Abstract

La descripción se refiere a métodos y dispositivos para realizar control de potencia de enlace ascendente en un sistema de radiocomunicaciones. Un método de ejemplo comprende un paso de recibir (111), en un equipo de usuario (UE) un comando de control de potencia de transmisión (TPC) El método también comprende, si el UE no tiene una transmisión de enlace ascendente programada para una subtrama asociada con el comando de TPC, un pase de acumular (113), por el UE, el comando de TPC con comandos de TPC previamente recibidos con base en si el UE ha alcanzado una potencia de transmisión máxima o una potencia de transmisión mínima en un formato de referencia para un Canal compartido de Enlace Ascendente Físico (PUSCH), Señal de Referencia de Sondeo (SRS) o Canal de Control de Enlace Ascendiente Físico (PUCCH) Por lo tanto, el UE está habilitado par recibir comando de TPC mientras el UE no está transmitiendo nada en el enlace ascendente.
