Abstract

métodos, sistemas e dispositivos para comunicação sem fio são descritos. alguns sistemas de comunicações sem fio podem suportar a comunicação entre uma estação base e um equipamento de usuário (ue) durante intervalos de tempo de transmissão (ttis) possuindo comprimentos diferentes. as técnicas descritas aqui permitem que um ue utilize configurações adequadas para comunicar durante um tti encurtado (stti) alocado para a comunicação em uplink (por exemplo, transmissões de informação de controle em uplink). em um exemplo, o ue pode ajustar uma energia de transmissão para uso para transmitir a informação de controle em uplink durante um stti com base no comprimento do stti ou com base no número de símbolos alocados para transmitir a informação de controle em uplink no stti. em outro exemplo, o ue pode determinar um padrão de pulo de frequência para uso na transmissão da informação de controle em uplink durante um stti com base no fato de se uma parte do stti está alocada para outra transmissão (por exemplo, uma transmissão de sinal de referência sonoro (srs)).
