1. A method by a user equipment (UE), the method comprising:
- receiving an activation command for a secondary cell (SCell) from a base station in a subframe n;
performing a radio frequency (RF) bandwidth reconfiguration based on the activation command for the SCell; and
suspending data communication on a primary cell (PCell) for a predetermined number of subframes based on the activation command for the SCell,wherein the suspending of the data communication on the PCell begins in a subframe n+5.
