In an aspect of the disclosure, a method, a computer-readable medium, and a wireless communication system including a control device and one or more cells are provided. The control device configures triggering conditions for a user equipment (UE) to initiate transmission of specific uplink (UL) reference signals for UL radio resource management (RRM) measurements. The one or more cells detect the specific UL reference signals transmitted by the UE on specific UL RRM resources based on a reference timing when the triggering conditions are met at the UE. The one or more cells measure the specific UL reference signals to obtain measurement results. The control device decides for a carrier change or a cell change based on the measurement results of the one or more cells. The control device indicates to the UE a set of selected cells or carriers for the UE to connect.
