Abstract

são reveladas técnicas para acessar um meio de comunicação compartilhado. um aspecto inclui comunicação através do meio de comunicação compartilhado de acordo com uma estrutura de quadro de duplexação por divisão no tempo (tdd) definindo um conjunto de subquadros de downlink e um conjunto de subquadros de uplink, cada subquadro de uplink sendo dividido em um período de lacuna de transmissão, um período isento de contenção, e um período sujeito à contenção, execução de um procedimento de contenção para contender pelo acesso ao meio de comunicação compartilhado durante o período de lacuna de transmissão, transmissão seletiva de um ou mais sinais de controle de uplink sujeito à contenção durante o período sujeito à contenção, e transmissão de um ou mais sinais de controle de uplink isento de contenção durante o período isento de contenção. um aspecto inclui receber um subquadro de downlink do meio de comunicação compartilhado e transmitir uma confirmação do subquadro de downlink durante um subquadro de uplink do meio de comunicação compartilhado, o subquadro de uplink ocorrendo pelo menos um número de subquadros predeterminado e/ou pelo menos uma quantidade de tempo predeterminada após o subquadro de downlink.
