Abstract

The fifth generation of mobile networks (5G) seeks to expand and optimize connections across the entire network, meeting applications with demanding requirements, such as high throughput, low delay and high reliability. Bandwidth management techniques, which are used to improve the useful rate and enable a more robust transmission, are essential to meet some of these applications. Considering such importance, this study aims to present a performance analysis of the bandwidth resource management technique called carrier aggregation (CA). Using the ns-3 5G-LENA simulator, an evaluation of contiguous and non-contiguous CA in 5G New Radio (NR) is performed in different frequency bands, in a scenario \textit{indoor} defined by 3GPP, varying from the rate of offered and the distance between UE and gNB. The chosen frequency band in the combination of carriers exerts a lot of influence on the results, the non-contiguous CA may or may not have a better performance in relation to the contiguous CA, depending on which how often aggregation is done.
