To achieve ever increasing demand for higher user throughput, 3rd Generation Partnership Project (3GPP) have introduced Carrier Aggregation (CA) feature in the Long-Term Evolution — Advanced (LTE-A) standard. Wherein, the CA feature widens the transmission bandwidth by aggregating multiple Component Carriers (CCs) to meet the demand for higher data rate. To the best of our knowledge, till now available...
Carrier Aggregation (CA) features will enhance Quality of Service (QoS) for the users as well as cell throughput of the LTE-Advanced (LTE-A) base-station (eNodeB). To deliver a high QoS for users, an eNodeB requires a well-designed and efficient CA enabled downlink scheduling algorithm. Enabling aggregation of multiple component carriers leads to huge power consumption compared with non-CA scenario...
An LTE-Advanced (LTE-A) Heterogeneous Network (HetNet) constitutes of a macro cell and small cells, where, the former acts as an overlay network and the latter as an underlay network. In HetNet, enabling Carrier Aggregation (CA) usually results in severe downlink interference at small cells from macro cell because of high powered transmissions from macro cell on over-lapping component carriers (co-channels)...
