Abstract: This application discloses a sounding reference signal (SRS) sending method, a resource configuration method, and a related device. It may be applied to a scenario where there is a discrepancy between uplink and downlink antenna structures of a terminal device. In the method, the terminal device sends a first SRS using a first SRS resource configured by a network device, and sends a second SRS using a second SRS resource configured by the network device, where a transmission beam of the first SRS resource is different from a transmission beam of the second SRS resource. This satisfies a requirement for measuring downlink channel state information in a scenario where there is a discrepancy between the uplink and downlink antenna structures of the terminal device. Consequently, downlink transmission weights can be calculated, thereby implementing SRS-based downlink transmission and increase cell-level or UE-level capacity.
