Higher data rates: Obviously this is a general requirement requested from any new system.

Quality of service, Lower delay: To enable true convergence between real-time and non-real-time services quality of service awareness is of absolute importance. This must already be paid attention to during the design of the physical layer. So LTE/EPC will be QoS aware from the very beginning on and not have QoS as an add-on, which is usually not very efficient.

LTE Speed

Expected New Spectrum allocation: It is expected to get some new frequency bands assigned to 3G. LTE should be ready to use these bands.

Flexible Bandwidth usage: LTE should be able to deal with frequency bands of different size. So a fixed bandwidth ultra-wideband system is not of big use. Rather LTE should be able to scale the frequency requirements dependent on the operator’s choice.

Reduced Terminal Complexity: 3G terminals are very complex and thus suffer often from poor performance due to hardware limitations and very often also software limitations (or bugs). LTE terminals should have essentially lower
complexity. This would also offer the possibility to implement other performance enhancement techniques later on.
These points result in a long list of requirements for LTE/EPC. So 3GPP/ETSI demand to have downlink bit rates of greater than 100 Mbps and uplink bit rates of 50 Mbps. Of high importance is also to increase the cell edge bit rates compared to HSPA.
