Abstract

são descritos métodos, sistemas e aparelhos para comunicação sem fio. um aparelho sem fio pode identificar uma configuração de uplink/downlink (ul/dl) que define opções de configuração de sub-quadro para cada sub-quadro do quadro. por exemplo, a configuração ul/dl pode estabelecer parâmetros para funcionamento com duplexação por divisão de tempo (tdd) entre a estação base e o equipamento de usuário (ue). o aparelho sem fio (o ue ou estação base, por exemplo) pode determinar uma restrição para o sub-quadro do quadro com base na configuração ul/dl e em seguida determinar uma configuração de sub-quadro adaptativa com base na restrição. a configuração de sub-quadro adaptativa pode incluir um ou vários períodos de símbolos de downlink e um ou vários pros de símbolos de uplink. o aparelho sem fio pode em seguida comunicar-se durante o sub-quadro de acordo com a configuração de sub-quadro adaptativa e não de acordo com a configuração ul/dl original; e, uma vez que o sub-quadro adaptativo pode ser limitado pela configuração ul/dl identificada, a comunicação durante o sub-quadro pode evitar disrupção para os ues.
