In the MU-MIMO downlink transmission introduced to IEEE802.11ac WLAN, the different transmission time of frames reduces the channel utilization efficiency. To solve this problem, the frame aggregation size selection has been proposed to align transmission times. However, assuming continuous traffic, limitations of the transmitted data increases the number of queuing packets and the latency. In this paper, we propose two kinds of dynamic frame aggregation size selection method: frame aggregation size selection by using nash bargaining solution and the average value of transmission time of frames. We show the improved throughput and latency by the proposed method.
