Abstract: An electronic device and a wireless communication method in a wireless communication system. The electronic device includes circuitry configured to: set configuration information for D2D communication measurement for a first UE served by the electronic device, wherein the configuration information contains reference signal information about a second UE of a candidate object with which the first UE conducts D2D communication; send the configuration information, to trigger communication link quality measurement between the first UE and the second UE; receive a measurement report from the first UE; determine whether to convert the communication between the first UE and a current communication object to a communication with the second UE based on the measurement report; and send conversion information when the conversion determination unit determines to convert the communication, to notify the first UE and the UE to conduct communication.
