Abstract

Se proveen métodos y dispositivos en donde un equipo de usuario transmite utilizando al menos dos antenas de transmisión por enlace ascendente y recibe un conjunto de señales de control en la dirección de enlace descendente desde una red celular. El equipo de usuario estima una calidad de señal recibida de cada señal de control en dicho conjunto de señales de control y determina que, en base a dicha calidad de señal recibida, las señales de control se han recibido de un modo fiable. El equipo de usuario deriva uno o más parámetros relacionados a la operación de diversidad en transmisión por enlace ascendente utilizando un subconjunto de señales de control del conjunto de señales de control, dicho subconjunto solamente incluye señales de control determinadas como recibidas de un modo fiable; y transmite en la dirección de enlace ascendente aplicando uno o más parámetros derivados para controlar la operación de diversidad en transmisión por enlace ascendente. La exactitud de los valores de parámetros de diversidad de transmisión derivados/establecidos por el UE se puede mejorar. Esto mejorará el desempeño de la diversidad en transmisión por enlace ascendente y también reducirá la interferencia a las celdas próximas.
