Abstract
Device-to-Device (D2D) cluster communication underlaying cellular networks has been proposed as a means of increasing the resource utilization, and improving the spectral efficiency. However, when D2D links cannot satisfy the connection requirements, in order to keep the connection, D2D communication has to switch back to cellular communication. Consider that the previous switching methods mainly concentrated on the network centralized controlled D2D communications, so we propose a novel switching solution aided by a cluster head for (semi-) distributed controlled D2D communications. We propose the switched D2D user itself search and access the target base station. The cluster head determines transmission mode based on the channel state information after switching. The numerical simulation demonstrates the hybrid mode outperforms the D2D mode in some conditions.
