The present invention relates to a method for adjusting aggregation size based on Acknowledgement (ACK) bitmap, characterized by the steps of: receiving kCompressed Block Acknowledgement (CBA); calculating granularity factor (g) by applying Equation (1); determining bit error density (BED) for kCBA by applying Equation (2); receiving (k+1)CBA; determining bit error density (BED) for (k+1)CBA by applying Equation (2); adjusting the aggregation size based on the value of granularity factor (g), kbit error density BEDvalues and (k+1)bit error density BED; wherein if the kbit error density BEDis greater than the (k+1)bit error density BED, then increasing the aggregation size based on the value of granularity factor (g); wherein if the kbit error density BEOis lower than the (k+1)bit error density BEDthen decreasing the aggregation size based on the value of granularity factor (g); wherein if the kbit error density BEDis equal to the (k+1)bit error density BEDthen the aggregation size is kept unchanged.
