Claim Text:
1. A micro base station to be used in a heterogeneous cellular network, the micro base station having resources including frequency bands and time slots and being available for a user to use, the heterogeneous cellular network comprising a plurality of base stations including a macro base station and the micro base station, the micro base station comprising: an information acquiring part configured to acquire configuration information and load information of the micro base station, and to acquire configuration information and load information of a neighboring base station adjacent to the micro base station from the neighboring base station; and a resource selection part configured to select a part of the resources from the resources to provide the selected part of the resources to the user based on the configuration information and the load information of the micro base station and the neighboring base station, which are acquired by the information acquiring part, wherein: all of the resources possessed by the micro base station are divided into N resource blocks, and that M resource blocks is selected from the N resource blocks as the part of the resources to be provided to the user, where N and M are positive integers and satisfy N≧M; the resource selection part calculates a system parameter c based on the transmitting powers of the macro base station and the micro base station, and calculates a value of the M resource blocks in accordance with the following equations, where um represents the user rate requirement of the micro base station, uM represents the user rate requirement of the macro base station, ρm represents the micro base station density, ρM represents the macro base station density, λm represents the user density of the micro base station, and λM represents the user density of the macro base station.
