LTE key fetures:-

• Scalable transmission bandwidth(up to 20 MHz)
• Improved Spectrum efficiency - DL spectrum efficiency should be 2-4 times Release 6 HSDPA
• UL spectrum efficiency should be 2-3 times Release 6 HSUPA
• Coverage - Good performance up to 5 km
• Mobility - Maintained mobility support up to 350 km/h (possibly up to 500 km/h)
• Advanced transmission schemes, multiple-antenna technologies
• Inter-working with existing 3G and non-3GPP systems
• Waveform - WaveformOFDM in Downlink and SC-FDM in Uplink
• Duplexingmode - FDD and TDD
• Modulation orders for data channels - QPSK, 16-QAM, 64-QAM
• MIMO support - SU-MIMO and MU-MIMO
