Abstract: A method and an apparatus for processing a reception data frame are provided to improve data processing efficiency by minimizing an aggregated frame rearrangement delay. A bitmap processor(110) generates a bitmap of input frames. The bitmap includes a bit indicating a reception state of data frames, and at least one bit arranged in an order corresponding to frame sequence information of the input frame. A rearrangement processor(130) rearranges the bitmap corresponding to the frame sequence information, when at least one non-received data frame is included in a retransmitted input frame. A controller(150) sequentially detects bit values of all bits in the bitmap and delivers the data frame corresponding to at least two bits having a value of a first bit and a value of a second bit equal to or adjacent to the first bit to an upper layer, when the detected bit value has the first value.
