摘要

This new millennium has been regarded as the era of the digital wireless communications revolution. With the intention of meeting the demands of the current customers' services and bridging to the future digital network, namely 5G network, the duty of the radio resource management (RRM) to quantify different altitudes should be carried out in an effective mechanism for avoiding any potential waste of resources, power, and processing time.;Therefore, this research intends to study and investigate the resource management for downlink radio access network in LTE-A and 5G systems. Furthermore, the packet scheduling, minimizing power, and guaranteeing suitable fairness of radio resources consistent with the latest 3rd Generation Partnership Project (3GPP) documents, are considered as the potential topics to be discussed.;The main contribution of this work is to introduce new scheduling cross-layer optimization schemes that can be used for finding a middle ground between the energy efficiency and fairness for LTE-A and 5G networks. These novel schemes will be designed and tested for examining if they reach their goals.;This dissertation starts with clarifying the RRM schemes used in the literature for LTE-A and 5G systems. Then, a novel optimization model is proposed to overcome the weaknesses of the fairness of the current conventional schemes and improve energy efficiency for LTE-A network. Next, the bandwidth-expansion concept is considered as a possible solution to minimize the downlink transmitted power while maintain system throughput, where an optimization model is developed for utilizing the resource allocation of single-input-single-output (SISO) mode.;Subsequently, multiple input multiple output (MIMO) technique is considered for improving the spectral efficiency of LTE-A network.;On the other hand, the applicability of the developed optimization models in this work is not limited to the LTE-A system, where the issues how to derive the closed-form or exact expressions of the future 5G systems are investigated as well. In addition, challenging research topics are included for extending to more promise paradigms, such as networks densification, using femtocell under LTE-A cellular environment, elaborating relay nodes scheme to present new scenarios that could be used for enhancing the transmission for the 5G systems.
