Relay communication method of communication ue and communication ue thereof

A method for operating a relay terminal, the method comprising:

• broadcasting a search message;
• receiving information for indicating at least one relay terminal of a plurality of relay terminals having transmitted search messages to the remote terminal;
• identifying a second relay terminal among the at least one relay terminal;
• and
• transmitting identification information for the identified second relay terminal to the remote terminal.

A remote terminal comprising:

• at least one transicever;
• and
• at least one processor operativley coupeld to the at least one transicever,
• wherein the at least one processor is configured to:
• receive a plurality of search messages from a plurality of relay terminals;
• identify at least one relay terminal among the plurality of relay terminals based on the received search messages;
• transmit information for indicating the identified at least one relay terminal to a first relay terminal of the plurality of relay terminals;
• receive identification information for a second relay terminal from the first relay terminal;
• and
• perform relay communication with the second relay terminal.
