1. A method of a User Equipment (UE), wherein the UE is configured with one or more cells comprising a second cell, wherein the UE is configured to monitor one or more first UE-specific Physical Downlink Control Channels (PDCCHs) on the second cell, and wherein the one or more first UE-specific PDCCHs schedule data transmission on a first cell, the method comprising:
receiving, on the first cell, a Downlink Control Information (DCI) indicative of dormancy information associated with the one or more cells, wherein the DCI indicates dormant status of the second cell; and
responsive to the DCI indicating the dormant status of the second cell:
switching a scheduling cell of the first cell from the second cell on which the UE is configured to monitor the one or more first UE-specific PDCCHs to the first cell on which the one or more first UE-specific PDCCHs schedule data transmission; and
monitoring one or more second UE-specific PDCCHs on the first cell, wherein the one or more second UE-specific PDCCHs schedule data transmission on the first cell.
