Various aspects generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a physical random access channel (PRACH) to request an on-demand system information block (SIB) including remaining minimum system information (RMSI). The UE may receive, from the network node in response to the PRACH, a random access response (RAR) protocol data unit (PDU) that includes information for the on-demand SIB. The UE may receive, from the network node, the on-demand SIB based at least in part on the information included in the RAR PDU. In some aspects, the UE may receive, from the network node in response to the PRACH, only a physical downlink control channel (PDCCH) for an RAR during an RAR window. The UE may receive, from the network node, the on-demand SIB based at least in part on the PDCCH for the RAR. Numerous other aspects are described.
