Abstract: The present disclosure provides sounding reference signal transmission and configuration methods, user equipment, and a network side device. The method for sounding reference signal (SRS) transmission includes receiving uplink resources of at least one cell from a network side device, where the uplink resources of each of the at least one cell comprise one or more SRS resource sets. The method further includes selecting, according to a predefined rule, at least one SRS resource set of each of the at least one cell for sending, when in a scenario in which an SRS switches between carriers for sending, where the scenario is configured by the network side device.
