“…O escalonamento de recursosé feito pela eNodeB para todas as UEs conectadas a ele, em intervalos de tempo denominados Transmission Time Interval (TTI), sendo esse intervalo de tempo o mesmo de um subquadro com duração de 1 ms [9]. No downlink a eNodeB analisa os endereços de destino dos pacotes em seu buffer de entrada, que devem ser encaminhados para as UEs na RAN.…”

Resumo-A popularização dos smartphones levou a um crescimento acentuado do tráfego de vídeo streaming em redes móveis, que jáé a principal aplicação da rede em termos de tráfego. O vídeo streaming demanda recursos de qualidade de serviço (QoS, quality of service) para seu correto funcionamento. Em sistemas Long-term Evolution (LTE) a qualidade de serviço depende do uso de métodos de escalonamento de recursos apropriados na rede rádio. Neste artigoé proposto um novo método de escalonamento de recursos para redes LTE com o objetivo de aumentar o número de usuários de vídeo streaming satisfeitos. Os resultados são comparados com algoritmos de escalonamento em uso atualmente. A avaliação de desempenho foi realizada através de simulações computacionais. Os resultados mostram que o uso do método proposto resulta em um aumento significativo do número médio de usuários de vídeo streaming satisfeitos, principalmente em situações de maior congestionamento. Palavras-Chave-LTE, escalonamento de recursos, redes móveis, vídeo streaming.

Abstract-Extensive research efforts are being attracted towards resource allocation in LTE networks. However, from the resource allocation perspectives, linear services such as Digital TV programs have been scarcely studied. In fact, for end-users requesting linear services, the maximization of the the number of users served is much important goal than maximizing the overall capacity of the network. In this paper, linear services oriented resource allocation strategy is proposed. The goal of the proposed algorithm is to maximize the success rate of the users, depending on a minimum required quality of service (QoS), measured in terms of user capacity constraint. The proposed method was tested and compared to the optimal branch and Cut solution and has shown good robustness against network and user parameters.

Resource allocation in LTE networks has attracted extensive research efforts. However, linear services (such as Digital TV programs) have been barely considered from the resource allocation perspectives. Indeed, when a linear service is offered to the end-users, the network should satisfy the maximum number of users served rather than maximizing the sum rate capacity. In this paper, linear services oriented resource allocation strategy is proposed. The proposed approach aims at maximizing the users' success rate, based on a minimum required quality of service (QoS) measured in terms of minimum throughput. The proposed method was tested in different scenarios and has shown great robustness against user density, user requirements and reuse factor.
