// Extends LTE MAC functionalities at the eNodeB side to support device-to-device (D2D)
// communications. Specifically, it enhances resource allocation procedures to enable direct
// communication between User Equipments (UEs), i.e., it allocates resources for D2D transmissions.
// Network-assisted D2D is only implemented (out-of-coverage D2D is not supported).
