Abstract

é discutido o manejo de transmissões de uplink por ues em componentes de portadoras não licenciados, no contexto de elaa 3gpp, acesso assistido licenciado avançado e, especificamente, a configuração pelo enób de lbt de várias portadoras, ouvir antes de falar. os sinais enób junto com o uplink concedem que o procedimento lbt seja utilizado antes de transmitir em uplink, seja um procedimento lbt curto, categoria 2, ou então um procedimento lbt categoria 4 mais longo. o enób sinaliza, para um específico componente de portadora, o mesmo procedimento de lbt que ele próprio utilizou para detectar e, então, proteger a portadora. além disso, quando ocorrem pausas durante a transmissão de uplink em canais compartilhados baseados em disputa envolvidos em comunicações do elaa, diversos procedimentos podem ser utilizados para restaurar as transmissões nos canais compartilhados baseados em disputa no uplink quando a ocupação do canal original foi reservada por uma estação base.
