Sistem paket berkembang (EPS) 3GPP ialah sistem berasaskan semua IP yang menyokong pelbagai rangkaian capaian seperti rangkaian LTE, HSPA/HSPA+ dan bukan 3GPP. Baru-baru ini, sokongan aliran IP dengan profil QoS tahap paket telah ditambah kepada keperluan EPS. Makalah ini mencadangkan skema modulasi dan pengekodan adaptif (AMC) yang menyokong QoS aliran IP tersebut dalam rangkaian capaian 3G LTE EPS. Mentakrifkan penghantaran semula sebagai faktor kritikal untuk QoS, skema yang dicadangkan menggunakan kebarangkalian ralat paket maksimum yang berbeza Pmaks kepada setiap paket apabila memilih mod penghantaran AMC. Dalam menentukan Pmaks, kekangan QoS serta keadaan saluran dipertimbangkan, mengimbangi dua objektif: kepuasan QoS dan memaksimumkan kecekapan spektrum. Simulasi menunjukkan bahawa ia mampu mengurangkan kedua-dua pelanggaran kelewatan dan penghantaran semula, sambil meningkatkan daya pengeluaran berbanding dengan skim sedia ada.

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.
