Coexistence studies involving LTE-advanced

2010 3rd IEEE International Conference on Broadband Network and Multimedia Technology (IC-BNMT), 2010
With the introduction of new frequency bands and scenarios, the coexistence issue between an aggressor LTE-A system and a legacy system, operating in the same geographical area in adjacent channels, is becoming essential in RAN4 as a premise to enable the following standardization of LTE-A.

LTE-Advanced Uplink Transmissions

2016
In Long Term Evolution (LTE) uplink transmissions Single-Carrier Frequency Division Multiplexing (SC-FDM) is employed, mainly to achieve a lower Peak-to-Average Power Ratio (PAPR) at the transmitting mobile device, when compared to Orthogonal Frequency Division Multiplexing (OFDM) transmissions.

LTE-advanced: an operator perspective

IEEE Communications Magazine, 2012
LTE-Advanced extends the capabilities originally developed in LTE within the 3GPP. Carrier aggregationis the most significant, albeit complex, improvement provided by LTE-Advanced. Bandwidths from various portions of the spectrum are logically concatenated resulting in a virtual block of a much larger band, enabling increased data throughput ...

Carrier Aggregation in LTE-Advanced

2010 IEEE 71st Vehicular Technology Conference, 2010
UMTS LTE system can support flexible bandwidth configuration up to 20 MHz. Currently, system enhancements are being considered to provide substantial improvements to LTE and allow it to meet or exceed IMT-Advanced requirements. One key enhancement feature is bandwidth extension via carrier aggregation to support deployment bandwidth up to 100 MHz. This

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?

Heterogeneous networks in LTE-Advanced

2011 8th International Symposium on Wireless Communication Systems, 2011
3GPP 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 the broadband user experience in an ubiquitous and cost-effective manner, 3GPP has been working on various aspects of LTE-Advanced.

Multiple-antenna techniques in LTE-advanced

IEEE Communications Magazine, 2012
In this article we discuss the different multiple antenna techniques introduced in LTE-Advanced. Rather than describing the technical details of the adopted solutions, we approach the problem starting from the design targets and the antenna deployments prioritized by the operators. Then we present the main enabling solutions introduced for downlink and

Uplink Access Schemes for LTE-Advanced

IEICE Transactions on Communications, 2009
The 3GPP LTE-Advanced has been attracting much attention recently, where the channel bandwidth would be beyond the maximum bandwidth of LTE, 20MHz. In LTE, single carrier-frequency division multiple access (SC-FDMA) was accepted as the uplink access scheme due to its advantage of very low cubic metric (CM). For LTE-A wideband transmission, multicarrier
