Abstract

A DownLink (DL) frame transmission/reception apparatus and method for adaptively generating a DL frame, in which Multiple Input Multiple Output (MIMO) and Hybrid Automatic ReQuest (HARQ) are taken into consideration, and transmits the DL frame in a wireless communication system. A base station separately generates a DL frame for a Single Input Single Output (SISO) burst and a DL frame for a MIMO burst, or separates a zone for the SISO burst from a zone for the MIMO burst in one DL frame in a time domain, and transmits the DL frame. Accordingly, the terminal decodes only the SISO burst or MIMO burst corresponding to the terminal itself.
