ABSTRACT:
A mobile station comprises a power detector, an averaging circuit, and a signal fade detector. The power detector measures a channel signal power (receive signal power) of a receive signal received by a receiver. The averaging circuit averages the receive signal power measured by the power detector. The signal fade detector detects the fade of the channel signal power with the average of the receive signal power. When the fade of the receive signal is detected, while a call request or a call response is being transmitted, after the receive signal power is recovered, a control circuit of the mobile station re-transmits the call request or the call response. When the fade of the receive signal is detected just before a call request or a call response is to be transmitted, the control circuit of the mobile station stops transmitting the call request or the call response. After the receive signal power is recovered, the control circuit of the mobile station transmits the call request or the call response.
