本节将总结LTE的基本参数：
| Parameters | Description |
|---|---|
| Frequency range | UMTS FDD bands and TDD bands defined in 36.101(v860) Table 5.5.1, given below |
| Duplexing | FDD, TDD, half-duplex FDD |
| Channel coding | Turbo code |
| Mobility | 350 km/h |
| Channel Bandwidth (MHz) |
|
| Transmission Bandwidth Configuration NRB : (1 resource block = 180kHz in 1ms TTI ) |
|
| Modulation Schemes |
UL: QPSK, 16QAM, 64QAM(optional) DL: QPSK, 16QAM, 64QAM |
| Multiple Access Schemes |
UL: SC-FDMA (Single Carrier Frequency Division Multiple Access) supports 50Mbps+ (20MHz spectrum) DL: OFDM (Orthogonal Frequency Division Multiple Access) supports 100Mbps+ (20MHz spectrum) |
| Multi-Antenna Technology |
UL: Multi-user collaborative MIMO DL: TxAA, spatial multiplexing, CDD ,max 4×4 array |
| Peak data rate in LTE |
UL: 75Mbps(20MHz bandwidth) DL: 150Mbps(UE Category 4, 2×2 MIMO, 20MHz bandwidth) DL: 300Mbps(UE category 5, 4×4 MIMO, 20MHz bandwidth) |
|
MIMO (Multiple Input Multiple Output) |
UL: 1 x 2, 1 x 4 DL: 2 x 2, 4 x 2, 4 x 4 |
| Coverage | 5 – 100km with slight degradation after 30km |
| QoS | E2E QOS allowing prioritization of different class of service |
| Latency | End-user latency < 10mS |
