1. A method for a sounding reference signal (SRS) transmission switching process, comprising:
determining whether a colliding data transceiving is scheduled in one of a set of carriers at a same time as an SRS transmission switching process for an SRS transmission being scheduled in a current carrier in the set of carriers, wherein the set of carriers are activated for an electronic device, and wherein the colliding data transceiving has a higher priority than the SRS transmission; and
when no colliding data transceiving is determined to be scheduled in the set of carriers at the same time with the SRS transmission switching process,
determining a one or more SRS interruption slots during the SRS transmission switching process for a victim carrier that is to be interrupted by the SRS transmission switching process, wherein the SRS transmission switching process occupies the one or more colliding slots with a current numerology on the current carrier, and wherein the one or more SRS interruption slots are determined based on the numerology of the current carrier, and a numerology of the victim carrier, and wherein the victim carrier is in the set of carriers and different from the current carrier; and
transmitting the scheduled SRS transmission in the current carrier when no colliding data transceiving is determined.
