The Enhanced Distributed Channel Access (EDCA) mechanism is the most commonly implemented medium access scheme in today's wireless local area network (WLAN) products. With the introduction of the downlink multi-user MIMO (DL MU-MIMO) technology to the current IEEE 802.11 specification, the EDCA mechanism has been enhanced accordingly to support multiple simultaneous transmissions to different stations. In this paper, we report the work the IEEE 802.11ac task group has done for enhancing the… CONTINUE READING
