Esquemas de escalonamento Qos-aware para enlace Uplink LTE-A em cenário de tráfego misto e redes heterogêneas

LTE-A networks have been developed to support a diversity of data traffic at high rates, especially to meet the requirements of applications such as video calls. This paper proposes a resource allocation scheme that prioritizes video call traffic in a heterogeneous network environment, with the presence of relay nodes. The results of the simulations demonstrated that the proposed allocation scheme can achieve better performance in terms of throughput and thus meet this requirement of video call applications.
