2013-06: LTE-A HetNets using Carrier Aggregation

LTE-Advanced standardisation in Release 10 was completed in early 2011 and commercial network deployments using first Release 10 features are likely to be announced later this year. One of the most attractive features of LTE-A is Carrier Aggregation, where a user equipment (UE) might be scheduled across multiple carriers. Besides this, Heterogeneous Networks (HetNet) using small cells gained a lot of interest recently due to their potential to increase network capacity. This white paper provides some insight into how LTE-A HetNets with or without a centralized architecture might be deployed today and in the future, in particular in combination with Carrier Aggregation.
