Radio communication equipment with transmission rate regulating function

摘要

An RSSI detector 2 detects the electric field level of a received signal, and a transmission rate determiner 5 determines an initial transmission rate value from the detected electric field level. A radio unit 1 transmits the determined initial value to a base station 20. In response thereto, the base station 20 transmits a control signal at the assigned initial transmission rate value. A bit error rate value detector 4 detects a bit error rate of the control signal, and a transmission rate determiner 5 finely regulates the initial value according to the detected bit error rate. An optimal transmission rate is thus determined.
