In an embodiment of the disclosure, the UE 30 may identify the information about the second synchronization signal without receiving, from the first base station 10, the information about the second synchronization signal or the information about the region in which rate matching is to be performed. The UE 30 may identify transmission timing, a transmission period, and a continuous transmission time of the second synchronization signal by receiving the second synchronization signal from the second base station 20. The UE 30 may perform rate matching on a signal received from the first base station 10 through the second frequency resource, based on the information about the second synchronization signal identified by the UE 30.
A method of sharing a frequency resource of the first mobile communication provider according to a request from a third base station or a third mobile communication provider, the method being performed by the first base station 10, will be described below.
