Mode Selection for Device-To-Device Communication Underlaying an LTE-Advanced Network

TLDR

Device‑to‑Device communication underlaying a cellular network enables local services with limited interference, and a well‑performing mode selection is critical for its adoption. The study aims to determine the optimal resource‑sharing mode for Device‑to‑Device communication in a single cell and to extend this into a mode‑selection procedure for multi‑cell environments. The authors analyze resource‑sharing modes in a single cell and develop a mode‑selection procedure informed by those findings for deployment in multi‑cell scenarios. Evaluation shows that the proposed procedure yields more reliable Device‑to‑Device communication with limited interference to the cellular network than simpler mode‑selection procedures.

Abstract

Device-to-Device communication underlaying a cellular network enables local services with limited interference to the cellular network. In this paper we study the optimal selection of possible resource sharing modes with the cellular network in a single cell. Based on the learning from the single cell studies we propose a mode selection procedure for a multi-cell environment. Our evaluation results of the proposed procedure show that it enables a much more reliable device-to-device communication with limited interference to the cellular network compared to simpler mode selection procedures. A well performing and practical mode selection is critical to enable the adoption of underlay device-to-device communication in cellular networks.
