Abstract: Disclosed is a carrier management method in a carrier aggregation environment of a mobile communication system. A method for managing carrier status according to the present invention is configured to transmit a deactivation message for a subcarrier from a base station to a terminal, and change a subcarrier to a deactivated status when the deactivation message is transmitted after a predetermined amount of time elapses. The terminal receives the deactivation message transmitted and used by the base to change the subcarrier to the deactivated status when a predetermined amount of time elapses after the deactivation message is transmitted. At this point, a predetermined value may be used as the predetermined amount of time, in order to prevent the mismatch of status information on a corresponding subcarrier that the base station and the terminal manage. Accordingly, a mismatch of a subcarrier status that the base station and the terminal manage may be prevented during subcarrier deactivation by means of the method for managing carrier status according to the present invention. Therefore, problems resulting from the mismatch of a subcarrier status by the base station and the terminal may be prevented.

Abstract: The present invention relates to an apparatus and a method for constituting control information for at least one subframe allocation pattern for a multi-cast broadcast service. The method compares periods of radio frame units for each of subframe allocation patterns, sets up a unit period in which at least one subframe allocation pattern is repeated, and sets up control information containing subframe information allocated for a multi-cast broadcast service in the unit period set in the previous step. The method of the present invention enables, for example, efficient separation of MBSFN subframe for an MBMS from other MBSFN subframes.
