Title: “Precoding and Resource Allocation for Rate-Splitting-Based Multiple-Antenna Systems in 6G Networks“
Abstract: In this presentation, we will examine precoding and resource allocation techniques for the downlink of rate-splitting-based multiple-antenna systems that are suitable for the sixth generation (6G) wireless networks. In particular, linear and nonlinear precoding strategies will be detailed along with stream combining strategies that are fundamental for the deployment of multiple antennas at user terminals and for improving the sum-rate performance of systems. We will also present power allocation approaches suitable for rate-splitting-based systems, which are based on exhaustive search strategies and efficient stochastic gradient-based learning algorithms. Results of rate-splitting-based multiple-antenna networks with co-located base stations and cell-free schemes will be presented and discussed along with future research directions.
