Best answer

Carrier aggregation technology uses different channels and aggregate them to get higher throughput.
These different channels could be in same frequency band or in different frequency bands. Two overlapping cells geographically are not configured for same frequency since it results interference. Due to interference cell performance would degrade and user experience would be bad.

An UE configured for carrier aggregation, may have different radio channel conditions for primary and secondary cells.
I meant to say, primary cell may have strong signal strength at the same time UE may observed secondary cell(s) not too good.
In this case, does the same modulation and coding schemes used for primary and secondary or may use different coding and modulation schemes for different channels for the same sub frame?
