RELAY CONTROL STATION, REPEATER, AND INTERFERENCE SUPPRESSING METHOD

摘要

A relay control station includes a power control unit that determines, on the basis of a power value of each of demultiplexed signals measured by the repeater and an expected power value of each of the demultiplexed signals, a gain control amount provisional value for each of the demodulated signals and calculates a gain control value of each of the demultiplexed signals for the repeater on the basis of a ratio between a sum of power estimation values of all the demultiplexed signals obtained when the gain control amount provisional value is applied and a sum of power values of all the demultiplexed signals measured by the repeater and the gain control amount provisional value; and a repeater interface unit that notifies the repeater of the gain control amount calculated by the power control unit.

主权项

1. A relay control station that controls a repeater in a communication system in which a transmitter transmits data to a receiver serving any beam via the repeater including one or more beams, the relay control station comprising:
a power control unit that determines, on a basis of power values of a plurality of demultiplexed signals measured by the repeater and each expected power value of the demultiplexed signals, a gain control amount provisional value for the demodulated signals and calculates a gain control value of the demultiplexed signals for the repeater on a basis of a ratio between a sum of power estimation values of the demultiplexed signals obtained when the gain control amount provisional value is applied and a sum of the power values of the demultiplexed signals and the gain control amount provisional value, the demultiplexed signals being obtained by the repeater demultiplexing a reception signal received from the transmitter; and a repeater interface unit that notifies the repeater of the gain control amount calculated by the power control unit as a control amount used for gain control performed on the demultiplexed signals by the repeater.
