Abstract

A technology for device to device (D2D) communication scheduling is disclosed. A D2D device can be synchronized with a base station of a cellular system. A sub-frame symbol boundary can be identified in the cellular system for the D2D communication. A resource for a D2D communication can be allocated from the D2D device to another D2D device within the sub-frame boundary of the cellular system. The D2D device can be switched to perform a D2D communication with another D2D device in proximity with the D2D device, wherein the other D2D device is substantially synchronized with the base station of the cellular system. The D2D device can communicate with the other D2D device within at least one symbol boundary time within the selected subframe.
