Aperiodic SRS triggering mechanism enhancement

A method for a network device, comprising:

• generating configuration information for transmission to a user equipment (UE), wherein the configuration information indicates a first resource set for an aperiodic Sounding Reference Signal (AP-SRS), and wherein the first resource set for the AP-SRS comprises a first list of slot offsets;
• generating first control information for transmission to the UE, wherein the first control information activates a subset of the first list of slot offsets;
• generating second control information for transmission to the UE, wherein the second control information indicates a reference slot and a first slot offset from the subset of the first list of slot offsets;
• and
• obtaining the AP-SRS from the UE, wherein the AP-SRS is transmitted based on the reference slot and the first slot offset.

One or more non-transitory, computer-readable media having instructions that, when executed, cause a network device to:

• transmit, to a user equipment (UE), configuration information that indicates a first resource set and a second resource set for an aperiodic Sounding Reference Signal (AP-SRS), and wherein the first and second resource sets are mapped to a same trigger state for the AP-SRS, the first resource set for the AP-SRS includes a first list of slot offsets, the second resource set for the AP-SRS includes a second list of slot offsets, and a number of slot offsets in the first list of slot offsets is different from a number of slot offsets of the second list of slot offsets;
• transmit, to the UE, control information to indicate a reference slot and a first slot offset of the first list of slot offsets;
• and
• receive, from the UE, the AP-SRS.
