Abstract:
An objective is to enable communications properly using an Scell even in a case where a radio base station which transmits “Activate command” and a radio base station which manages an Scell are different when “Inter-site CA” is performed. A radio base station eNB #1 according to the invention includes a transmission unit 12 configured to transmit an “Activate command” which is a command to activate a cell #B to a mobile station UE and thereafter notify a radio base station eNB #10 that the cell #B is activated.
