Abstract

a programação uplink para sistemas de modo de acesso assistido por licença (laa) é discutida em que uma estação base transmite uma concessão condicional para os equipamentos de usuário (ues) servidos que incluem uma configuração de transmissão para transmissões uplink. a configuração de transmissão inclui os parâmetros necessários para o ue realizar transmissões. antes do início de uma oportunidade de transmissão uplink, uma estação base transmite uma concessão de ativação uplink através de uma portadora compartilhada baseada em disputa para os ues servidos. a concessão de ativação uplink indica a oportunidade de transmissão para os ues e pode identificar um subconjunto de ues dos ues servidos que estão disponíveis para transmissão. a estação base primeiro protege o canal antes de transmitir a concessão de ativação uplink. após a recepção da concessão de ativação uplink, os ues determinam se eles irão realizar transmissões uplink e, em caso afirmativo, transmitem os dados uplink de acordo com a configuração de transmissão.
