1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, first system information (SI) which is broadcasted periodically, the first SI including first information indicating whether a second SI other than the first SI is being broadcasted or not and second information on a physical random access channel (PRACH) resource; transmitting, to the base station, a PRACH preamble on the PRACH resource to request the second SI, based on the first information included in the first SI indicating that the second SI is not being broadcasted; and receiving, from the base station, the requested second SI based on the PRACH preamble.
2. The method of claim 1, wherein the first SI further includes information on the PRACH preamble corresponding to the second SI.
3. The method of claim 1, 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,
wherein a time window is monitored for the requested second SI, and wherein a length of the time window is identified based on the first SI.
5. The method of claim 1, wherein the first SI further includes an SI area identifier (ID) for an area including one or more cells with which the second SI is applied.
6. A method performed by a base station in a wireless communication system, the method comprising:
transmitting, to a terminal, first system information (SI) which is broadcasted periodically, the first SI including first information indicating whether a second SI other than the first SI is being broadcasted or not and second information on a physical random access channel (PRACH) resource; receiving, from the terminal, a PRACH preamble on the PRACH resource for the second SI, based on the first information included in the first SI indicating that the second SI is not being broadcasted; and transmitting, to the terminal, the requested second SI based on the PRACH preamble.
7. The method of claim 6, wherein the first SI further includes information on the PRACH preamble corresponding to the second SI.
8. The method of claim 6, further comprising:
transmitting, to the terminal, a random access response (RAR) as a response to the PRACH preamble, wherein the second SI is transmitted based on the RAR.
9. The method of claim 6,
wherein a time window is monitored for the requested second SI, and wherein a length of the time window is identified based on the first SI.
10. The method of claim 6, wherein the first SI further includes an SI area identifier (ID) for an area including one or more cells with which the second SI is applied.
11. A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit or receive a signal; and a controller coupled with the transceiver and configured to:
receive, from a base station, first system information (SI) which is broadcasted periodically, the first SI including first information indicating whether a second SI other than the first SI is being broadcasted or not and second information on a physical random access channel (PRACH) resource,
transmit, to the base station, a PRACH preamble on the PRACH resource to request the second SI, based on the first information included in the first SI indicating that the second SI is not being broadcasted, and
receive, from the base station, the requested second SI based on the PRACH preamble.
12. The terminal of claim 11, wherein the first SI further includes information on the PRACH preamble corresponding to the second SI.
13. The terminal of claim 11,
wherein the controller is further configured to receive, from the base station, a random access response (RAR) as a response to the PRACH preamble, and wherein the second SI is received based on the RAR.
14. The terminal of claim 11,
wherein a time window is monitored for the requested second SI, and wherein a length of the time window is identified based on the first SI.
15. The terminal of claim 11, wherein the first SI further includes an SI area identifier (ID) for an area including one or more cells with which the second SI is applied.
16. A base station in a wireless communication system, the base station comprising:
a transceiver configured to transmit or receive a signal; and a controller coupled with the transceiver and configured to:
transmit, to a terminal, first system information (SI) which is broadcasted periodically, the first SI including first information indicating whether a second SI other than the first SI is being broadcasted or not and second information on a physical random access channel (PRACH) resource,
receive, from the terminal, a PRACH preamble on the PRACH resource for the second SI, based on the information included in the first SI indicating that the second SI is not being broadcasted, and
transmit, to the terminal, the requested second SI based on the PRACH preamble.
17. The base station of claim 16, wherein the first SI further includes information on the PRACH preamble corresponding to the second SI.
18. The base station of claim 16,
wherein the controller is further configured to transmit, a random access response (RAR) as a response to the PRACH preamble, and wherein the second SI is transmitted based on the RAR.
19. The base station of claim 16,
wherein a time window is monitored for the requested second SI, and wherein a length of the time window is identified based on the first SI.
20. The base station of claim 16, wherein the first SI further includes an SI area identifier (ID) for an area including one or more cells with which the second SI is applied.
