METHOD, APPARATUS AND SYSTEM FOR D2D COMMUNICATION
First Claim
1. A apparatus for Device-to-Device (D2D) communication, the apparatus located in a first user equipment, comprising:
- a first receiving module, configured to receive configuration message(s) from network, wherein configuration information about D2D discovery signal(s) is carried in the configuration message(s);
a detection module, configured to detect D2D discovery signal(s) from a second user equipment according to the configuration information carried in the configuration message(s);
a transmitting module, configured to transmit a request message to the network according to the detection of the detection module, wherein the request message is used to acquire the identity of the second user equipment transmitting the detected D2D discovery signal(s); and
a second receiving module, configured to receive a response message sent 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.
