Abstract: In order to improve the throughput over WLAN, the IEEE 802.11ac standard, which has been used recently, introduces the frame aggregation and MU-MIMO (multi-user multiple-input and multiple-output) mechanisms. The frame aggregation concatenates multiple data frames in one MAC data unit. MU-MIMO provides SDMA (space division multiple access), which allows multiple STAs (stations) to share space resources. In an 802.11ac WLAN, MU-MIMO is used in the downlink data transfer in a way that data frames to multiple STAs are aggregated separately and transmitted at the same time. When traffic loads to individual STAs are different, however, it is possible that there is a waste in space and time resources. In order to avoid this waste, several methods to control the frame aggregation size for MU-MIMO are proposed. Those methods focus mainly on increasing the channel utilization, and so they have a problem that there is a large delay in transmitting an aggregated data unit. In this paper , we propose a new method to determine the frame aggregation size considering both channel utilization and delay data frames suffer from in transmission queues. A performance evaluation result shows that our method provides high channel efficiency with keeping transmission delay in a relatively small value. (More)
