RADIO COMMUNICATION SYSTEM, BASE STATION DEVICE, AND TRANSMISSION POWER CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To suppress a temporary increase in a processing load.SOLUTION: A base station device includes: an acquisition unit that acquires the reception quality of each of a plurality of carriers from a terminal device that performs primary cell connection to transmit and receive control channel signals using a carrier with the best reception quality of the plurality of carriers; a determination unit that determines the amount of increase in transmission power of any carrier on the basis of the reception quality acquired by the acquisition unit; a judgment unit that estimates whether or not switching of the primary cell connection will occur if the transmission power is increased by the amount of increase determined by the determination unit, and determines whether the transmission power should be increased or not depending on an estimation result; and an instruction unit that instructs a transmission unit to increase the transmission power of the carrier by the amount of increase if the judgment unit has determined that the transmission power should be increased.SELECTED DRAWING: Figure 3
