Abstract

Se describen técnicas para asignar secuencias de código de sincronización primario (PSC) y secuencias de código de sincronización secundario (SSC) a células en un sistema de comunicación inalámbrica; al menos una secuencia PSC y múltiples secuencias SSC pueden ser utilizadas para múltiples células en un Nodo B; en un diseño, las secuencias SSC disponibles en el sistema pueden ser acomodadas en grupos, donde cada grupo incluye M secuencias SSC diferentes; grupos adicionales de M secuencias SSC pueden ser formados con diferentes permutaciones (por ejemplo, diferentes desplazamientos cíclicos) de cada grupo de las M secuencias SSC; en un diseño, se pueden utilizar tres secuencias SSC, SSC(G1), SSC(G2) y SSC(G3) para las tres células en el Nodo B; una primera permutación que incluye SSC(G3), SSC(G1) y SSC(G2) puede ser utilizada para tres células en otro Nodo B; una segunda permutación que incluye SSC(G2), SSC(G3) y SSC(G1) puede ser utilizada para tres células en todavía otro Nodo 3.
