously. Since D2D connections are transient, it is important to improve spatial reuse of communication resources and increase the data rate of opportunistic D2D communications. In this paper, we propose a scheme to reuse the downlink licensed spectrum of cellular networks for D2D data offloading. Our proposed scheme includes determining the availability of digital files on neighbouring devices, estimating the channel gains, and performing channel allocation and power control for D2D pairs. Simulation results show that our proposed scheme does not affect the existing cellular UEs and it can also offload more data traffic when compared with WiFi-Direct on an unlicensed spectrum.

Teacher imitation

Not 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.
