Abstract

Provided are a communication system for mitigating interference by a relay in a cell, a base station and a communication control method for the base station. The provided base station comprises: a reception unit which receives location information and/or wireless signal information from each of a plurality of terminals and one or more relays which are located within a cell region; and a frequency allocation unit which identifies an interference terminal, which communicates with the base station using a part of a first frequency band and causes interference with the one or more relays, among the plurality of terminals, and allocates another frequency band to the interference terminal, wherein the first frequency band is a frequency band used for communication between the one or more relays and terminals, and the identification of the interference terminal is achieved using location information and/or wireless signal information. According to the present invention, the interference between a base station and a relay link within a cell is efficiently reduced.
