Abstract

trata-se de métodos, sistemas e dispositivos para comunicação sem fio. uma estação-base pode estabelecer um intervalo de transmissão entre transmissões de enlace descendente (dl) e enlace ascendente (ul) em uma banda de espectro de radiofrequência (rf) compartilhada com o uso de duplexação por divisão de tempo (tdd). uma duração do intervalo pode se basear, pelo menos em parte, em uma duração permitida máxima de um sinal de preenchimento que corresponde a uma área de cobertura da estação-base. para reservar a banda compartilhada, um equipamento de usuário (ue) pode comunicar o sinal de preenchimento por uma duração de tempo que se baseia, pelo menos em parte, na duração permitida máxima e em uma distância geográfica entre o ue e a estação-base. os ues mais distantes da estação-base transmitem o sinal de preenchimento de durações mais curtas antes de enviar uma transmissão ul, de modo que as transmissões ul de diferentes ues cheguem ao mesmo tempo na estação-base independentemente da distância geográfica entre os ues.
