RECONFIGURATION OF ACTIVE COMPONENT CARRIER SET IN MULTI-CARRIER WIRELESS SYSTEMS RELATED APPLICATION

In a multi-carrier wireless system, a wireless mobile station comprising a control circuit. The control circuit is configured to receive first data according to a first configuration of two or more component carriers. The control circuit is further configured to receive signaling information indicating that a change of configuration to a second component-carrier configuration is pending, the change of configuration comprising a change in the number of component carriers to be used for data transmission or a change to a set of active component carriers, with the number of active component carriers remaining the same. The control circuit is further configured to selectively activate, de-activate, or reconfigure one or more transceiver components during a pre-determined guard interval of greater than one subframe, based on the signaling information. The control circuit is further configured to receive second data according to the second component-carrier configuration, after the guard interval.
