Carrier Aggregation Across Cell-Sites in 5G

One of the major features of 5G is carrier aggregation across cell-sites in 5G networks, which allows mobile network operators to combine a number of separate LTE carriers. This enables them to increase the peak user data rates and overall capacity of their networks and to exploit fragmented spectrum allocations.

In case of LTE Advanced, Carrier Aggregation can be applied to either the FDD or TDD variants of LTE and it can be used to combine carriers whether or not they are contiguous or even in the same frequency band. Ultimately, the aim is for Carrier Aggregation to combine up to five separate LTE carriers, each of up to 20MHz.

How Carrier aggregation across various cell sites take place in 5g, How Carrier aggregation across various cell sites take place in heterogeneous networks?

In heterogeneous site configurations, a Remote Radio Head can be used at the small cell with the macrocell eNB. In this case, the eNodeB may provide carrier aggregation functions for the carrier components from the macrocell and small cell.

In such cases, one scheduler controls both the macrocell and small cell resources in the network.
