Claim:
A radio base station apparatus, comprising: a determining unit that dynamically determines, based on both quality information and traffic information which are collected for each of a first link used for direct communication between a first radio terminal and the radio base station apparatus, a second link used for direct communication between a second radio terminal and a fixed radio relay apparatus, and a third link used for relay transmission between the radio base station apparatus and the fixed radio relay apparatus, of a plurality of sub-frames in a radio frame as radio resources, a number of sub-frames to be allocated to each of the first link, the second link, and the third link and an allocation timing therefor; and a notifying unit that notifies the fixed radio relay apparatus of allocation information including the number of sub-frames to be allocated to the third link used for the relay transmission and the allocation timing therefor in a period of at least once in each radio frame and at a predetermined notification timing in each radio frame without needing to request for a radio resource from the fixed radio relay apparatus, the number of sub-frames and the allocation timing as the allocation information having been dynamically determined based on both the quality information and the traffic information.
