Abstract

La presente invención describe un método, aparato y sistema de control de potencia. Una entidad de control vectorial adquiere un factor de control de potencia Diik de un i-ésimo extremo de transmisión en un k-ésimo suboperador, en donde el i-ésimo extremo de transmisión es un transceptor de transceptores M situados en un extremo de oficina central, 1=k=K, y K indica una cantidad de suboperadores; y envía el factor de control de potencia Diik al i-ésimo extremo de transmisión, de modo que si se determina, de acuerdo con el factor de control de potencia Diik, que el factor de control de potencia Diik es menor que un factor de ganancia de potencia gik, de una señal de transmisión actual del i-ésimo extremo de transmisión, en el k-ésimo suboperador, el i-ésimo extremo de transmisión modifica el factor de ganancia de potencia gik de la señal de transmisión actual, de tal forma que un factor de ganancia de potencia modificado gik, sea menor o igual que el factor de control de potencia Diik, lo cual puede resolver un problema existente en un método de control de potencia en la técnica anterior, en el que el control es complejo y el desempeño de transmisión de señal de una línea entera se reduce.
