  • Publication number: 20200382244
    Abstract: A communication method and a communications device are disclosed. A first device in a communications system separately sends, to a second device, responses used to indicate a transmission result of target data: a first response and a second response. An indication manner of the first response is different from an indication manner of the second response. This approach can improve flexibility of a response indication manner. Therefore, the communications system can flexibly adjust indication manners of responses sent at different times to ensure indication precision of the responses while reducing transmission resources of the responses.
