Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) and a base station may participate in a one-shot initial access procedure involving a reconfigurable intelligent surface (RIS) divided into a number of sub-RISs, each sub-RIS associated with a different configuration for reflecting signaling from the base station. In some aspects, the base station may configure each sub-RIS to have a different frequency shift and transmit, to the UE, a parameter indicating a quantity of synchronization rasters associated with each of a set of beams that the base station may use as part of the one-shot initial access procedure. The UE may, for each beam, monitor a quantity of monitoring occasions corresponding to the quantity of synchronization rasters and transmit random access signaling to the base station based on which synchronization raster of which beam provides a greatest signal strength at the UE.
