Abstract: Provided is a method and apparatus for efficient aggregation scheduling in a wireless local area network (WLAN) system, the apparatus including a delay setting unit to set a required delay time for each access category (AC), a storing unit to store a traffic identification (TID) of a packet in a queue of a corresponding AC when the packet arrives, a delay time calculator to calculate a maximum delay time predicted when the packet arriving at the queue is configured to be an A-MPDU and the configured A-MPDU is transmitted, and an A-MPDU configuring unit to compare the calculated maximum delay time and the required delay time, and configure a corresponding A-MPDU when the calculated maximum delay time is greater than the required delay time.
