Claim of US Patent No. 10,972,991

1. A method performed by a first terminal operating out of a coverage of a base station, the method comprising:obtaining configuration information including information on a first transmission timing and a second transmission timing associated with a synchronization signal, wherein the first transmission timing and the second transmission timing occur in one or more transmission periods;
identifying whether a first synchronization signal is received from a second terminal in one of the first transmission timing and the second transmission timing in at least one of the one or more transmission periods;
in a case that the first synchronization signal is received in the first transmission timing, transmitting a second synchronization signal in the second transmission timing; and
in a case that the first synchronization signal is received in the second transmission timing, transmitting the second synchronization signal in the first transmission timing.
