Abstract

a presente invenção se refere a métodos, sistemas e dispositivos para comunicação sem fio. um dispositivo pode usar mecanismos de geração de relatórios para suportar a geração de relatórios aprimorados de informações de controle quanto ao espectro compartilhado. em alguns casos, um dispositivo pode utilizar portadoras componentes aprimoradas (eccs) para transmissões de dados. em um exemplo, o dispositivo pode transmitir informações de controle (por exemplo, ack / nack, csi, etc.) para um dispositivo correspondente usando uma transmissão isenta de cca (cet). em outro exemplo, um dispositivo pode reportar informações de controle quase periodicamente. por exemplo, a um dispositivo pode ser atribuído um intervalo especificado e uma janela de feedback de controle para reportar informações de controle (por exemplo, csi). a janela pode fornecer uma duração anterior e posterior ao intervalo especificado, durante a qual um ue pode transmitir informações de controle. por exemplo, o dispositivo pode executar uma cca, reservando o canal por uma duração que não inclui o intervalo específico, mas pode transmitir informações de feedback com base na determinação de que o intervalo especificado situa-se dentro da janela atribuída.
