3rd optimal value sending module, for by the optimal value of the T1 and the base station transmitting power P10 most The figure of merit is sent to the base station, using cause the base station when a length of gained optimal value T1 in using numerical value as institute The transmission power P10 for obtaining optimal value carries out data transmission；By the optimal value of the T1 and the terminal transmission power P20 optimal value is sent to the terminal, with cause the terminal when a length of gained optimal value T1 in number It is worth and carries out data transmission for the transmission power P20 of gained optimal value；By the optimal value of the T1 and it is described in it is secondary The optimal value for penetrating power P 30 is sent to the relaying, with cause it is described relaying when a length of gained optimal value T1 The interior transmission power P30 using numerical value as gained optimal value carries out data transmission.
