Abstract

Se describen un metodo y sistema para efectuar busqueda de celda inicial en sistemas de comunicacion inalambricas donde las celdas inadecuadas son excluidas. Las frecuencias almacenadas son buscadas exhaustivamente y frecuencias iniciales son buscadas de manera no exhaustiva. Pueden ser buscadas frecuencias iniciales exhaustivamente en ciertas circunstancias. Cuando se efectuan busquedas de celda inicial exhaustiva, los codigos de sincronizacion primaria que conducen a celdas inadecuadas son excluidas de busquedas de celda inicial posteriores efectuadas sobre la misma frecuencia.
