3GPP EPS(Evolved Packet System)는 LTE, HSPA/HSPA+, Non-3GPP 네트워크 등 다양한 접속 네트워크를 지원하는 All-IP 기반 시스템이다. 최근에는 패킷 수준 QoS 프로필을 사용한 IP 흐름 지원이 EPS 요구 사항에 추가되었습니다. 본 논문에서는 EPS의 3G LTE 접속망에서 이러한 IP 흐름의 QoS를 지원하는 AMC(Adaptive Modulation and Coding) 방식을 제안한다. 제안 방식은 재전송을 QoS의 중요한 요소로 정의하고 서로 다른 최대 패킷 오류 확률을 적용합니다. P최대 AMC 전송 모드를 선택할 때 각 패킷에 적용됩니다. 결정하는데 있어서 P최대, QoS 제약 조건과 채널 상태를 고려하여 QoS 만족과 스펙트럼 효율성 극대화라는 두 가지 목표의 균형을 맞춥니다. 시뮬레이션을 통해 지연 위반과 재전송을 모두 줄이는 동시에 기존 방식에 비해 처리량을 향상시킬 수 있음을 보여줍니다.

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.
