The purpose of this amendment is to improve the IEEE 802.11(TM) wireless local area network (WLAN) user experience by providing significantly higher basic service set (BSS) throughput for existing WLAN application areas and to enable new market segments for operation below 6 GHz including distribution of multiple multimedia/data streams.
Space division multiple access (SDMA)-based medium access control (MAC) protocols have been proposed to enable concurrent communications and improve link throughput in multi-input-multi-output (MIMO) ad hoc networks. For the most part, the works appearing in the literature make idealized and simplifying assumptions about the underlying physical layer and some aspects of the link adaptation protocol...
In this paper, we design a new class of cross-layer opportunistic channel access scheduling framework for multiple-input multiple-output (MIMO) networks through exploitation of channel distribution information (CDI) in a form of full spatial correlation matrix. Due to propagation delay, infrequent channel updates, and time-varying node position, channel knowledge becomes outdated and scheduler based...
The emerging 802.11n standard establishes the integration of MIMO technology in WLANs with the goal of achieving high data rates. However there are still many open issues regarding MAC protocol design for MIMO based systems, especially in order to exploit the multiuser capabilities of the MIMO channel. In this paper we investigate practical solutions to implement multiuser downlink transmission in...
