Abstract

a presente invenção refere-se a um método e um dispositivo de envio/recebimento de canal de difusão físico para solucionar um problema da técnica anterior de que um dispositivo terminal não pode obter informações de difusão exatas e, consequentemente, não pode acessar uma rede. no método, após receber (501) dois sinais de canal de difusão em dois canais de difusão físicos correspondentes em dois locais de recurso de tempo-frequência, o dispositivo terminal determina (502) que as informações além de um deslocamento de um local de recurso de tempo-frequência correspondente são os mesmos em duas informações de difusão carregadas nos dois sinais de canal de difusão, obtém (503) uma diferença de deslocamento de tempo entre os dois locais de recurso de tempo-frequência anteriormente mencionados, e gera uma sequência de código de embaralhamento com base na diferença de deslocamento de tempo; e o dispositivo terminal desembaralha (504) separadamente os dois sinais de canal de difusão com base na sequência de código de embaralhamento e em uma sequência de código de embaralhamento predefinida implantando, desse modo, a decodificação conjunta nos dois sinais de canal de difusão, para obter uma informação de difusão. desse modo, o dispositivo terminal pode acessar a rede com base em cada informação nas informações de difusão.
