Is LTE-Advanced really advanced?

NOMS 2016 - 2016 IEEE/IFIP Network Operations and Management Symposium, 2016
LTE-Advanced (LTE-A) theoretically can provide better network performance than 4G LTE. Mobile carriers around the globe are eager to deploy LTE-A to attract more subscribers. However, is it really making difference to the user experience compared to the existing LTE service?

LTE-Advanced Pro

2019
Le réseau de mobiles 5G a défini trois grandes catégories d’usages : les smartphones larges bandes (eMBB), la densification d’objets connectés (mMTC) et les applications critiques (URLLC). Cet ouvrage analyse l’évolution LTE (Long Term Evolution)-Advanced Pro du réseau de mobiles 4G permettant l’introduction de ces trois modèles de service.Il présente ...

Broadband radio access: LTE and LTE-advanced

2009 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2009
This paper addresses broadband radio access techniques for the Long-Term Evolution (LTE) specified as the Release 8 specifications (Rel. 8 LTE) and LTE-Advanced in the 3rd Generation Partnership Project (3GPP). We first briefly describe the system requirements for the Rel. 8 LTE and LTE-Advanced.

Dynamic transmission mode selection in LTE/LTE-Advanced system

2010 3rd International Symposium on Applied Sciences in Biomedical and Communication Technologies (ISABEL 2010), 2010
Recently, the LTE (Long Term Evolution) and LTE-Advanced systems, developed by the 3GPP (Third Generation Partnership Project), has been proposed as the candidate for the 4G systems (forth mobile communication systems). The combination of OFDM (orthogonal frequency division multiplexing) and MIMO (multiple-input multiple-output) transmission ...

LTE-Advanced: Heterogeneous networks

2010 European Wireless Conference (EW), 2010
Long-Term Evolution (LTE) allows operators to use new and wider spectrum and complements 3G networks with higher data rates, lower latency and a flat IP-based architecture. To further improve broadband user experience in a ubiquitous and cost effective manner, 3GPP has been working on various aspects in the framework of LTE Advanced.

LTE-Advanced coverage enhancements

IEEE Communications Magazine, 2014
Various technologies in LTE/LTE-Advanced have significantly improved the data throughput of 4G systems. However, the coverage of LTE networks, a very important performance metric to operators, receives relatively less attention. In this article we describe the motivations of LTE coverage enhancements from several aspects.

System performance of UTRA LTE and LTE-advanced

2011 International Conference on Communications, Computing and Control Applications (CCCA), 2011
The long term evolution of UMTS Terrestrial Radio Access (UTRA LTE) and its enhanced version - LTE-Advanced use OFDM (orthogonal frequency division multiplexing) combined with MIMO (multiple-input multiple-output), termed MIMO-OFDM. The spatial multiplexing (SM) MIMO scheme is deployed in LTE and LTE-Advanced downlink to provide high data rates.
