This indication corresponding to a reflected beam may be sent on the reverse path via a reflection at the IRS. According to certain example embodiments, during transmission of the indication corresponding to a reflected beam, the IRS may be configured to receive signals from that same direction and reflect them toward the gNB. In other example embodiments, when transmitting other signals/channels to the UE, the gNB may use either a direct beam (IRS off) or a reflected beam (IRS configured to reflect along a particular departure angle from the IRS)]; receiving a random access message from a user equipment (UE) during a random access occasion that corresponds with the synchronization signal block index [par 0088, Fig 12, label 245, the RACH configuration may define the association between RACH occasion and SSBs such that the there is a unique RACH occasion corresponding to each SSB.
