1. A method of operating a node unit of a distributed antenna system (DAS), the method comprising:
transmitting, by the node unit, identification information for determining whether the node unit interoperates with at least one radio service device of a spectrum shared system (SSS) to a system controller of the SSS, wherein the node unit is communicatively connected to the at least one radio service device, and when the node unit interoperates with the at least one radio service device, the at least one radio service device is used as a signal source of the DAS;
receiving, by the node unit, allocation information including a result of allocating shared radio resources according to a result of the determining of interoperating from the system controller; and
operating, by the node unit, according to the allocation information.
