Abstract
The present disclosure relates to a communication method and system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for internet of things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for receiving system information (SI) by a user equipment (UE) in a wireless communication system is provided. The method includes receiving, from a base station (BS), first type SI associated with SI which is essential for communication with the BS, transmitting, to the BS, a physical random access channel (PRACH) preamble based on the first type SI, receiving, from the BS, a random access response (RAR) message, and receiving, from the BS, second type SI associated with at least one SI which the UE needs.

wherein the SI request is transmitted based on the PRACH preamble and the PRACH resource.
3. The method of claim 2, further comprising:
receiving, from the base station, a random access response (RAR) as a response to the PRACH preamble,
wherein the second SI is received based on the RAR.
4. The method of claim 1, further comprising:
transmitting, to the base station, a physical random access channel (PRACH) preamble; and
receiving, from the base station, a random access response (RAR) as a response to the PRACH preamble, the RAR including an uplink (UL) grant for a message 3 (MSG3),

wherein the SI request is received based on the PRACH preamble and the PRACH resource.
15. The base station of claim 14, wherein the controller is configured to transmit, to the terminal, a random access response (RAR) as a response to the PRACH preamble, and
wherein the second SI is transmitted based on the RAR.
16. The base station of claim 13,
wherein the controller is further configured to:
receive, from the terminal, a physical random access channel (PRACH) preamble, and
transmit, to the terminal, a random access response (RAR) as a response to the PRACH preamble, the RAR including an uplink (UL) grant for a message 3 (MSG3), and
wherein the MSG3 received on the UL grant includes the SI request.
