<p>The present invention provides a method and a corresponding user equipment for supporting carrier aggregation. According to the present invention, the method comprises determining a random access RA on a secondary cell Scell of a secondary timing advance group sTAG fails so that confusion on uplink UL transmission Tx timing reference of the sTAG is caused; and either stopping or suspending UL Tx on all Scells of the sTAG, or taking a corresponding measure to continue the UL Tx on all Scells of the sTAG.</p> |
