Abstract: Actual calculated throughput is presented to the user before the start of communications. A transmission and receiving section of a radio communication terminal transmits a first signal to a radio base station while the radio communication terminal is in an idling state to request a second signal (such as null data) used to calculate a transfer rate (such as throughput) expected in communications, and receives the second signal transmitted by the radio base station in response to the first signal. When the second signal having the amount of information specified in advance is received, a signal processing section calculates the transfer rate according to the time required from the start of receiving of the second signal to when the amount of information is reached, and the amount of information of the second signal received.
