Abstract
A Device to Device (D2D) user equipment (UE) is configured to support synchronization in a D2D network. The D2D UE includes an antenna configured to communicate via a D2D communication. The D2D UE also includes processing circuitry configured to enter a communication Mode 2 when certain conditions are met. The certain conditions include: when a first timer (T) for detecting radio link failure is running, a second timer (T) for initiating the connection reestablishment is running, or a third timer (T) for requesting connection reestablishment is running. In communication Mode 2, the D2D UE, on its own, selects resources from resource pool(s) to transmit D2D data and D2D control information. The processing circuitry further configured to exit the communication Mode 2 and enter a communication Mode 1 when the certain condition is no longer met. In communication Mode 1, the D2D UE uses resources configured by another station.
