Driving forces behind LTE
› Performance:
– Higher peak rates
– Higher bandwidth
– Designed for ”always on applications” from start
› Spectrum flexibility:
– Use of new, re-farmed or unused spectrum
– FDD and TDD
– Variable channel bandwidth
› Cost:
– No circuit switched domain
– Low OPEX
– Simpler operation with less to configure and higher degree of self configuration

Downlink
OFDM - Orthogonal Frequency Division Multiplexing
› Characteristics
– Orthogonal: Other carriers zero at sampling
point
– Large number of 15 kHz sub carriers
– Long symbol time
› Benefits
– Spectrum flexibility
› Frequency diversity & flexible BW
– Robust against ISI
– Cost effective for wide carriers
– Well established

Uplink
SC-FDMA – Single Carrier FDMA (DFTS-OFDM)
› Similar to OFDM
– 15 kHz tones BUT consecutive
– Same time-domain structure
› Low Peak-to-Average Power Ratio
– Lower terminal cost and improved battery life
frequency
SC-FDMA enables low PAPR that gives more than 4 dB better link budget and reduced power
