1. A method for adjusting a transmission power of a terminal in a digital mobile radio relay system, comprising:

  • receiving an idle frame transmitted by a repeater transceiver, wherein information of a transmission power of the repeater transceiver is carried in the idle frame;

    obtaining the transmission power of the repeater transceiver from the information carried in the idle frame;

    transmitting data in a preset transmission time slot, after entering a transmitting state;

    receiving a signal from the repeater transceiver in a reverse channel and calculating a strength value of the received signal;

    determining a transmission power of a next frame based on the transmission power of the repeater transceiver and the strength value of the received signal, in the case that data is to be continuously transmitted; and

    transmitting the next frame in a preset transmission time slot by using the determined transmission power of the next frame.
