With the current rollout of 5G, the focus of the research community is shifting towards the design of the next generation of mobile systems, e.g., 6G mobile networks. Non-orthogonal multiple access (NOMA) has been recongized as an essential enabling technology for the forthcoming 6G networks to meet the heterogeneous demands on low latency, high reliability, massive connectivity, improved fairness, and high throughput. The principle of NOMA is to encourage users for spectrum sharing, where multiple users are served in the same resource block, such as a time slot, subcarrier, or spreading code. The aim of this talk is to provide an overview of the latest research results and innovations in NOMA technologies as well as their emerging applications, including machine learning, backscatter communications (BackCom), intelligent reflecting surfaces (IRS), mobile edge computing (MEC), etc. Future research challenges regarding NOMA in B5G and 6G are also presented.

The past decades have witnessed a growing development of distributed Machine Learning (ML) with its applications in various wireless services. As one of the key paradigms of distributed ML, Federated learning (FL) allows a group of end-devices to report their locally trained models to a central parameter-server for aggregating the global model, instead of directly sending the raw data to the central parameter-server, which thus brings the advantages of preserving the data privacy of the end-devices as well as saving the bandwidth consumption for delivering the raw data to the parameter-server. However, periodically executing the local model training as well as reporting the trained model-data to the parameter-server result in significant energy consumption to end-devices which usually suffer from limited energy capacities. To address this challenging issue, this talk will focus on the discussions on the design of green Federated Learning. In particular, we will leverage the recently advanced wireless power transfer to enable a sustainable and efficient federated learning and illustrate the joint optimization of wireless power transfer strategy, learning strategy, and resource allocations.
