Data transmission method and equipment

The invention claims a data transmission method, a support from three or more heat dissipation patterns transmission from a transmitter the signal, the is composed characterised, and secondary common control signals of adjusting component of the power ratio between pilot signals and primary and secondary common control signal output opening, and aid of the primary common control signal in the most two radiation pattern emitting, and a aid of a secondary common control signal at least one radiation pattern transmission, launched the special pilot signal at least user signal of the adjustable power transmission together, so on secondary common control signal with the aid of the same radiation pattern and special pilot signal powerLayer, a primary common control signal with the aid of the heat transmission according special pilot signal the ratio of power, the power ratio with corresponding secondary primary and pilot signals is a reverse ratio, and the secondary common control signal is provided with a channel estimation measurement in receiver with the aid of the specific control signal of the radiation pattern transmission.
