Abstract:
1. A radio base station that forms a predetermined cell or sector and allocates a radio resource corresponding to the predetermined cell or sector to a radio terminal, the radio base station comprising: continuous radio resource number acquisition unit acquires a number of continuous radio resources determined by a radio state between the radio terminal and the radio base station, the acquired number selected from a predetermined set of numbers; a non-allocatable radio resources specifying unit configured to acquire a total number of radio resources and determine, for each number in the predetermined set of numbers, a remainder value by dividing the acquired total number of radio resources by that respective number of the predetermined set, each said remainder value corresponding to a number of non-allocatable radio resources for the respective number of the predetermined set; a search space calculation unit configured to determine search regions for a predetermined radio terminal based on the acquired number of continuous radio resources for the predetermined radio; and an allocating unit configured to allocate continuous non-allocatable radio resources of the specified radio resources to the predetermined radio terminal, the continuous non-allocatable radio resources included in one of the determined search regions where all radio resources are not used and having a number of continuous radio resources larger than a number of continuous radio resources corresponding to the predetermined radio terminal.
