The invention discloses a multi antenna hybrid ARQ (MIMO - HARQ) including power distribution method, system: transmitter per data stream received SNR target value; according to the information of the current power allocation, in accordance with the pre merger calculation method of power flow distribution for all data received SNR the initial value of the power distribution information including the current and current for power transmission distribution the value of power for each data stream distribution value of each transmission before the transmission; choose a data SNR target with SNR is the initial value of the maximum difference from to distribution of power data streams as the data stream, without reducing the conditions of each road has power distribution data stream has reached the SNR under the current data flow distribution of power. The invention is not only applicable to the MIMO HARQ system without inter code interference, but also to the MIMO HARQ system with code stream interference.
