Performance Comparison of Practical Resource Allocation Schemes for Device-to-Device Communications

<div>An example of a D2D transmission with resource reuse. The D2D Tx node communicates directly with the D2D Rx node sharing a PRB with the cellular user UE. The shared PRB is selected in a way that minimizes an estimate of the intracell interference that D2D communication might perceive (related to the gain <svg height="11.8631pt" id="M123"
