Abstract

Se describen sistemas y métodos relacionados con la exploración de haz no adaptativa en una red inalámbrica. En algunas modalidades, se provee un método de operación de un nodo de transmisión (12) para realizar exploración de haz no adaptativa para patrones de haz de transmisión (16) del nodo de transmisión (12) que divide un área de cobertura de servicio (18) del nodo de transmisión (12) en celdas de partición de transmisión (20). El método transmite una señal conocida usando cada uno de los múltiples patrones de haz de exploración para cada una de las múltiples etapas de exploración de haz sobre ranuras de recursos de radio no superpuestas. Los patrones de haz de exploración para las etapas de exploración de haz son tales que cada combinación única de patrones de haz de exploración que consisten en un patrón de haz de exploración de cada una de las etapas de exploración de haz corresponde a un patrón de haz de transmisión diferente (16) del nodo de transmisión (12). Este enfoque de exploración de haz de etapas múltiples provee un proceso exponencialmente más eficiente para la exploración de haz que el enfoque de Barrido de Haz Secuencial (SBS) convencional.
