Abstract:
An apparatus and method that allow user equipment (UE) to transmit information directly with other user equipment, using a device-to-device (D2D) mode is disclosed herein. A first D2D UE (dUE1) that wishes so communicate to a second D2D UE (dUE2) in D2D mode makes various communications requests to an Evolved Node B (eNB), which can facilitate the connection between the dUE1 and the dUE2. Among these requests are to make the D2D connection via WiFi instead of via Long Term Evolution (LTE). The eNB determines the WiFi capabilities of dUE1 and dUE2, then assigns a subset of available channels to be scanned by dUE1 and a separate subset of available channels to be scanned by dUE2. Thereafter, the eNB can assign a WiFi channel based on the scans performed by dUE1 and dUE2.
