Claim 0:
1. A method for use in a user equipment (UE) operable to transmit a sounding reference signal (SRS) on a plurality of component carriers (CCs), the method comprising:
obtaining an indication to perform SRS carrier-based switching for at least one secondary cell (Scell) that operates on at least one CC of the plurality of CCs, wherein the at least one CC belongs to an unlicensed spectrum;
adapting at least one parameter for uplink transmit power control in response to the obtained indication, wherein the at least one parameter comprises a transmission gap length associated with the uplink transmit power control; and
transmitting an uplink signal using the adapted at least one parameter for the uplink power control while meeting at least one uplink power control requirement, wherein meeting the at least one uplink power control requirement comprises meeting an absolute power tolerance requirement when the transmission gap length is greater than 40 ms or meeting a relative power tolerance requirement when the transmission gap length is less than or equal to 40 ms.
