Apparatus and method for transmitting data and apparatus and method for receiving data of multi-carrier communication system

PURPOSE: A data source of a multi carrier transmission system and a method and data receiving method and apparatus thereof are a call connected of a terminal, transmission priority information of multi-carrier is transmitted from the base station with the terminal. In that way the waste of the radio resource is improved. CONSTITUTION: If transmitted-data is created, the BS(Base Station) at least assigns data according to a priority of multi-carrier among multi-carrier to one(S520). The base station transmits the down link map message through the main carrier with a MS(Mobile Station)(S530). The down link map message comprises the resource allocation information. In the terminal is the corresponding carrier wave by the resource allocation information, data is a message received successively according to the priority of multi-carrier(S540~S560).
