Apparatus and method for uplink cooperative transmission in a broadband wireless communication system

An apparatus and a method for uplink cooperative transmission in a broadband wireless communication system are provided to realize uplink data change by using channel of a terminal which is not use in communication of a base station. In an apparatus and a method for uplink cooperative transmission in a broadband wireless communication system, a base station selects a terminal performing an uplink cooperation transmission. A base station is allots a resource for uplink data change of terminal which is selected at a channel excluding a used channel for a down link. The terminal exchanges uplink data with a respondent through a channel excluding a channel for down link communication. The terminals performs uplink cooperation transmission according to MIMI(Multiple Input Multiple Output). A base station assigns a resources for the down link communications of the selected terminals to a different discontinuous time interval.
