What is cell edge and cell center UEs in LTE?

Question

While deploying or making lab setup what all things need to be taken into account ? In other words, how interference from neighboring cells can be minimized ? What all configuration values can create high interference between two LTE neighboring cells ?

Answer 1

There are some techniques to reduce the interference of the cell. One of the ICIC technique is SFR(soft frequency reuse). As per this technique all radio resources of eNodeB are divided in two part(cell center and cell edge). eNodeB allocate any one (either cell center or cell edge resource ) to UE. On the basis of allocated radio resources we can classify the UE as cell edge or cell center UE.

Comments

If ue is at cell centre it means it is having more resources if UE is at cell edge it is having less resources is it correct?

Total resources are divided in two parts between cell edge and cell center UEs. Suppose X radio resources are reserved for cell edge UEs and total radio resources - X will be available for cell center UEs. Any one of the radio resource would be shared among the UEs of that location.
