Industry-supported field trials are already demonstrating the viability of many of the technical concepts in LTE-Advanced. The approach is to increase data rates for all users, bring more out of small cells, dynamically adapt to network load and use of more carriers for more speeds. Also there will be unprecedented ecosystem of handset-manufacturer, software-developers and chip-designers that will support this intelligent network. In this presentation we will briefly discuss principle technologies that are being adopted in LTE-Advanced. We will understand the basics of the technologies that are under developmental stages and look if we can contribute to their future enhancements.

INTRODUCTION
• LTE Advanced is a mobile communication 4G standard
approved by International Telecommunications Union
(ITU) in Jan 2012 [1].
• Standardized by the 3rd Generation Partnership Project
(3GPP) as a major enhancement of the Long Term
Evolution (LTE) standard.
• It incorporates many enhancements including the
aggregation of multiple radio channels, advanced
antenna techniques, advanced network topology
and others.

LTE-Advanced Features
• Peak data rates: downlink - 1 Gbps; uplink - 500 Mbps.
• Spectrum efficiency: 3 times greater than LTE.
• Peak spectrum efficiency: downlink - 30 bps/Hz; uplink - 15 bps/Hz.
• Spectrum use: the ability to support scalable bandwidth use and spectrum
aggregation where non-contiguous spectrum needs to be used. the lower
and upper bandwidths limits are 40 MHz and 100 MHz.
• Latency: from Idle to Connected in less than 50 ms and then shorter than 5
ms one way for individual packet transmission.
• Cell edge user throughput to be twice that of LTE.
• Average user throughput to be 3 times that of LTE.
• Compatibility: LTE Advanced shall be capable of interworking with LTE and
3GPP legacy systems.

CONCLUSION
• Industry-supported field trials are already demonstrating the
viability of many of the technical concepts in LTE-Advanced.
• LTE-Advanced meets all 4G requirements and ITU officially
certified it as 4G.
• Nevertheless, the timing of LTE-Advanced deployment is
difficult to predict and will be dependent on industry demand
and the success of today’s Release 8 and 9 LTE rollouts.
