摘要： A method performed by a central network node of instructing one of a first network node and a second network node to transmit to a first wireless device, wherein all operate in a combined cell deployment. The central network node receives a first Channel Quality Indicator, CQI, and a third CQI sent by the first wireless device. The first CQI has been computed by the first wireless device based on a first unique signal transmitted by the first network node. The third CQI has been computed by the first wireless device based on a second unique signal transmitted by the second network node. The central network node identifies the one of the first and the second network nodes having a better channel quality, based on the received first CQI and the third CQI. The central network node sends a first message to the identified network node, instructing it to transmit to the first wireless device.

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.
