1. A method comprising:
determining, based on configuration information received from a network device via radio resource control (RRC) signaling, a first slot offset, a first list of slot offsets for a first resource set of an aperiodic-sounding reference signal (AP-SRS), and a second list of slot offsets for a second resource set of the AP-SRS, wherein a number of slot offsets in the first list of slot offsets is different from a number of slot offsets in the second list of slot offsets;
detecting downlink control information (DCI) received in a first slot;
determining, based on the DCI, a second slot offset from the first list of slot offsets;
determining a second slot based on the first slot, the first slot offset, and the second slot offset; and
generating the AP-SRS to be transmitted in the second slot.
