1. A processor of a user equipment (UE) configured to perform operations comprising:
receiving, from a network, one or more first messages for triggering an aperiodic sounding reference signal (SRS) transmission, the one or more first messages indicating at least one SRS resource set including at least one of the following:
a first resource set of the at least one SRS resource set, being at least partially overlapping with a second resource set of the at least one SRS resource set, or a third resource set of the at least one SRS resource set, being configured with a timing offset smaller than a timing offset threshold; and
performing, with the network, the aperiodic SRS transmission based on the one or more first messages, wherein the aperiodic SRS transmission comprises dropping at least part of resources included in the first and second resource sets in accordance with a determination that the first and second resource sets are indicated by a same first message of the one or more first messages.
