Abstract

Un método y aparato para estimar e informar la calidad de un canal de comunicación inalámbrica entre una unidad inalámbrica de transmisión/recepción (WTRU) y un Nodo B. Una senal modulada es recibida desde el Nodo B a través del canal de comunicación y se lleva a cabo una estimación de canal en la senal modulada para proveer un estimado de canal. en una forma de realización, la senal modulada es demodulada en base al estimado de canal para proveer una senal demodulada y se obtiene un estimado de relación entre senal e interferencia (SIR) en base a la senal demodulada. La calidad del canal de comunicación es estimada en base al menos al estimado de SIR. En una forma de realización alternativa, se obtiene un estimado de SIR en base al estimado de canal. La calidad del canal de comunicación es estimada en base al estimado de SIR y a información adicional que incluye al menos uno entre información de velocidad de WTRU, distorsión de retardo y potencia de transmisión.
