Abstract: This application discloses a communication method and apparatus. In the method, a terminal device receives first configuration information from an access network device, where the first configuration information is for configuring M configured grant (CG) resources to correspond N downlink reference signals. The M CG resources are used by the terminal device to send uplink information when the terminal device is in a non-connected state. The terminal device then receives first reconfiguration information from the access network device after the terminal device enters the non-connected state, where the first reconfiguration information is for updating downlink reference signals corresponding to some or all of the M CG resources.
