Abstract

TRANSMISSÃO DE CONCESSÃO CONFIGURADA EM NOVO RÁDIO NÃO LICENCIADO (NR-U). São fornecidos sistemas de comunicações sem fio e métodos relacionados a transmissões configuradas em uma banda de radiofrequência compartilhada. Um equipamento de usuário (UE) recebe, a partir de uma estação base (BS), uma indicação de um primeiro recurso configurado em uma banda de radiofrequência compartilhada para uma comunicação em uma primeira direção. O UE recebe, a partir da BS, uma primeira configuração para selecionar entre uma validação da primeira direção ou a ausência de uma invalidação da primeira direção para usar o primeiro recurso configurado para a comunicação. O UE comunica, com a BS, a comunicação na primeira direção usando o primeiro recurso configurado com base na primeira configuração.
