Abstract: Systems and methods for on-demand system information block (SIB) 1 (SIB1) acquisition are disclosed herein. In some embodiments, a user equipment (UE) communicates with an anchor cell to either receive essential SIB (ESIB) information of a network energy saving (NES) cell that is not regularly transmitting its SIB1 or receive a SIB1 of the NES cell. In alternative embodiments, no anchor cell communication occurs, and a concise random access channel (RACH) configuration is retrieved from an SSB of the NES cell. Then, the UE performs an on-demand system information (SI) request RACH procedure that includes a request for the NES cell to transmit its SIB1 (e.g., for purposes of SIB1 acquisition or update). The RACH procedure may be a "Msg1" on-demand SI request RACH procedure or a "Msg3" on- demand SI request RACH procedure across applicable embodiments. Corresponding anchor cell and NES cell behaviors for applicable embodiments are also discussed.
