3G LTE Requirements

Share

Spectrum efficiency 

DL : 3-4 times

UL : 2-3 times

Frequency Spectrum

Scalable bandwidth : 1.4, 3, 5, 10, 15, 20MHz

Advertisement

To cover all frequencies of IMT-2000: 450 MHz to 2.6 GHz

Peak data rate

DL : > 100Mb/s for 20MHz spectrum allocation

UL : > 50Mb/s for 20MHz spectrum allocation

Latency

C-plane : < 100ms to establish U-plane

Advertisement

U-plane : < 10ms from UE to server

Coverage

Performance targets up to 5km, slight degradation up to 30km

Mobility

LTE is optimized for low speeds 0-15km/h but

connection maintained for speeds up to 350 or 500km/h

Handover between 3G & 3G LTE

Real-time < 300ms

Non-real-time < 500ms

LTE is aimed at minimizing cost and power consumption while ensuring backward-compatibility and a cost effective migration from UMTS systems. Enhanced multicast services, enhanced support for end-to-end Quality of Service (QoS) and minimization of the number of options and redundant features in the architecture are also being targeted.
The spectral efficiency in the LTE DownLink (DL) will be 3 to 4 times of that of Release 6 HSDPA while in the UpLink (UL), it will be 2 to 3 times that of Release 6 HSUPA. The handover procedure within LTE is intended to minimize interruption time to less than that of circuit-switched handovers in 2G networks. Moreover the handovers to 2G/3G systems from LTE are designed to be seamless.
