Investigation of Interference Management Mechanism for D2D Communication in Licensed Band Spectrum

Device to device communication in licensed band 5G cellular network introduces interference to the existing cellular users which are communicating through eNodeB. Intracell and Intercell interference limits D2D communication in uplink and downlink. This article investigates an orthogonal precoding based mode selection and resource allocation technique which provides better solution for interference cancellation while allocating same spectrum among multiple D2D user and cellular user during uplink and down link communication. Simulation result has been shown for intracellular scenario which provides better result than traditional precoding method.
