Abstract

Se describe un dispositivo de estación base que lleva a cabo comunicación con un dispositivo de usuario y un enlace ascendente usando un canal compartido para de esta manera controlar la potencia de transmisión de un canal indicador de HARQ físico (PHICH) en relación al canal compartido. La potencia de transmisión para el PHICH se controla con base en información de calidad de radio (CQI) de enlace descendente reportada desde el dispositivo de usuario, información (ACK/NACK) mapeada al PHICH, y la presencia/ausencia de una concesión de programación de enlace ascendente que indica la transmisión del canal compartido.
