  • Overview of Full-Dimension MIMO in LTE-Advanced Pro
    Overview of Full-Dimension MIMO in LTE-Advanced Pro Hyoungju Ji, Younsun Kim, and Juho Lee, Samsung Electronics, Korea Eko Onggosanusi, Younghan Nam, and Jianzhong Zhang, Samsung Research America Byungju Lee, Purdue University Byonghyo Shim, Seoul National University Abstract Multiple-input multiple-output (MIMO) systems with a large number of basestation antennas, often called massive MIMO, have received much attention in academia and industry as a means to improve the spectral efficiency, energy efficiency, and processing complexity of next generation cellular system. Mobile communication industry has initiated a feasibility study of massive MIMO systems to meet the increasing demand of future wireless systems. Field trials of the proof-of-concept systems have demonstrated the potential gain of the Full-Dimension MIMO (FD-MIMO), an official name for the MIMO enhancement in 3rd generation partnership project (3GPP). 3GPP initiated standardization activity for the seamless integration of this technology into current 4G LTE systems. In this article, we provide an overview of the FD-MIMO system, with emphasis on the discussion and debate conducted on the standardization process of Release 13. We present key features for FD-MIMO systems, a summary of the major issues for the standardization and practical system design, and performance evaluations for arXiv:1601.00019v4 [cs.IT] 10 Aug 2016 typical FD-MIMO scenarios.

  • The-Lte-Standard.Pdf
    THE LTE STANDARD Developed by a global community to support paired and unpaired spectrum deployments April 2014 Prepared by Signals Research Group www.signalsresearch.com Project commissioned by Ericsson and Qualcomm Signals Research Group conducted a comprehensive review of the 3GPP standardization process and the underlying specifications that define LTE. The analysis sought to identify and quantify the similarities and differences within the overarching LTE specification documents as they pertain to the implementation require- ments for specific frequency bands, with a particular focus on paired (FDD) and unpaired (TDD) spectrum. This whitepaper provides the findings from that study, including the results from our review of nearly 83,000 3GPP submissions, which demonstrate that the overwhelming majority of submissions occurring during a six-year period apply to both LTE duplex schemes and that companies from all over the globe supported and contributed to the modest number of submissions which were more specific to LTE operating in paired or unpaired spectrum. As the sole authors of this paper, we stand fully behind the analyses and opinions that are presented in this paper. In addition to providing consulting services on wireless-related topics, Signals Research Group is the publisher of the Signals Ahead research newsletter. The views and opinions expressed in this paper may not reflect the views and opinions of Ericsson and Qualcomm. The LTE STANDARD Developed by a global community to support paired and unpaired spectrum deployments www.signalsresearch.com 1.0 Executive Summary Signals Research Group (SRG) conducted an exhaustive analysis of the 3GPP standardization process that led to the development of LTE, and we reviewed all of the primary specifications that define the LTE standard.

  • Integrating Wi-Fi Rans Into the Mobile Packet Core ENABLING the VISION of HETEROGENEOUS NETWORKING THROUGH the CONVERGENCE of WI-FI and 3G/LTE TECHNOLOGY
    white paper Integrating Wi-Fi RANs into the Mobile Packet Core ENABLING THE VISION OF HETEROGENEOUS NETWORKING THROUGH THE CONVERGENCE OF WI-FI AND 3G/LTE TECHNOLOGY Introduction There has been a great deal of interest of late in using Wi-Fi to offload traffic from heavily congested mobile networks. Early deployments consisted of building a parallel Wi-Fi offload network that takes traffic directly to the Internet. The mobile network operator would implement a proprietary client of some kind that would manage the offload function. Many subscribers have implemented their own offload strategy by selecting Wi-Fi when it’s available. Now the industry is shifting its focus toward integrating Wi-Fi RANs into the mobile packet core. In this approach, Wi-Fi would take its place alongside 3G/LTE as a cornerstone technology in the mobile world. The mobile device selects the best radio access technology based on the conditions (typically signal strength, application type, default to Wi-Fi, etc.) and the subscriber is automatically authenticated and connected. This is a manual process today, but the industry is moving rapidly toward automating all this under a combination of operator and subscriber control. All RAN traffic is brought back into the mobile packet core, and from there it goes to the mobile operator’s service complex, the Internet, or a corporate intranet. To make this HetNet vision a reality, the experience of connecting to Wi-Fi must be made as simple and secure as when connecting to cellular. The services must also be the same, and it should even be possible to seamlessly handoff between Wi-Fi and cellular RAN technologies.
