Abstract

Una unidad inalámbrica de transmisión/recepción (WTRU) multi-modo incluye al menos una antena, un primero y un segundo receptores en modo de comunicación y un primer transmisor en modo de comunicación. El primero y el segundo receptores reciben simultáneamente señales de la antena. El primer transmisor genera y envía un primer tipo de señal a la antena mientras que, al mismo tiempo, el segundo receptor recibe un segundo tipo de señal de la antena. En una forma de realización preferida, la WTRU incluye, además, un multiplicador de vector configurado para reducir o eliminar la interferencia de señales recibidas por el segundo receptor, interferencia producida por el primer transmisor. El multiplicador de vector ajusta la fase y la amplitud de ruido (es decir, ruido en banda espuria) medidas por el segundo receptor. La WTRU puede incluir, además, un segundo transmisor en modo comunicación configurado para generar y enviar un segundo tipo de señal a la antena.
