Abstract
The present invention discloses a method and a system for controlling an uplink transmitting power, and a base station, wherein the method comprises: determining respective power control parameters of each frequency partition in a system whose uplink frequency band is divided into a plurality of frequency partitions, wherein each frequency partition comprises a plurality of physical sub-carriers; and a base station transmitting the power control parameters of all or part of the frequency partitions to a terminal, so that the terminal determines a transmitting power on a sub-carrier included in a corresponding frequency partition according to the power control parameters. By using the present invention, the power control parameters of a plurality of frequency partitions of an uplink frequency band are transmitted to the terminal, so that the terminal determines the transmitting power on the sub-carrier included in the corresponding frequency partition according to the power control parameters, which can solve the problems that the methods for controlling the uplink transmitting power in related technology is not flexible and can not effectively improve the uplink performance of the …
