Station and device for receiving aggregation frame in wireless lan system, method thereof

A receiving station for processing an aggregation frame of a wireless LAN, and a device and a method thereof are provided to transmit data at high speed by minimizing transmission delay of the data. A receiving device for processing an aggregation frame of a wireless LAN includes an aggregation frame reception processing unit, and an MPDU reception processing unit. The aggregation frame reception processing unit receives the aggregation frame, and extracts delimiter information effective in receiving the aggregation frame, wherein the delimeter information includes a length information of an MPDU(MAC Protocol Data Unit). The MPDU reception processing unit receives and processes the aggregation frame for each MPDU through the delimeter information.
