1. A method, comprising:
receiving from a network device, by a terminal device, a mapping relationship between a Sounding Reference Signal (SRS) resource group and a downlink reference signal through Radio Resource Control (RRC) signaling, wherein the mapping relationship comprises a state identifier, the state identifier identifying the mapping relationship between the SRS resource group and the downlink reference signal; and
receiving from the network device, by the terminal device, indication information, the indication information indicating the state identifier, the state identifier being configured to trigger the terminal device to transmit an SRS with the mapping relationship identified by the state identifier to the network device,
wherein receiving from the network device, by the terminal device, the mapping relationship between the SRS resource group and the downlink reference signal further comprises:
receiving from the network device, by the terminal device, configuration information of the SRS resource group, the configuration information of the SRS resource group comprising at least one indication field indicating the downlink reference signal corresponding to SRS resources in the SRS resource group,
the at least one indication field indicating an identifier of the downlink reference signal or indicating configuration information of the downlink reference signal,
wherein the downlink reference signal comprises at least one of a channel state information-reference signal (CSI-RS) or a synchronization signal block (SSB), and
wherein the SRS comprises at least one of an aperiodic SRS, a periodic SRS, or a semi-persistent SRS.
