Complexity Reduction in RIS Optimization: A User Grouping and Adaptive Beamforming Approach

This paper addresses a critical challenge of high computational complexity in the optimization of reconfigurable intelligent surfaces (RISs), a bottleneck that currently prevents real-time implementation in practical wireless networks. Existing iterative algorithms often exceed the channel coherence...
