Abstract

La presente invención se relaciona a métodos y disposiciones para distribuir la potencia de transmisión de UE entre múltiples portadoras de componente de UL, por ejemplo, en situaciones donde las portadoras de componente de UL residen en diferentes bandas o donde datos con diferente importancia se programan en las diferentes portadoras de componente y entre el PUSCH y el PUCCH cuando aquellos canales se transmiten simultáneamente. Para ser capaz de controlar la distribución de la potencia de transmisión disponible de un UE entre múltiples portadoras de componente de UL y/o entre el PUCCH y el PUSCH, factores de ponderación de potencia individuales a utilizarse por el UE se configuran por el eNB de acuerdo con modalidades de la presente invención. Los factores de ponderación de potencia se señalizan como corresponde al UE y se utilizan por el UE para ponderar el PUCCH y el PUSCH y/o diferentes portadoras de componente.
