If LTE network has deployed CA with 2 CC of 15 MHz, can a UE use CA with only 10 MHz on each CC? Can Network handle such scenario and just allocate 10 MHz for one UE? If possible, please share the related specs.
Resources allocation to UE depends on available resources, UE data requirement channel condition etc and scheduling algo. ENB allocate resources to in the for of PRB not bandwidth. So it may possible that eNB can allcate equal PRB from both cell or can have unequal resource allocation.
In carrier aggregation does aggregation of carrier happen from single eNB or multiple eNB? Is it possible to combine carrier of different eNB?
If only PCELL UL is configured and What is the use of TPC filed in Scell DL DCI?
How inter eNB carrier aggregation works in LTE ? How ue aggregate carrier from two different enb which messege ue receives? is it possible to perform carrier aggregation of two enB which are not connected using X2 interface ?
