In this article, scheduling method of in-band Device-to-Device (D2D) communication underlaying cellular networks is studied. We address a single cell scenario in which several UEs have buffered data for local UEs in the same cell, and they are considered as potential D2D pairs. We propose an interference coordinated scheme, in which eNB selects D2D or ULiDL mode for each potential D2D pair, and allocates...
In this article ad-hoc communications underlying cellular networks is studied. Two branches of usage cases, which lead to two modes of operation, are analyzed. We propose a coordinated in-band scheme where the ad-hoc communication uses the same licensed band operating the cellular networks and is under the control of cellular network operators. We show that the interference resulting from in-band...
Well-aligned crystalline ZnO nanorod arrays were synthesized via an aqueous solution route with ammonia and zinc nitrate as inorganic precursors. ZnO crystalline seed films were firstly coated on ITO substrates for epitaxial growth of rods through sol–gel processing and heat treatment. SEM, TEM, SAED and XRD were utilized to characterize morphologies and structures of ZnO crystals. Heterogeneous nucleation...
