The present invention discloses a method for controlling a transmit power in a multichannel system, a receive end, and a transmit end. The method includes: receiving, through N receive channels, N signals sent by a transmit end, where the N signals include a channel estimation sequence; determining a total receive power of an i th receive channel; determining a channel matrix according to a received channel estimation sequence; determining a useful receive power of the i th receive channel according to the channel matrix and the total receive power of the i th receive channel; determining, according to the channel matrix and a receive power that is required by single-channel communication, a receive power required by the i th receive channel; and sending a power adjustment message to the transmit end if the useful receive power of the i th receive channel does not match the receive power required by the i th receive channel, so that the transmit end adjusts a transmit power of an i th signal. According to the method for controlling a transmit power in a multichannel system, the receive end, and the transmit end in the embodiments of the present invention, the impact of fading variation in a multichannel system can be reduced. |
