Abstract:
1. A method of configuring a carrier in a multi-carrier system, the method comprising: parsing received cell aggregation information in order to determine first cell information and second cell information; detecting a failure of a radio link of user equipment (UE) using a first cell of a plurality of aggregated cells, wherein the first cell of the plurality of aggregated cells is considered barred or not barred; and performing a radio resource control (RRC) connection reestablishment procedure using a second cell when the failure of the radio link of the UE is detected, wherein the second cell belongs to the plurality of aggregated cells when the first cell of the plurality of aggregated cells is considered not barred and the second cell does not belong to the plurality of aggregated cells when the first cell of the plurality of aggregated cells is considered barred, wherein detecting the failure of the radio link of the UE comprises comparing a determined number of in-synchronization states counted during a time period to a predetermined threshold, and wherein the time period starts upon detection of a first out-of-synchronization state and extends for a predetermined time.
