O sistema de pacotes evoluídos 3GPP (EPS) é um sistema totalmente baseado em IP que suporta várias redes de acesso, como LTE, HSPA/HSPA+ e redes não 3GPP. Recentemente, o suporte de fluxos IP com perfis de QoS em nível de pacote foi adicionado aos requisitos do EPS. Este artigo propõe um esquema de modulação e codificação adaptativa (AMC) que suporta a QoS de tais fluxos IP na rede de acesso 3G LTE do EPS. Definindo a retransmissão como um fator crítico para QoS, o esquema proposto aplica diferentes probabilidades máximas de erro de pacote Pmax para cada pacote ao selecionar o modo de transmissão AMC. Em determinação Pmax, são consideradas as restrições de QoS, bem como as condições do canal, equilibrando dois objetivos: a satisfação da QoS e a maximização da eficiência espectral. Simulações mostram que ele é capaz de reduzir a violação de atraso e a retransmissão, ao mesmo tempo que melhora o rendimento em comparação com um esquema existente.

Abstract: 3GPP evolved packet system (EPS) is an all-IP based system that supports various access networks such as LTE, HSPA/HSPA+ and non-3GPP networks. Recently, the support of IP flows with packet level QoS profiles has been added to the requirements of the EPS. This paper proposes an adaptive modulation and coding (AMC) scheme that supports the QoS of such IP flows in the 3G LTE access network of the EPS. Defining the retransmission as a critical factor for QoS, the proposed scheme applies different maximum packet error probability Pmax to each packet when selecting the AMC transmission mode. In determining Pmax, the QoS constraints as well as channel condition are considered, balancing two objectives: the satisfaction of the QoS and the maximization of spectral efficiency. Simulations show that it is able to reduce both delay violation and retransmission, while improving throughput in comparison with an existing scheme.
