Abstract

método de comunicação sem fio, dispositivo terminal e dispositivo de rede. trata-se de um método de comunicação sem fio, um dispositivo terminal e um dispositivo de rede capaz de determinar a relação qcl de blocos de sinal de sincronização (ssb). o método compreende: um dispositivo terminal receber um primeiro ssb em um espectro não licenciado; de acordo com um primeiro campo de bit e/ou um segundo campo de bit em um canal de difusão físico (pbch) do primeiro ssb, determinar um índice de ssb estendido do primeiro ssb e/ou um primeiro parâmetro n para determinar a relação quase colocalizada (qcl), em que n é um número inteiro positivo, a posição de bit do primeiro campo de bit no pbch é a mesma que a posição de bit de um campo de bit de intervalo de subportadora no pbch em um espectro licenciado e a posição de bit do segundo campo de bit no pbch é parcial ou completamente igual à posição de bit de um campo de bit de deslocamento de subportadora no pbch no espectro licenciado; e a posição de bit do segundo campo de bit no pbch é parcial ou completamente igual à posição de bit de um campo de bit de deslocamento de subportadora no pbch no espectro licenciado; e determinar a relação qcl do primeiro ssb e de outros ssbs de acordo com o índice de ssb estendido do primeiro ssb e n.
