Abstract

"método e aparelho para reconhecimento em recepção ou em transmissão para uma em sistema de comunicação sem fio" a presente invenção refere-se a um método e um aparelho para reconhecimento em recepção ou em transmissão para uma harq (retransmissão automática híbrida) em um sistema de comunicação sem fio. um terminal recebe a informação sobre alocação de recursos downlink através de pelo menos um portador downlink entre os vários portadores downlink. além disso, o terminal recebe um bloco de transmissão downlink através de um canal compartilhado do downlink indicado pela alocação de recursos downlink. o terminal transmite um sinal ack/nack para o bloco de transmissão downlink através de um canal de controle uplink. se pelo menos um portador downlink é um portador primário, o canal de controle uplink utiliza um recurso primário. caso contrário, o canal de controle uplink utiliza um recurso secundário.
