Technical overivew of 3GPP LTE

• 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 Rel-6 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. 3GPP
