a sending unit configured to send a dedicated discovery signal;
a receiving unit configured to receive a response message, wherein the response message is sent by a second user equipment
that has detected the dedicated discovery signal;

a connection establishment unit configured to establish a device-to-device connection with the second user equipment after
receiving the response message; and

a communication unit configured to communicate with a network side through the device-to-device connection and a cellular
communication link between the second user equipment and the network side;

wherein the dedicated discovery signal is a signal occupying one or more than one resource element, and has specific sending
time and/or frequency location, and wherein the dedicated discovery signal is a data block carrying a synchronization signal
or preamble, and the data block has an appointed modulation and coding scheme.
