Asymmetric Carrier Aggregation on Lte-Advanced Access Networks

Abstract

LTE-Advanced can improve the network capacity by combining some component carriers using asymmetric carrier aggregation. The aggregation can meet the requirements of the broadband traffics that tend to be asymmetric. The effect of using asymmetric carrier agrregation is analysed by exploring the coverage and throughput in the uplink and downlink. The analysis shows that 91% areas have been reached and the produced throughputs in the downlink are 236.836 Mbps (bandwidth 30 MHz), 404.985 Mbps (bandwidth 50 MHz), and 489.399 Mbps (bandiwtdh 60 MHz) while in the uplink are 40.823 Mbps (bandwidth 20 MHz), 40.872 Mbps (bandwidth 30 MHz), and 84.331 Mbps (bandwidth 40 MHz). In the other words, the larger bandwidth, the larger throughput that will be produced.
