Abstract
técnicas são descritas para comunicação sem fios. um método para comunicação sem fio em uma estação base inclui a recepção de acesso a um canal compartilhado de uma banda de espectro de frequência de rádio compartilhada, e multiplexação de janelas de comunicação de primeiro componente (cc) de comunicação e segundas janelas de comunicação cc no canal compartilhado. uma duração de multiplexação de domínio de frequência ortogonal (ofdm) símbolos das primeiras janelas de comunicação cc podem ser diferentes de uma duração de símbolos ofdm das segundas janelas de comunicação cc, e a multiplexação pode ocorrer no canal compartilhado mediante a contenção vencedora para acesso ao canal compartilhado. um método para comunicação sem fio em equipamento de usuário (ue) inclui a monitoração de um canal compartilhado de uma banda de espectro de frequência de rádio compartilhada para um primeiro cc escutar antes da fala (lbt) quadro, e recepção, em um segundo preâmbulo cc, uma indicação do primeiro quadro cc lbt.
