Abstract: Facilitation of a network assisted device-decided system can increase throughput of D2D devices and the link reliability of macrocells. In a network assisted device-decided system a macrocell can broadcast resource allocation data to D2D devices. The D2D devices can then select channels and adjust transmission power to offload traffic from the macrocell, thus creating a high spectrum efficiency with low power.

Abstract: A multi-functional hand tool includes a base, an upper cover, a cam, a turning disk, a plurality of tool heads, and an indication unit. The base and the upper cover have a plurality of tracks, respectively. The turning disk is pivotally connected at a lower side of the base. In the tracks at the base and the upper cover are tool heads having distinct styles, and the tool heads are accommodated by springs. A cam is additionally provided between the base and the upper cover. By rotating the turning disk, the cam is driven to push the tool heads and compress the springs, thereby stretching the distinct tool heads out of the tracks for further usage.
