3GPP QoS-based scheduling framework for LTE Ameigeiras Gutiérrez, Pablo José Navarro Ortiz, Jorge Andrés-Maldonado, Pilar López Soler, Juan Manuel Lorca, Javier Pérez-Tarrero, Quiliano García Pérez, Raquel Long Term Evolution (LTE) Scheduling Guaranteed BIT Rate (GBR) Non-GBR Quality of Service (QoS) QoS Class Identifier Packet Delay Budget (PDB) This paper proposes the design of a scheduling framework for the downlink of the Long Term Evolution (LTE) system with the objective of meeting the Quality of Service (QoS) requirements as defined by the QoS architecture of the 3G Partnership Project (3GPP) specifications. We carry out a thorough review of 3GPP specifications analyzing the requirements of the 3GPP QoS architecture. LTE bearers may be associated with a Guaranteed Bit Rate (i.e., GBR bearers) or not (i.e., non-GBR bearers). Additionally, the specifications establish a Packet Delay Budget (PDB) to limit the maximum packet transfer delay. To achieve our goal, we design a channel-aware service discipline for GBR bearers which is able to fulfill not only the GBR but also the PDB. Additionally, we also design an algorithm for prioritizing GBR and non-GBR bearers from different QoS Class Identifiers (QCIs) following 3GPP QoS rules. We compare the proposed framework with two reference schedulers by means of network-level simulations. The results will show the ability of the proposed framework to address the QoS requirements from 3GPP specifications while providing an interesting performance from a spectral efficiency viewpoint. 2017-02-13T12:30:16Z 2017-02-13T12:30:16Z 2016 journal article Ameigeiras, P.; et al. 3GPP QoS-based scheduling framework for LTE.
