Abstract: An apparatus and a method for configuring a buffer descriptor suitable for packet aggregation are provided to improve QoS(Quality of Service) by selectively discarding a frame by TID(Traffic ID) because traffic of the same type has the same TID. A buffer stores packet data to be transmitted by frame units. An aggregation generator(405) divides position information of the packet data stored in the buffer by AC(Access Category) and TID to configure them in a bit map, and provides position information of packet data to be aggregated to an aggregation controller(403) according to aggregation conditions of the packet data. The aggregation controller(403) receives the position information of the packet data to be aggregated configured in the bit map which has been received from the aggregation generator(405), configures them to a single aggregation PSDU(PHY Service Data Unit), and transmits it to a destination.
