Abstract: PURPOSE: A method for executing direct communication between terminals is provided to change resources for the interference and operation of a green filed mode and infrastructure mode by simultaneously using a wide band and a narrow band. CONSTITUTION: A transmission terminal transmits a contention message including a multicast group ID(Identity) and resource allocation information through a contention channel(S1600). The transmission terminal acquires multicast dedicated resources on a dedicated channel(S1610). The transmission terminal transmits data through the acquired dedicated resources to a terminal corresponding to the multicast group ID in a multicast type or a broadcast type(S1620). The transmission terminal releases the dedicated resources(S1630).

Abstract: PURPOSE: A communication method using carrier switching in a wireless communication system supporting multi carriers is provided to switch different carriers, thereby operating a terminal without data and service delay or interruption. CONSTITUTION: A terminal transmits a switching request message indicating what E-MBS service is desired to base station(S410). The base station transmits a switching response message to a terminal(S420). The switching response message includes information about switching timing among carriers set in a terminal. The terminal switches a carrier from the second carrier to the first carrier by referring to a switching response message. The terminal receives data from the base station through the first carrier after the switching timing(S430).
