What is claimed is:1. A method of communicating with a user equipment by using a frequency resource of a second mobile communication provider in a mobile communication system, the method being performed by a first base station of a first mobile communication provider, the method comprising:requesting to permit the first base station to use a second frequency resource of the second mobile communication provider; transmitting, to the user equipment, setting information, for establishing communication using the second frequency resource of the second mobile communication provider, through a first frequency resource of the first mobile communication provider; and communicating with the user equipment through the second frequency resource, based on the setting information, wherein the setting information comprises information about a method of obtaining, by the user equipment, synchronization information corresponding to the first base station, and wherein the synchronization information is obtained through at least one of a periodic synchronization signal or an aperiodic preamble and comprises identification information of the first mobile communication provider. 2. The method of claim 1 , further comprising:receiving a response to the request for the permission, wherein the transmitting of the setting information comprises transmitting the setting information, based on the received response. 3. The method of claim 1 , further comprising, unless a negative acknowledgment (NACK) is received with respect to the request for the permission, determining that the request is permitted. 4. The method of claim 1 ,wherein the identification information is uniquely predetermined for the first mobile communication provider to distinguish between a plurality of mobile communication providers or is allocated to the first base station from a second base station of the second mobile communication provider, and wherein the method further comprises transmitting the identification information of the first mobile communication provider to the user equipment. 5. The method of claim 1 , further comprising:requesting a second base station of the second mobile communication provider to allocate time and frequency resources to the first base station for communication with the user equipment by using the second frequency resource; receiving allocation of the time and frequency resources from the second base station; and transmitting the periodic synchronization signal or the aperiodic preamble to the user equipment by using the allocated time and frequency resources, wherein the communicating with the user equipment comprises communicating with the user equipment, based on the synchronization information included in the periodic synchronization signal or the aperiodic preamble. 6. The method of claim 1 ,wherein the setting information comprises information about a method of obtaining, by the user equipment, synchronization information corresponding to the first base station, wherein the synchronization information is obtained based on a first synchronization signal transmitted through the first frequency resource or a second synchronization signal transmitted through the second frequency resource, and wherein the first synchronization signal corresponds to the first base station and the second synchronization signal corresponds to a second base station of the second mobile communication provider. 7. The method of claim 6 , wherein the information about the method of obtaining the synchronization information comprises information about an offset between the first or second synchronization signal and the synchronization information for communicating the user equipment with the first base station through the second frequency resource. 8. The method of claim 1 , further comprising:obtaining information about a second synchronization signal corresponding to a second base station of the second mobile communication provider; determining a region in which rate matching is to be performed when the user equipment receives data from the first base station, based on the information about the second synchronization signal; and transmitting, to the user equipment, information about the region in which rate matching is to be performed, wherein the information about the second synchronization signal comprises information about transmission timing of the second synchronization signal and information about a transmission period of the second synchronization signal. 9.
