Terminal in digital mobile radio relay system, transmission power regulation method and system thereof
First Claim
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.

Abstract
A terminal in a digital mobile radio relay system, a transmission power regulation method and a system thereof are provided. The method includes that an idle frame sent from a relay station is received, the idle frame carries transmission power information of the relay station (201); the transmission power of the relay station is obtained according to the information in the idle frame (202); after a transmission state is entered, data is transmitted in assigned transmission time slots (203); a signal of the relay station is received via a reversal channel and a strength value of the received signal is calculated (204); when data transmission is required to be continued, the transmission power of a next frame is determined based on the transmission power of the relay station and the strength value of the received signal (206); according to the determined transmission power of the next frame, the data of next frame is transmitted in assigned transmission time slots.
