BASE STATION, TRANSMISSION POWER CONTROL METHOD FOR BASE STATION, PROCESSING APPARATUS, STORAGE MEDIUM STORING PROGRAM, AND COMMUNICATION SYSTEM

摘要

A base station 1 includes a radio communication unit 11 and a power ratio control unit 15. The radio communication unit 11 is capable of forming a serving HS-DSCH cell (primary cell) and a secondary-serving HS-DSCH cell (secondary cell), and transmitting a physical channel for data transmission in each of the primary and secondary cells. The power ratio control unit 15 is adapted, when a predetermined condition is satisfied, to control the radio communication unit 11 so as to lower the transmission power of secondary cell in comparison to the transmission power of the primary cell. In this way, the interference to a nearby cell caused by the base station 1 is suppressed.
