Abstract

Telecomunicaciones celulares y, más en particular, con la asignacion de senales de referencia a terminales moviles para la transmision del enlace ascendente. El proposito de la senal de referencia es calcular el canal del enlace ascendente en un radio de la estacion base. El objeto de la presente es reducir el impacto del escenario de interferencia en el peor de los casos en la recepcion de la senal de referencia. El objeto se logra mediante un método en donde los terminales moviles son asignados una pluralidad de senales de referencia para alternar entre transmisiones posteriores de acuerdo con un esquema de salto. Por lo tanto, las transmisiones del terminal movil con peor interferencia en otra celda colisionarán con la recepcion de diferentes terminales en la propia celda, aunque solo colisiones no frecuentes con cada una de ellas. Por lo tanto, también será posible detectar los datos recibidos desde los terminales moviles con la colision de baja frecuencia.
