Abstract: A wireless communication system includes a macro-base station device and a CGS base station device normally connected to a CSG terminal device. When a non-CGS terminal device approaches the CGS base station device, the CGS base station device reduces a frequency band for transmitting packets to the CGS terminal device so as to reduce interference with the non-CGS terminal device while increasing transmission power to the CGS terminal device so as to compensate for degradation of radio quality due to a reduction of the frequency band. Based on existence or nonexistence of a non-CSG terminal device in the coverage area, the CSG base station device selects an appropriate antenna transmission mode and an appropriate scheduler mode while setting the number of OFDM symbols utilized by a physical control channel in notifying radio resource allocation information.

Abstract: A transmission power control device is able to capture the serving sector measurement information of a mobile station with respect to a serving sector and the neighboring sector measurement information of the mobile station with respect to a neighboring sector. The transmission power control device selects a power control mode based on a decision as to whether or not the neighboring sector measurement information has been captured in an applied time in the past. The power level of a mobile station is determined based on the selected power control mode. Thus, it is possible to reduce inter-cell interference and inter-sector interference because the power level of a mobile station is determined in light of communication environments, even though the mobile station is connected with a base station in an LTE-based communication system which cannot always detect the neighboring sector measurement information.
