Abstract:
A transmission power control method for controlling the power of a signal transmitted between a base station and a mobile terminal which constitute a mobile communication system, comprising, in said mobile terminal, the steps of:detecting a signal fluctuation that occurs on a down link on which a signal is transmitted from said base station to said mobile terminal, and generating power control information for compensating for a signal fluctuation that occurs on an up link on the basis of said detected signal fluctuation:compensating for, by said generated power control information, the power of a signal that is transmitted on said up link from said mobile terminal to said base station; andtransmitting, from said mobile terminal to said base station, said power control information that has been used for compensating for said transmission power, further comprising the steps of:comparing said generated power control information and a maximum permissible compensation value;temporarily stopping the transmission if said generated power control information is larger than said maximum permissible compensation value; andcompensating for the transmission power if said generated power control information is equal to or smaller than said maximum permissible compensation value.
