Low-overhead millimeter wave beam training based on block-controlled reconfigurable intelligent surface

To address the issues of high overhead in channel state information acquisition and complex optimization of reflection phase shifts in large-scale reconfigurable intelligent surface (RIS)-assisted millimeter-wave communication systems, a low-overhead beam training scheme based on block-controlled RI...
