<p>Provided in embodiments of the present invention are a method and device for controlling uplink transmission power. Provided in the present invention, the method for controlling uplink transmission power comprises: a transmission power parameter and a power distribution parameter transmitted by a network side are received, where the transmission power parameter indicates the maximum total transmission powers of an uplink control channel and of an uplink data channel, and the power distribution parameter indicates transmission power ratios (T/P) of the uplink data channel and of the uplink control channel; a current uplink total transmission power is determined; transmission powers of the uplink data channel and of the uplink control channel are controlled on the basis of the uplink total transmission power and of the T/P, thus increasing receiving signal-to-interference-plus-noise ratio of the uplink data channel under current channel conditions. The embodiments of the present invention implement an increase in the receiving signal-to-interference-plus-noise ratio of the uplink data channel under the current channel conditions, thus reducing interference to a certain extent, and solving the problem in the prior art that the coverage and volume of a cell network are reduced as a result that transmission power is increased during uplink transmission to resist interference.</p> |
