A two-hop link transmission method and apparatus are provided. The method includes establishing a two-hop link and scheduling transmission on the two-hop link in a Device-To-Device (D2D) communication network. The two-hop link transmission method includes identifying neighbor terminals available for communication with the transmission terminal, selecting one of the neighboring terminals as a recipient terminal, determining a type of a link to be established with the selected neighboring terminal between a single-hop link and two-hop link types, selecting, when the two-hop link type is determined, a relay terminal among the neighboring terminals, establishing the two-hop link with the recipient terminal via the relay terminal, allocating a Multi-Hop Connection Identifier (MCID) for the two-hop link, and transmitting data to the recipient terminal through the two hop link.
