Enhanced BlockACK method for A‐MPDU transmission in IEEE 802.11n/ac/ad WLANs. Issue 2 (1st January 2016) - Liu, Jilong
Abstract : An enhanced block acknowledgement (BlockACK) method for the aggregate MAC protocol data unit (A‐MPDU) transmission is proposed. In the proposed method, the position information of each aggregated subframe is carried by the A‐MPDU using the reserved bits and a novel position information control is used to acknowledge the A‐MPDU. By utilising the enhanced BlockACK method, the aggregation level of the A‐MPDU transmission will not be constrained by the effect of lost subframes. Theoretical analysis and simulation results demonstrate that the enhanced BlockACK method can achieve a more stable aggregation level and higher throughput than the conventional one.
