Abstract: 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.

Abstract: A pilot signal transmission method, a channel estimation method, and an apparatus are provided, and the method for a pilot signal transmission includes: transmitting a pilot signal 1 CPICH1 over a first antenna, and transmitting a pilot signal 2 CPICH2 over a second antenna; transmitting a pilot signal CPICHk1 over a k1th antenna; and when it is determined that a terminal of a first category in the MIMO system is scheduled, transmitting a pilot signal CPICHk2 over the k1th antenna. Interference caused by a pilot signal to a traditional terminal is better reduced, performance of the traditional terminal is ensured while the terminal of the first category properly works in the MIMO system, and power consumption for transmitting a pilot signal is effectively reduced.
