Abstract
Method, apparatus and system for D2D communication are provided. The method includes: a first user equipment receives configuration message(s) from a network, wherein the configuration information about D2D discovery signal(s) is carried in the configuration message(s); the first user equipment detects D2D discovery signal(s) from a second user equipment according to the configuration information carried in the configuration message(s); the first user equipment transmits a request message to the network according to the result of the detection to acquire the identity of the second user equipment transmitting the detected D2D discovery signal; and the first user equipment receives a response message returned from the network, wherein the identity of the second user equipment or rejection information indicating the rejection to the discovery of the second user equipment by the first user equipment is carried in the response message. The present disclosure addresses the problem of the peer discovery of D2D incorporated in a cellular communication system.
