  • Patent number: 10721030
    Abstract: A method and an apparatus for transmitting a reception acknowledgement for hybrid automatic repeat request (HARQ) of a user equipment (UE). The reception acknowledgement may be an ACK signal or a NACK signal for physical downlink shared channels (PDSCHs). The reception acknowledgement is transmitted on a physical uplink control channel (PUCCH), and the UE selects a resource of the PUCCH based on a number of the received physical downlink control channels. That is, the UE selects a first PUCCH resource for a number of the received PDCCHs being less than a pre-defined number, and the UE selects a second PUCCH resource for a number of the received PDCCHs being equal to or greater than the pre-defined number.
