title = "On Relay Selection for Relay-Assisted D2D Communications with Adaptive Modulation and Coding in Cellular Systems",
abstract = "Developing device-to-device (D2D) communications can improve spectrum efficiency and traffic offloading capability of cellular systems. But only considering direct D2D communication mode may limit these benefits brought in by D2D communications, for direct D2D mode may not be available due to the long separation distance and poor link quality. Hence, relay-assisted D2D communication is presented to expand the coverage of D2D communications. One of the key points in developing relay-assisted D2D communication is to find out the optimal relay user equipment (UE) to assist data transmission between the source and destination D2D-capable UEs. In this paper, a cross-layer relay selection scheme is researched, which considers the end-to-end data rate, end-to-end transmission delay, and remaining battery time of the relay-capable UEs. Specially, we propose a method to estimate the end-to-end transmission delay for the relay-involved D2D path when adaptive modulation and coding (AMC) is taken into account. Performances of the proposed scheme are also evaluated.",
