Abstract:
1. A method for operating a terminal for performing a carrier switching operation in a multicarrier system, the method comprising: establishing an E-MBS (enhanced-multicast and broadcast service) service connection with a base station; sending, to the base station, an E-MBS report message including connection information; receiving an E-MBS response message including unicast available interval information based upon the connection information from the base station in response to the E-MBS report message; and performing a carrier switching operation for receiving the E-MBS service based upon the unicast available interval information, wherein the unicast available interval information is represented by using a plurality of bits, wherein each of the plurality of bits indicates whether the terminal is available for E-MBS data scheduling in a primary carrier or a secondary carrier by a unit of frames, and wherein the E-MBS report message includes an E-MBS zone ID, a report mode, and an E-MBS connection bitmap, and the E-MBS connection bitmap represents at least one E-MBS service mapped in an ascending order according to a sum of an E-MBS ID and an FID value.
