Pursuing the Potential of New Mechanisms for Performance Engineering of 5G

In this position paper, we provide a discussion of the need for new mechanisms towards optimizing the performance of the firth generation (5G) wireless systems, and then we outline on-going research work and results in this direction. Initially we go over the recently proposed concept of network anticipation and then resource allocation, since these two themes form the core of the ACT5G research project. Then, we discuss two specific topics within the project. The first is the use of stochastic modeling for millimeter wave (mmWave) systems, which are expected to be part of 5G networks. Our modeling enables network anticipation, resulting in an estimation of the coverage probability of mmWave, including coverage with non-line-of-sight (NLOS) mmWave beams. In the second research topic, we address the use of scalable and dynamic transmission time interval (TTI) for scenarios with a mix of different traffic types. In addition, and highlight the importance of optimizing the channel and TTI allocation in this context. Numerical results of these studies are presented and discussed. Finally, we outline directions for future study.Funding Agencies|European Union Horizon 2020 MSCA project ACT5G [643002]</p
