RADIO COMMUNICATION TERMINAL AND TRANSMISSION POWER CONTROL METHOD

摘要

A first section (206) for measuring reception power measures the reception power of the individual channel signal transmitted with narrow directivity, and a second section (207) for measuring reception power measures the reception power of the common channel signal transmitted with wide directivity. A decision section (210) checks for a deviation of directivity based on the average reception power of the individual channel signal and the common channel signal. A transmission power controller (211) controls the transmission power based on the result of decision. If a base station transmits signals with narrow directivity, the cause of the decrease in reception power is adequately determined, and the transmission power is accurately controlled.
