Abstract: Disclosed is a method and apparatus for communication in a millimeter band communication system. In a case in which a first terminal obtains a list including members of a cooperative group in which terminals receive a service with the same beam as a first terminal's beam, the first terminal informs a second terminal, corresponding to a member of the list, of communication link failure when the failure occurs, and requests a cooperative service. After that, the first terminal receives information on the service from a base station through the second terminal.
