摘要： A method of operating a first wireless communication device to perform D2D discovery includes obtaining multiple discovery message detection results, and determining a D2D discovery status of a second wireless communication device based on the multiple discovery message detection results. Using multiple discovery message detection results to determine the D2D discovery status of the second wireless communication device significantly increases the reliability of D2D discovery, thereby increasing the likelihood that a device available for D2D communication will be detected, while reducing the likelihood of false detections.

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.
