“…In particular, the beam pattern of (4, 16, 1) is narrower than that of (4,8,2). Our simulation results are also consistent with both the current observation and the field measurement data for FD-MIMO in [3]. For the SU-MIMO, meanwhile, it has been shown that the average throughput with (4, 8, 2) is higher than that with (4,16,1).…”

“…A key technology in next-generation mobile communication systems is that of massive multiple input and multiple output (MIMO) or full-dimension (FD)-MIMO, where a base station or an evolved Node B (eNB) with a very large number of antenna elements serves a large number of user equipments (UEs) simultaneously on the same time-frequency resource set [1]- [3]. For downlink transmissions in a massive MIMO system, an eNB requires downlink channel state information (CSI) to perform beamforming for multiple UEs and to effectively nullify inter-user interference.…”

To implement high-order multiuser multiple input and multiple output (MU-MIMO) 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 experimental ground with which to optimize a CB-based MU-MIMO feedback scheme while identifying the design constraints for a massive MIMO system. Keywords: Massive MIMO, FD-MIMO, 3D-channel model, codebook-based feedback, system level simulation, interference-to-noise ratio, multiuser interference indicator, MUI, INR.

“…However, due to the increase in the number of antenna elements for MIMO applications, such as the massive MIMO and full dimension MIMO (FD-MIMO) [4,5] systems, the isolation between radiation elements becomes a key factor that will affect the MIMO's performance. The most direct way to reduce the coupling between ports is to increase the spacing between the elements.…”

Abstract-A multi-band antenna with omnidirectional radiation performance is proposed, which consists of 9 elements to form the structure of hexagonal prism. According to the placement rule, the antenna elements can be divided into two groups, one of which is placed in parallel on spaced three surfaces of the prism and the other placed vertically on the remaining spaced three faces of the prism. Each parallel element consists of two coplanar microstrip radiating patches which are nested within each other for miniaturization. Two parallel microstrips connected by a grounded disc with shorting pin are placed between the two patches to optimize the isolations. Each vertical element consists of two improved dipoles with four arms and a BALUN located at the back of the substrate plate which constitutes the quasi-Yagi structure. The resonant frequencies of the proposed prismatic antenna are 3.45 GHz, 4.9 GHz, 5.8 GHz and 15.2 GHz which can be used for low frequency bands of the fifth generation (5G) wireless communications and wireless local area networks (WLAN) as well as satellite communication applications.
