  • Publication number: 20230084145
    Abstract: A communication method and apparatus to reduce a waiting latency in a retransmission process. A terminal device receives a first PDSCH from a network device. In response to failing to decode data carried on the first PDSCH, the terminal device sends an SRS to the network device on a first time-frequency resource. In response to the network device not receiving feedback information of the first PDSCH, or receiving feedback information of the first PDSCH that is a NACK, the network device retransmits the first PDSCH based on a result of measuring the SRS. After determining that the first PDSCH fails to be decoded, the terminal device directly sends the SRS to the network device by using the first time-frequency resource.
