1. An apparatus comprising:
at least one processor; and
a non-transitory computer readable medium storing a program executable by the at least one processor, the program comprising instructions for:
receiving configuration information, wherein the configuration information comprises first uplink carrier information and second uplink carrier information, wherein the first uplink carrier information indicates that a first uplink carrier is a switching-from uplink carrier for a sounding reference signal (SRS) carrier switching, the second uplink carrier information indicates that a second uplink carrier is a switching-to uplink carrier for the SRS carrier switching, and the first uplink carrier belongs to a cell comprising a non-supplementary uplink (SUL) carrier and a SUL carrier, and wherein the first uplink carrier information comprises a cell index of the cell and further comprises an uplink carrier identifier, and the uplink carrier identifier indicates whether the switching-from uplink carrier is the non-SUL carrier or the SUL carrier; and
determining, based on the configuration information, the switching-from uplink carrier and the switching-to uplink carrier for the SRS carrier switching.
