Abstract

estação base, terminal e método de comunicação. a presente invenção refere-se a uma estação base que controla adequadamente retransmissão em bandas não licenciadas. na estação base (100), uma unidade de transmissão (107) envia informação de controle pertencente a solicitações de retransmissão para sinais de resposta para dados de downlink e uma unidade de recepção (108) recebe sinais de resposta que foram retransmitidos com base na informação de controle. a informação de controle identifica um dentre uma pluralidade de valores candidatos pertencentes ao número de sinais de resposta solicitados para retransmissão. a pluralidade de valores candidatos é definida com base em qualquer uma de uma pluralidade de granularidades.
