Abstract

um método, um aparelho e um produto de programa de computador para comunicação sem fios são providos. o aparelho determina que um primeiro sinal de temporização de fonte de temporização externa está disponível em um primeiro ue. o aparelho também sincroniza o primeiro ue utilizando o primeiro sinal de temporização baseado em fonte de temporização externa quando o primeiro sinal de temporização de fonte de temporização externa está disponível. adicionalmente, o aparelho transmite um sinal de sincronização indicando que o primeiro ue é sincronizado usando um sinal de temporização de fonte de temporização externa.
