Throughput evaluation in LTE-Advanced network access using carrier aggregation

Abstract

This paper proposes throughput evaluation for LTE-Advanced network access in the particular service area employing carrier aggregation (CA) technique. From several kind of CA, we evaluate which one the best CA configuration in term of network throughput. 30 MHz aggregated bandwidth and two component carrier (CC) serve as a primary serving cell (PCell) and secondary serving cell (SCell) are used in the simulation. Simulation results show that the configuration of wider PCell bandwidth resulting better performance of the throughput. In particular, in CA intra-band scenario, the throughput of non-contiguous CA has better performance compared with CA contiguous. Whereas in the inter-band CA scenario, CC combination with lower frequency resulting better throughput performance.
