Abstract

Esta invención provee un método para controlar la potencia de transmisión de un canal compartido de enlace ascendente físico, que incluye: cuando sólo hay información de control de enlace ascendente pero no datos de canal compartido de enlace ascendente enviados a través del canal compartido de enlace ascendente físico, se fija la potencia de transmisión del canal compartido de enlace ascendente físico de acuerdo con el número total de bits contenidos en una señal indicadora de la calidad del canal y su comprobación redundante cíclica correspondiente, así como una desviación de la amplitud. Esa invención provee también un sistema para controlar la potencia de transmisión en un canal compartido de enlace ascendente físico. El método y el sistema descritos en esta invención pueden asegurar el funcionamiento general de un sistema.
