Abstract

Byline: Javier Gozalvez (1), John Dunlop (1) Keywords: Link Adaptation; updating periods; packet switched systems Abstract: Link Adaptation is an adaptive radio link technique that selects atransport mode, from a set of predefined modes of varyingrobustness, depending on the channel quality. One of theparameters that has to be defined when considering the applicationof Link Adaptation is the updating period which indicates howoften a decision is made on the transport mode to use. This paperanalyses the Link Adaptation performance for various updatingperiods under different operating conditions affecting the channelquality dynamics.

Abstract

Byline: Jeroen Wigard (1), Nina A.H. Madsen (1), Pablo Ameigeiras Gutierrez (2), Isaias Lopez Sepulveda (2), Preben Mogensen (2) Keywords: packet scheduling; Quality of Service; WCDMA; DSCH; DCH Abstract: This article focuses on the Quality of Service (QoS) achieved by packet scheduling. A packet scheduling algorithm, which can differentiate the QoS among user and service classes, is presented. The algorithm can be tuned from signal to interference ratio (C/I) based scheduling to Round Robin and beyond. Thus, an operator can choose between optimizing the spectral efficiency or giving a fair QoS distribution among the users within a user and traffic class. By combining the two effects, different strategies can be used for different user and service classes. Simulation results for the downlink shared channel (DSCH) are presented and implementation issues are also discussed.
