Abstract
Un equipo de usuario (52) dúplex por división de tiempo, de espectro extendido, utilizando el equipo de usuario (52) cuadros con segmentos de tiempo para comunicación, recibiendo el equipo de usuario (52) órdenes de potencia y recibiendo una primera comunicación que tiene un nivel de potencia de transmisión en un primer segmento de tiempo, midiendo el equipo de usuario (52) un nivel de potencia de la primera comunicación recibida y determinando una estimación de pérdida de trayectoria basada parcialmente en el nivel medido de la primera comunicación recibida y en el nivel de potencia de transmisión de la primera comunicación, caracterizado porque el equipo de usuario (52) comprende: medios (108) para ajustar un nivel de potencia de transmisión para una segunda comunicación en un segundo segmento de tiempo desde el equipo de usuario (52) basándose parcialmente en la estimación de pérdida de trayectoria ponderada por un factor de calidad ajustado por las órdenes de potencia, en donde el factor de calidad disminuye a medida que aumenta el número de segmentos de tiempo entre los segmentos de tiempo primero y segundo.
