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.
