1. A method for transmitting a sounding reference signal (SRS), comprising:
receiving time slot offsets for SRS resources or an SRS resource subset within an SRS resource set, wherein each of the time slot offsets indicates a position in time, relative to a receiving time slot of a downlink control information (DCI) when an SRS transmission is to be triggered;
receiving the DCI;
determining a length of a time interval for transmission of the SRS resources in the SRS resource set, wherein the length of time interval is equal to or smaller than a pre-determined value comprising at least one of a fixed value and a value reported in a capability signaling, and wherein the length of the time interval is a difference between a largest time slot offset among the SRS resources in the SRS resource set and a smallest time slot offset among the SRS resources in the SRS resource set; and
transmitting each SRS resource in the SRS resource subset or in the SRS resource set at a time corresponding to the time slot offsets based on the determined length of the time interval.
