Beamforming (BF) is a key procedure to overcome propagation limits in millimeter-wave bands but also to extend network coverage in sub 6 GHz bands, as considered in recent 3GPP and IEEE communication standards. Up to date, ns-3 included various ideal BF methods, in which an ideal channel state acquisition is assumed and no BF overhead is considered. However, ns-3 lacks the implementation of realistic BF methods, in which the overhead needed to perform BF-related procedures and the errors due to a non-ideal channel state acquisition are taken into account. A way to perform realistic BF is to rely on Sounding Reference Signals (SRS) for channel estimation and then determine the best BF vectors based on the channel estimate. In this paper, we first present an abstraction model to perform BF using SRS-based channel estimation, and then we provide the implementation details of 5G New Radio (NR)-compliant SRSs and new realistic BF methods using SRS-based channel estimate, as included in the ns-3 5G-LENA simulator. Simulations are provided to compare realistic BF and ideal BF methods, for different propagation scenario conditions and SRS transmitted powers.

“…Além das análises que buscam mostrar o desempenho em diversos cenários do 5G NR, os artigos trazem também detalhes da implementação das funcionalidades do simulador, como o uso da CA e da multiplexação das numerologias. Há também trabalhos mais específicos da camada PHY do NR usando o ns-3, como [15] e [16], que incluem a implementação do canal espacial [15], seguindo a recomendação do 3GPP, e uma nova abstração da camada física para as simulações sistêmicas [16]. Para a camada MAC, os estudos presentes em [17] e [18] trazem o impacto dos escalonadores do 5G NR na taxa útil e no atraso para tráfegos em downlink e uplink.…”

Resumo-A quinta geração (5G) da rede de comunicação do 3GPP propõe uma variedade de casos de uso, que vão desde as comunicações móveis em banda larga melhoradas (eMBB), até comunicações ultra confiáveis e de baixíssimo atraso (URLLC), além das comunicações massivas entre máquinas (mMTC). Este trabalho apresenta uma análise de desempenho do uso da agregação de portadoras (CA) no sistema de comunicação 5G NR, utilizando o simulador de eventos discretos ns-3 5G-LENA. Para isso, foram feitas análises com bandas contíguas, considerando taxas oferecidas e distâncias diferentes.
