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.
