内容記述
In recent years, advances in wireless local area network (WLAN) systems have led to large increases in the transmission speed. However, the transmission efficiency is decreased by the channel state information (CSI) estimation algorithm in the medium access control (MAC) sub-layer. The massive MIMO transmission has attracted attention as a new technology for wireless communication in 5th-generation mobile communication systems (5G). We propose a novel access control scheme for multi-beam massive MIMO technology called overhead-less ultra-high efficiency transmission scheme. The proposed scheme allows random access control without CSI estimation for massive MIMO technology. Thus, this scheme is greatly reduces the overhead of the MAC sub-layer and improves the transmission efficiency. The proposed scheme can be used to control new massive MIMO systems. We evaluated overhead-less ultra-high efficiency transmission scheme for multi-beam massive MIMO in WLAN systems.
