摘要： Provided is a radio base station including a terminal detection unit that detects an uplink signal of a first terminal serviced by another base station, a storage unit that stores an allocation priority of a radio resource for a predetermined period, and a resource allocation unit that allocates a radio resource to a second terminal serviced by the radio base station, using the allocation priority of the radio resource stored in the storage unit. When the terminal detection unit detects the uplink signal of the first terminal, the resource allocation unit preferentially allocates a radio resource of an uplink of a high allocation priority to the second terminal while lowering an allocation priority of a radio resource estimated to be used next for the uplink by the first terminal.
