Query: Rate Maximizations for Reconfigurable Intelligent Surface-Aided Wireless
  Networks: A Unified Framework via Block Minorization-Maximization   The reconfigurable intelligent surface (RIS) has arose an upsurging research
interest recently due to its promising outlook in 5G-and-beyond wireless
networks. With the assistance of RIS, the wireless propagation environment is
no longer static and could be customized to support diverse service
requirements. In this paper, we will approach the rate maximization problems in
RIS-aided wireless networks by considering the beamforming and reflecting
design jointly. Three representative design problems from different system
settings are investigated based on a proposed unified algorithmic framework via
the block minorization-maximization (BMM) method. Extensions and
generalizations of the proposed framework in dealing with some other related
problems are further presented. Merits of the proposed algorithms are
demonstrated through numerical simulations in comparison with the
state-of-the-art methods.
