    摘要： A method and an apparatus for obtaining synchronization of a terminal for communication between devices when a base station collapses are provided. The method includes, when a preamble signal is not received from the base station, maintaining a first synchronization for a predetermined time using a timer, transmitting a first preamble signal at a first synchronization point, performing a synchronization procedure with at least one neighbor terminal based on the first preamble signal, and, after the synchronization procedure, performing communication with the at least one neighbor terminal. In addition, when a preamble signal is not received from a base station, a first preamble signal from a relevant neighbor terminal is monitored for a predetermined time. When the first preamble signal is not received from the relevant neighbor terminal for the predetermined time, a second preamble signal is transmitted at an arbitrary point.

    摘要： A 5th-generation (5G) or pre-5G communication system which is to support a higher data transfer rate beyond a 4G communication system such as a long term evolution (LTE) is provided. The method for transmitting a downlink signal by a base station in a wireless communication system supporting non-orthogonal multiple access (NOMA) includes the steps of selecting a pair of terminals including one short-distance terminal and at least one long-distance terminal which will share an identical downlink transmission resource, generating a superimposed signal in which a signal for the short-distance terminal and a signal for the long-distance terminal are superimposed on one another, generating information necessary for cancelling the signal of the long-distance terminal from the superimposed signal, transmitting the generated information necessary for cancelling the signal of the long-distance terminal to the short-distance terminal, and transmitting the generated superimposed signal to the pair of terminals.
