    • A mobile radio communication apparatus includes a switch which outputs a strength of a received radio frequency signal or a power strength of a radio frequency signal in accordance with an input of a switch control signal supplied from a switch control circuit. The switch control signal is supplied during a transmission time slot allotted to the mobile radio communication apparatus by the base station so that the switch outputs the power strength of the radio frequency signals in the same period of the transmission time slot and the strength of a received radio frequency signals in the same period of an other time slot. The strength of the received radio frequency signals and the power strength of the radio frequency signals are supplied to an analog-to-digital converter which converts the applied signal into a digital signal and supplies the digitalized signal to a level detector. The level detector detects a level of the strength of the radio frequency signals and a level of the power strength of the radio frequency signals which are used for monitoring condition of a transmission and a reception of the radio communication apparatus.
    • 移动无线电通信装置包括根据从开关控制电路提供的开关控制信号的输入输出接收的射频信号的强度或射频信号的功率强度的开关。 在由基站分配给移动无线电通信装置的传输时隙期间提供开关控制信号,使得开关在传输时隙的相同周期中输出射频信号的功率强度和接收的强度 射频信号在同一时段的另一个时隙。 接收到的射频信号的强度和射频信号的功率强度被提供给模数转换器,其将所施加的信号转换成数字信号,并将数字化信号提供给电平检测器。 电平检测器检测射频信号的强度的水平和用于监视无线电通信装置的发送和接收的状态的射频信号的功率强度的水平。
