摘要：
A wireless device and a method for controlling Discontinuous Reception (DRX) in the wireless device. The wireless device is capable of cellular and Device to Device (D2D) communication. The method comprises: in response to receiving a first uplink cellular communication grant, activating, for a first period of time (t1), a DRX-wake state for a cellular DRX configuration during which DRX-wake state the wireless device is configured to receive a second uplink cellular communication grant, and in response to receiving a first D2D communication grant, activating, for a second period of time (t2), the DRX-wake state for a D2D DRX configuration, wherein the D2D DRX configuration is separate from the cellular DRX configuration, and during which DRX-wake state the wireless device is configured to receive a second D2D communication grant. Thereby the wireless device is capable of controlling DRX using both the cellular DRX configuration and the D2D DRX configuration.
