Content-Aware Cross Layer Optimisation for IMTAdvanced Systems

Abstract

Radio Resource Management (RRM) is crucial to properly handle the delivery of quality-of-service (QoS) in LTE systems. One of the techniques used for RRM in IMT-Advanced is cross layer optimisation (CLO) which normally involves the interaction between PHY and MAC layers before proper resource scheduling can be decided [1]. As the IMT-Advanced standard [2] only defines the PHY and MAC layers [3, 4], the effect of CLO is limited as the nature of the transmitted information is not taken into account.
