Claim 10:
11. A method for use in a network node operable to receive a sounding reference signal (SRS) on a plurality of component carriers (CCs), the method comprising:
sending, to a user equipment (UE), 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; and
receiving, from the UE, an uplink signal based on at least one parameter for uplink transmit power control adapted in response to the sent indication, wherein:
the at least one parameter for uplink transmit power control adapted in response to the sent indication comprises a transmission gap length associated with the uplink transmit power control; and
the uplink signal at least meets an absolute power tolerance requirement when the transmission gap length is greater than 40 ms or at least meets a relative power tolerance requirement when the transmission gap length is less than or equal to 40 ms.
