Abstract

a invenção refere-se a um dispositivo de processamento para gerar uma sequência de sinais de sincronização secundários a ser utilizada junto de uma sequência de sinais de sincronização primários para sincronização, o dispositivo de processamento sendo configurado para: determinar um primeiro deslocamento cíclico e um segundo deslocamento cíclico com base em pelo menos uma id de célula, em que pelo menos um dentro o primeiro deslocamento cíclico e o segundo deslocamento cíclico é associado à sequência de sinais de sincronização primários por ser determinado com base também em um índice da sequência de sinais de sincronização primários; e gerar a sequência de sinais de sincronização secundários com base em um somatório de módulo-2 de uma primeira sequência binária deslocada ciclicamente por um primeiro deslocamento cíclico e uma segunda sequência binária deslocada ciclicamente por um segundo deslocamento cíclico, de modo que se duas sequências de sinais de sincronização secundários geradas associadas a uma sequência de sinais de sincronização primários forem versões deslocadas ciclicamente uma da outra, as duas sequências de sinais de sincronização secundários geradas são versões deslocadas não consecutivamente uma da outra. além disso, a invenção também refere-se a um nó de rede, um dispositivo de cliente, métodos correspondentes, um programa de computador, e um produto de programa de computador.
