Abstract

Un método implementado en una unidad de transmisión/recepción inalámbrica (WTRU) para transmitir un reporte de indicación de calidad de canal (CQI) u otro reporte de medición comienza recibiendo un activador. Un reporte de CQI es transmitido a un Nodo B blanco de transferencia hasta que se alcanza una condición de interrupción. La WTRU dejará de transmitir reportes de CQI al Nodo B blanco si se alcanza la condición de interrupción. Una WTRU configurada para efectuar el método incluye una antena, un transmisor/receptor conectado a la antena, y un procesador que se comunica con el transmisor/receptor, el procesador configurado para transmitir el reporte de CQI al Nodo B blanco de transferencia.
