• Multiple access scheme– DL: OFDMA with CP.– UL: Single Carrier FDMA (SC-FDMA) with CP.

• Adaptive modulation and coding– DL/UL modulations: QPSK, 16QAM, and 64QAM– Convolutional code and turbo code

• Advanced MIMO spatial multiplexing techniques– (2 or 4)x(2 or 4) downlink and uplink supported.– Multi-user MIMO also supported.

• Support for both FDD and TDD• H-ARQ, mobility support, rate control, security, and etc.

LTE: Key Features

LTE –Advanced / 4G

Some of the key features of LTE-Advanced :Ø Worldwide functionality & roaming.

Ø High-quality mobile services.

Ø Compatibility of services within 3G & B3G and with fixed n/w.

Ø Interworking with other radio access systems.

Ø Enhanced peak data rates to support advanced services and applications (100 Mbit/s for high and 1Gbit/s for low mobility)

LTE-Advanced key technologies• Carrier aggregation.• Enhanced uplink multiple access.• Enhanced multiple antenna transmission.• Coordinated multipoint transmission and reception (CoMP).• Relaying.• Support for heterogeneous networks.• Self-optimizing networks (SON).• HNB and HeNB mobility enhancements.
