Abstract
To implement high-order multiuser multiple input and multiple output (MU-MEMO) for massive MIMO systems, there must be a feedback scheme that can warrant its performance with a limited signaling overhead. The interference-to-noise ratio can be a basis for a novel form of Codebook (CB)-based. MU-MIMO feedback scheme. The objective of this paper is to verify such a scheme's performance under a practical system configuration with a 3D channel model in various radio environments. We evaluate the performance of various CB-based feedback schemes with different types of overhead reduction approaches, providing an a experimental ground with which to optimize a CB-based MU-MEMO feedback scheme while identifying the design constraints for a massive MIMO system.
