  • Publication number: 20210184815
    Abstract: Methods and apparatus are provided in which data is received from a base station on a downlink data channel. It is determined whether a scheduling type of the downlink data channel is persistent or non-persistent. In case that the scheduling type is non-persistent, ACK/NACK information for the data is transmitted to the base station on a resource which is determined based on a first ACK/NACK resource allocation scheme. In case that the scheduling type is persistent and the data is initial persistent data, ACK/NACK information for the data is transmitted to the base station on a resource which is determined based on the first ACK/NACK resource allocation scheme. In case that the scheduling type is persistent and the data is persistent data following the initial persistent data, ACK/NACK information for the data is transmitted to the base station on a resource determined based on a second ACK/NACK resource allocation scheme.
