Abstract

Se describen sistemas y metodologías que proporcionan técnicas para la búsqueda eficiente de células en un sistema de comunicación inalámbrica; en un aspecto, un patrón de reutilización de frecuencia puede ser generado aplicando cambios de frecuencia a señales de referencia transmitidas desde las células que proporcionan cobertura para Nodo B con base en las ID de célula o ID de grupo de células para las células; los cambios de frecuencia aplicados a las señales de referencia pueden entonces ser utilizados como una base para multiplexar señales de referencia provenientes de diferentes células utilizando multiplexión por división de frecuencias (FDM) o una combinación de FDM y otras técnicas de multiplexión; se puede realizar otros ajustes a las señales de referencia transmitidas desde células respectivas, tal como ajustes de potencia de transmisión, para mejorar el rendimiento de la detección.
