ABSTRACT:
A radio communication apparatus, base station apparatus and communication terminal apparatus capable of predicting an accurate transmission rate before starting data communications to know download time and the like. In the apparatus, a packet CH demodulation section (103) demodulates received packet data. A pilot CH demodulation section (104) demodulates a received signal of a pilot channel. A reception state measuring section (105) measures the SIR from the received signal of the pilot channel. A transmission rate candidate selecting section (106) stores a calculation expression that associates CQI with SIR, and selects CQI by the calculation expression using the measured SIR. A transmission rate predicting section (108) averages selected CQI for a predetermined time to output a transmission rate prediction value. A transmission rate prediction control section (110) outputs information of the transmission rate prediction value to a display section (111) when detecting a key input. The display section (111) displays the transmission rate prediction value on a liquid crystal screen.
