Method for adjusting aggregation size based on acknowledgment (ACK) bitmap

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