Abstract

método de comunicação sem fio, dispositivo de rede e dispositivo terminal. trata-se de um método de comunicação sem fio, um dispositivo de rede e um dispositivo terminal. o dispositivo de rede pode indicar um parâmetro quasi-colocalizado (qcl) em diferentes formas de indicação de acordo com se um bloco de sinal de sincronização (ssb) está associado ao bloco de informações do sistema 1 (sib1), o que é favorável para garantir que o dispositivo terminal receba corretamente informações de indicação qcl. o método inclui que: um dispositivo de rede determine as informações de indicação de associação ao sib1 de um primeiro ssb, sendo que as informações de indicação de associação ao sib1 são configuradas para indicar se o primeiro ssb está associado ao sib1; o dispositivo de rede determine se o primeiro ssb suporta informações de indicação de um parâmetro qcl e/ou uma forma de indicação para o parâmetro qcl no primeiro ssb com base em se o primeiro ssb está associado ao sib1; e o dispositivo de rede envia o primeiro ssb.
