Abstract:
1. A radio base station configured to be able to perform communication with a mobile station using a primary carrier and a secondary carrier which have different carrier frequencies, the radio base station comprising: a management unit configured to manage the number of mobile stations corresponding to each carrier; and a scheduling unit configured to perform a scheduling processing to a scheduling-target mobile station, in which the communication is set to be performed, in at least one of the primary carrier and the secondary carrier of the scheduling-target mobile station, based on the number of mobile stations corresponding to each carrier, wherein the scheduling unit is configured to perform the scheduling processing to the scheduling-target mobile station only in the primary carrier of the scheduling-target mobile station, when determining that the number of mobile stations corresponding to the primary carrier and the secondary carrier of the scheduling-target mobile station is greater than a predetermined threshold, and the scheduling unit is configured to separately perform the scheduling processing to the scheduling-target mobile station in the primary carrier and the secondary carrier of the scheduling-target mobile station, when determining that the number of mobile stations corresponding to the primary carrier and the secondary carrier of the scheduling-target mobile station is less than the predetermined threshold.
