A Novel Uplink Data Transmission Scheme For Small Packets In Massive MIMO System
, 2014 Intelligent terminals often produce a large number of data packets of small lengths. For these packets, it is inefficient to follow the conventional medium access control (MAC) protocols because they lead to poor utilization of service resources.

Improved Linear Precoding over Block Diagonalization in Multi-cell Cooperative Networks [PDF]
, 2012 In downlink multiuser multiple-input multiple-output (MIMO) systems, block diagonalization (BD) is a practical linear precoding scheme which achieves the same degrees of freedom (DoF) as the optimal linear/nonlinear precoding schemes.

Multi-Layer Downlink Precoding for Cloud-RAN Systems Using Full-Dimensional Massive MIMO
IEEE Access, 2018 Full-dimensional (FD) massive multiple-input multiple-output (MIMO) has recently emerged as one of the physical layer enablers of 5G systems. Grounded on prior work on layered precoding, a novel framework for low-complexity multi-layer downlink precoding
