Name	Type	Description
LteMacEnbD2D	simple module	This module 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).
