摘要：
Embodiments of the present invention disclose a method for controlling power of an uplink multiple-input multiple-output channel, and a user equipment that are used to support an uplink MIMO application scenario and implement control of transmit power of a UE. The method in the embodiments of the present invention includes: when total transmit power of a user equipment UE is greater than maximum allowed transmit power, performing, by the UE, power reduction for an uplink multiple-input multiple-output MIMO channel on which a main data transmission block and a secondary data transmission block are sent, so that the total transmit power of the UE after the reduction is less than or equal to the maximum allowed transmit power.
