The rapid development of the Internet of Things (IoT) and the exponential diffusion of powerful multimedia devices are drastically creating the need for a new wireless communication technology referred to as 6G. Respect to the actual network, this new type of technology will allow higher density of connected devices, as well as higher user-data rate and sub-millisecond level end-to-end latency. As result, we will assist to a new scenario in which the deployment of both real-time (RT) and near-RT services like machine-to-machine (M2M), autonomous driving, vehicle-to-vehicle (V2V) communication, will be supported. In this view, several innovative radio access technologies (RAT), such as massive-MIMO, non-orthogonal multiple access (NOMA), spatial beamforming and the concept of relay networks have been proposed as key-enabling technologies for future networks. However, the deployment of these new RAT technologies represent a very challenging task. In particular, the implementation of algorithms and intelligent optimization frameworks able to ensure low-latency communication using these new types of RAT technologies will result crucial, especially when large number of users need to be served.
Future wireless networks are required to serve a wide range of wireless devices with stringent end-to-end delay requirements. This represents a very important challenge since most of the network resources are required for signalling, channel coding and redundancy, which are likely to result in increased latency. Then, optimisation schemes aimed to manage these two opposing features will represent very important tools to perform resource allocation and management in future wireless networks. However, these schemes result in large-scale nonlinear optimisation problems for which no solutions exist. Under these perspectives, the main objectives of this DTP project will be the definition of new optimization approaches and artificial intelligence/machine learning (AI/ML) driven frameworks aimed to support ultra-reliable and near zero-latency communications (URNZLC) for a large number of users. These represent very innovative and challenging research activities which are attracting the interest of both academic and industrial sectors.
The successful candidate will be part of a vigorous research team and find all the support and technical help in order to pursue her/his research activities. In particular, her/his main activities will include:
•Acquisition of deep knowledge and understanding of cutting-edge technologies for future wireless access networks, as well as the relevant network key performance indicators (KPI) used for performing network resource management, i.e. load balancing, user scheduling, bandwidth assignment, and transmitting power allocation;
•Definition of challenging large scale optimisation problems aimed to increase network performances by guaranteeing ultra-reliable and near zero-latency communications;
•Investigation of the most relevant and contemporary techniques which will permit to propose and evaluate innovative AI/ML based frameworks able to meet the requirements of the defined URNZLC optimisation problems.
