Robust resource allocation in multi-cell UE-specific RIS-assisted D2D relay networks under imperfect CSI
A robust multi-cell resource allocation (RMRA) framework for UE-RIS-assisted D2D relay networks under imperfect CSI is proposed, comprising distance-pruned Hungarian assignment, robust power control using Bernstein-type inequality and S-procedure based semidefinite programming, and soft actor-critic based passive beamf...
