A Survey of Resource Management Toward 5G Radio Access Networks

摘要: The next generation 5G radio access network (RAN) system is believed to be a true world wide wireless web (WWWW). This because such system will seamlessly and ubiquitously connect everything, support at least 1000-fold traffic volumes, 100 billion connected devices, diversified use cases as well quality of service (QoS) requirements (e.g., reliability, latency, data rates, coverage, security, privacy) multimedia applications by 2020. Recently, number research challenges including the explosive growth in mobile unprecedented have been identified for RAN systems. In addition, specific technologies multitier communication, massive MIMOs, mmWave backhauling, extreme densifications nodes (UDNs), full-duplex communications (FDCs), energy harvesting techniques emerged literature resolve some these However, activities defining technical advancements systems are yet continue half decade before specifications standardization commercialization concluded. Motivated limited existing surveys broader perspective (i.e., interference, spectrum-efficient, energy-efficient management schemes), this paper seeks take stock state-of-the-art (SOTA) on developments. Our attention focuses on relevant interference resource (RIRM) schemes that proposed last five years. contribution lies analysis, synthesis, summarized alignments conventional RIRM schemes toward overcoming $5G$ Finally, review highlights open issues deduced from recently schemes.
