Abstract

Se describen un método y aparato para enviar una indicación de calidad de canal (CQI) por medio de un canal compartido mientras que la unidad de transmisión/recepción inalámbrica (WTRU) se encuentra en un estado Celda_FACH sin tener un canal dedicado ubicado para la WTRU. Una WTRU realiza una medición de al menos un parámetro y genera una CQI basada en la medición. La WTRU transmite entonces la CQI por medio de un canal de acceso aleatorio (RACH). La CQI podrá transmitirse utilizando un preámbulo de RACH. Una pluralidad de secuencias de identificación podrán dividirse en una pluralidad de grupos. La WTRU puede elegir un grupo en base a la CQI y elegir aleatoriamente una secuencia de identificación entre las secuencias de identificación en el grupo seleccionado para transmitir el preámbulo de RACH. La CQI podrá anexarse al preámbulo RACH. La CQI podrá transmitirse por medio de una parte de control o una parte de datos del mensaje de RACH.
