Abstract:
An apparatus and method of allowing user equipment (UE) to transmit information directly with other user equipment, using a device-to-device (D2D) mode is disclosed herein. A D2D UE (dUE1) that wishes so communicate to another UE (dUE2) in D2D mode makes various communications requests to an Evolved Node B (eNB), which can facilitate the connection between dUE1 and dUE2 by having the dUE1 measure the signals from dUE2 to help establish a D2D connection between the dUE1 and the dUE2.
