1. A method implemented at a terminal device, comprising:
receiving, from a network device, configuration information of a first Sounding Reference Signal (SRS) resource set and a second SRS resource set and the first SRS resource set being associated with a first Channel State Information-Reference Signal (CSI-RS) resource and the second SRS resource set being associated with a second CSI-RS resource;
receiving, from the network device, a first CSI-RS transmitted via a first Transmission and Reception Point (TRP) over the first CSI-RS resource and a second CSI-RS transmitted via a second TRP over the second CSI-RS resource,
determining, first precoding information for a first SRS based on the first CSI-RS and second precoding information for a second SRS based on the second CSI-RS;
transmitting, to the network device, the first SRS based on the first precoding information via the first TRP and the second SRS based on the second precoding information via the second TRP; and
transmitting, to the network device, at least one first Physical Uplink Shared Channel (PUSCH) based on the first SRS resource set and at least one second PUSCH based on the second SRS resource set in a case where an indication that the first SRS resource set and the second SRS resource set are to be used for at least one PUSCH is received by the terminal device.
