Abstract

Se proporciona un método para asistir en la adaptacion de una senal desde un primer nodo (100) a un segundo nodo (120). El primer nodo se comunica con el segundo nodo en un sistema de comunicacion inalámbrico (110) a través de un vínculo de radio (130). El segundo nodo está configurado para contener un codigo, que a su vez comprende un conjunto de alternativas posibles de informacion que se utiliza para asistir en la adaptacion de la senal que proviene del primer nodo al segundo nodo. El segundo nodo puede seleccionar una alternativa de informacion de un codigo y enviarla al primer nodo para asistir al primer nodo a adaptar la senal. El primer nodo está configurado para conocer un numero de subconjuntos, y cada subconjunto comprende una parte de alternativas posibles de informacion. El método comprende los pasos de enviar la solicitud de configuracion al segundo nodo para que este restrinja la seleccion de alternativas de informacion a uno de los subconjuntos; recibir una alternativa de informacion del segundo nodo que se selecciono de entre al menos uno de los subconjuntos configurados de acuerdo con la solicitud de configuracion.
