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.

  • 1. CHAITANYA chaitanya.singh87@gmail.com ABV-IIITM GwaliorThe Global 4GSolution
  • 2. chaitanya.singh87@gmail.com 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.
  • 3. chaitanya.singh87@gmail.com Evolutionary Trends Source of Figure : [2]
  • 4. chaitanya.singh87@gmail.com 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.
  • 5. chaitanya.singh87@gmail.com Principal technologies • SON ( Self-Optimizing Networks). • Carrier aggregation of contiguous and non-contiguous spectrum allocations. • Range expansion with Interference management and suppression • CoMP (Coordinated Multipoint transmission & reception). • Relaying. • Higher order MIMO. • Heterogeneous network support. • all-IP Flat Architecture.

  • 11. chaitanya.singh87@gmail.com 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.
