Abstract

Se expone un método y un aparato para enviar una indicacion de la calidad del canal )ICC) por la vía de un canal compartido, mientras que una unidad de transmision- recepcion inalámbrica (URTI) se encuentra en un estado del Generador_CAA, sin tener un canal dedicado asignado para la URTI. Una URTI realiza una medicion de al menos un parámetro y genera un ICC basado en la medicion. La URTI entonces transmite el ICC por la vía de canal de acceso aleatoriao (CAA). El ICC puede ser transmitido utilizando un preámbulo del CAA. Una pluralidad de secuencias de senales sonoras puede ser divididas en una pluralidad de grupos. La URTI puede seleccionar un grupo basado en el ICC y en la secuencia de la senal sonora, entre las secuencias de las senales sonoras en el grupo seleccionado para transmitir el preámbulo del CAA. El ICC puede estar anexado al preámbulo del CAA. El ICC puede ser transmitido por la vía de una parte de control o de una parte de datos del mensaje del CAA.
