Abstract: Embodiments of the present disclosure provide a transmission method, a terminal, a network device, and a computer-readable storage medium. The transmission method may be performed by a terminal or a network device. The transmission method performed by the terminal includes sending at least one piece of control information by using a target uplink channel, where each piece of control information corresponds to Transmission Reception Point (TRP) identifier information, the TRP identifier information is used to determine a target TRP corresponding to the control information, and the target TRP is one TRP in multi-TRP transmission.

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.
