    Abstract: Disclosed is a method of using relay that may continuously transmit data without time division based on superposition coding in a communication system. When transmission of a relay-supported user signal via a base station-relay link is performed, the method of using relay based on the superposition coding reuses a resource allocated to a direct-transmission user based on the superposition coding to perform the transmission. According to example embodiments, a separate resource for the base station-relay link may not be needed, and continuous relay transmission is possible without time division, thereby substantially increasing frequency efficiency and reducing a transmission delay caused by the use of the relay.

    Abstract: A user authentication system using a personal identification number, includes a user terminal device for requesting issuance of a personal identification number from an authentication server, storing and displaying a personal identification number, and registering reference information used to permit verification of validity of the personal identification number on the authentication server. Further, the user authentication system includes an inquiry device for requesting verification of validity of the personal identification number from the authentication server, and receiving and displaying results of the verification. Furthermore, the user authentication system includes an authentication server for storing issuance information while issuing the personal identification number, determining whether to permit the verification of the validity of the personal identification number, if the inquiry device requests the verification of the validity, and replying with results of the verification, if it is determined that the verification of the validity is to be permitted.
