1. a kind of method of power control characterized by comprisingBase station determines transmission power control parameter, and the power contorl parameters are used to determine the maximum transmission power of user equipment;

  • The base station sends the transmission power control parameter to the user equipment;

    The base station indicates that the user equipment uses the maximum transmission power sending device of the user equipment to device signal;

    Further include;

    The base station indicates the user equipment according to formula;

    P (i)=min { PCMAX(i),10log10(M(i))+PO

    ·

    PL+f(i) } the current transmission power P (i) of the user equipment is calculated, wherein i is subframe number, PCMAXIt (i) is described on subframe iThe maximum transmission power of user equipment, M (i) are the frequency domain bandwidth distributed on subframe i, POFor the received intended recipient in the base stationPower, α

    are the path loss penalty coefficient that the base station determines, PL is the downlink path loss of the user equipment assessment, fIt (i) is the dynamic power adjustment amount on subframe i, when the user equipment is sent using the maximum transmission power of the user equipmentWhen signal, f (i)=f (i-1) or f (i)=0.
