Abstract
A radio base station apparatus wherein even when a single-base-station transmission and a plural-base-station cooperative transmission are implemented at the same time, the terminal-to-base-station feedback information amount and the inter-cell interference (ICI) can be reduced. A base station uses a first transmission mode, in which only the base station implements a signal transmission, and a second transmission mode, in which the base station implements a cooperative signal transmission together with another radio base station apparatus, to communicate with one or more radio terminal apparatuses. A setting unit sets, as a particular frequency band whose reception quality is to be measured, one of first and second frequency bands that are parts of a band used for communication with the terminals. A deciding unit decides, as the transmission mode for the terminals, one of the first and second transmissions based on the reception quality of the particular frequency band.
