Claim Text:
1. A method for controlling power of an uplink multiple-input multiple-output channel, comprising: sending a main data transmission block and a secondary data transmission block on an uplink multiple-input multiple-output MIMO channel; performing, by a user equipment UE, power reduction for the uplink multiple-input multiple-output MIMO channel when total transmit power of the UE is greater than maximum allowed transmit power; and reducing the total transmit power of the UE to less than or equal to the maximum allowed transmit power, wherein the performing, by the UE, power reduction for an uplink MIMO channel on which a main data transmission block and a secondary data transmission block are sent, comprises: reducing, by the UE, first gain factors β if β if β
