Claim 13:
14. A method for a central unit (CU) of an NG-RAN in a wireless communication system, the method comprising:
transmitting, by the CU to a distributed unit (DU) of the NG-RAN, an F1 setup response message including multiple system information blocks (SIBs) provided by the CU,
wherein the DU receives, from a wireless device, a system information request for a specific SIB;
receiving, by the CU from the DU, the system information request via a first message including a container which piggybacks the system information request; and
transmitting, by the CU to the DU, a second message including an enumerated type of the specific SIB, wherein the enumerated type identifies the specific SIB from among the multiple SIBs provided by the CU,
wherein upon receiving the second message from the CU, the DU broadcasts a system information (SI) message related to the specific SIB,
wherein the CU has a radio resource control (RRC) layer, a service data adaptation protocol (SDAP) layer, and a packet data convergence protocol (PDCP) layer, and
wherein the DU has a radio link control (RLC) layer, a media access control (MAC) layer, and a physical (PHY) layer.
