Abstract

Se describe un equipo de usuario (UE) que soporta transmisión de varias antenas por medio de varios amplificadores de potencia que pueden operar en un modo de amplificador de potencia (PA) reducida. Cuando se opera en el modo de PA reducida, un subconjunto de los amplificadores de potencia del UE se usa para transmitir señales de enlace ascendente. Un UE puede enviar una señal de preferencia a un e-Nodo B para solicitar que el UE opere en el modo de PA reducida.
