Abstract

Un método y un aparato para controlar la transmision de un indicador de calidad de canal (CQI) en un sistema de comunicacion inalámbrica son presentados. Una unidad de transmision / recepcion inalámbrica (WTRU) determina, en cada intervalo de tiempo de transmision (TTi), si un temporizador CQI ha expirado. El temporizador CQI es reiniciado cada vez que un CQI es enviado hacia fuera por la WTRU. Si el temporizador CQI ha expirado, la WTRU determina si existe una oportunidad para un reporte CQI en un TTI actual. La WTRU envía en CQI si existe una oportunidad de reporte CQI en el actual TTI. De otra forma, la WTRU espera por un proximo TTI. La oportunidad de reporte CQI existe cuando hay data conexion - arriba para ser transmitida en el actual TTI, cuando la WTRU necesita enviar un acuse de recibo positivo (ACK) o un acuse de recibo negativo (NACK) en el cual TTI, o cuando una ráfaga de canal de control físico dedicado (DPCCH) está programada para ser transmitida en el actual TTI.
