Re-farming & New FDD Spectrum Allocation

High Flexibility To Implement LTE Re-farming In Real Networks

Huawei MSR enables the flexible spectrum sharing among multiple RATs (e.g. 2G & LTE)

Spectrum can be easily shared between 2G/3G and LTE according to voice/data traffic load or

operators strategy. It allows a smooth network evolution and an efficient services migration

In voice centric scenarios, the radio spectrum is assigned to 2G:

The whole BW for 2G

No BW for LTE

When data services become the main stream:

Less BW for 2G

BW for LTE

When LTE bears both voice/data services:

The whole BW is allocated to LTE

Edge RB being squeezed

Description: When available spectrum for LTE does

not match standard LTE carrier

bandwidths some Edge RB are

squeezed in DL and UL

DL: RB Suppression

UL: PUCCH over-provisioning

LTE carrier can fit into less bandwidth

without interference on adjacent

spectrum carriers

Benefit: To deploy LTE in any spectrum asset

To maximize the spectrum utilization
