Abstract

Se proporciona un método de control de transmisión de potencia capaz de controlar, de manera adecuada, la potencia transmitida de un dispositivo de estación móvil que tiene una pluralidad de antenas de transmisión, y un dispositivo de estación móvil. El control de transmisión de potencia de un enlace ascendente de un dispositivo de estación móvil que tiene una pluralidad de antenas de transmisión involucra las siguientes etapas: una etapa que mide la pérdida de trayectoria (PL) al menos de una de una pluralidad de antenas de transmisión; una etapa que ajusta la pérdida de trayectoria representativa (PL') en función de la pérdida de trayectoria medida; una etapa que determina la potencia transmitida total (Ptx) del dispositivo de estación móvil en función de la pérdida de trayectoria representativa (PL'); y una etapa que determina la potencia transmitida (PTXn) de cada antena de transmisión mediante la distribución de la potencia transmitida total (Ptx) a la pluralidad de antenas de transmisión.
