- User equipment and a base station in a carrier aggregation system, and a call admission method thereof are discussed. The user equipment includes multiple physical layers, and the base station provides multiple component carriers. When messages for connection setup are transmitted and received between the user equipment and base station, the messages may include information about what component carriers are selected for the physical layers, information about what component carriers are selectable for the physical layers, information about calculations for uplink timing alignment. Call admission control and load balancing may be performed based on the information included in the messages. Accordingly, a carrier aggregation system providing call admission and load balancing is achieved.
