A first reception power measuring section 206 measures reception power of individual channel signals transmitted with a narrow directivity, and a second reception power measuring section 207 measures reception power of common channel signals transmitted with a wide directivity. A determining section

A first reception power measuring section 206 measures reception power of individual channel signals transmitted with a narrow directivity, and a second reception power measuring section 207 measures reception power of common channel signals transmitted with a wide directivity. A determining section 210 determines the presence or absence of a directional shift based on an average reception power of the individual channel signals and an average reception power of the common channel signals. A transmission power controlling means 211 performs transmission power control based on the determination result. This makes it possible to correctly determine the cause of a reduction in reception power and to control transmission power accurately.
