Resource allocation device for controlling frequency interference of Femtocell Base Station and, Method therefor

摘要

The present invention relates to a femtocell base station, and more particularly, to an apparatus and method for allocating frequency resources to each base station in order to control frequency interference between femtocell base stations or interference between a femtocell base station and a macrocell base station. A resource allocation apparatus according to an embodiment of the present invention is a resource allocation apparatus for controlling frequency resource interference between base stations, the apparatus comprising: at least one usage pattern for a frequency frame composed of sub- A usage pattern generation unit for generating the usage pattern and the pattern reuse index; And a usage pattern allocator allocating at least one usage pattern generated by the usage pattern generator to a base station. According to another aspect of the present invention, there is provided a resource allocation method for controlling frequency resource interference between base stations, the method comprising: dividing a frequency frame into subframes of a constant time unit; A usage pattern generation step of generating at least one usage pattern for the frequency frame using a resource use rate and a pattern reuse index; And a usage pattern allocation step of allocating the generated at least one usage pattern to a base station.
