Abstract

Un sistema de comunicación inalámbrica provee un método y aparato para traspaso con continuidad ("soft handover") y traspaso entre sectores pertenecientes a una misma estación base ("softer handover") de una unidad inalámbrica de transmisión/recepción (WTRU) entre dos o más estaciones base y/o sectores de estación base. Una unidad de control de red asigna estaciones base seleccionadas para transmitir datos de comunicación a la WTRU en base a la WTRU que está dispuesta en un rango geográfico de servicio de una estación base o de un sector de la estación base. Un receptor detector conjunto (JD) de la WTRU está configurado para recibir y procesar una o más señales de datos inalámbricas en cada una de una serie de tramas de tiempo donde cada señal recibida dentro de una ranura de tiempo común tiene una única codificación de canal de los mismos datos de comunicación. El receptor JD tiene una pluralidad de estimadores de canal que estiman señales recibidas dentro de una ranura de tiempo común y un combinador configurado para decodificar y combinar los estimados de canal para derivar una señal de datos resultante.
