Abstract

Accordingly the embodiments herein provide a method for provisioning Minimum System Information (MSI) for User Equipment (UE) in a wireless communication system. The method includes decoding Primary Broadcast Channel (PBCH) to acquire a first Master Information Block (MIB) periodically transmitted by base station. Further, the method includes determining to perform one of bar a cell from which the first MIB is acquired for a pre-determined period of time and acquire second MIB transmitted on Secondary Broadcast Channel (SBCH) by base station based on cell barring indication received in the first MIB. Furthermore, the method includes transmitting a request message to the base station to obtain at least one SI block of the OSI. In some embodiments, the method includes receiving a list of system configuration indexes (SCIs) and corresponding configuration of SI blocks, from the base station based on SI storage capability of the UE indicated to the base station.

First claim

What is claimed is:

1. A method of receiving system information by a terminal in a wireless communication system, the method comprising:
receiving, from a base station in the wireless communication system, a master information block (MIB) that includes first information indicating whether a cell is barred;
receiving, from the base station, a system information block 1 (SIB1) based on the MIB, in case that the first information indicates that the cell is not barred; and
transmitting, to the base station, a preamble of a random access procedure that is based on second information on a resource to request at least one system information block (SIB) of other system information (SI), in case that the SIB1 includes the second information on the resource for requesting the other SI.

2. The method of claim 1 , further comprising:
receiving, from the base station, an acknowledgement of a request for the at least one SIB included in the preamble; and
receiving, from the base station, the at least one SIB in an SI window configured by the SIB1.

3. The method of claim 2 , wherein the acknowledgement is included in a MSG2 of the random access procedure.

4. The method of claim 1 ,
wherein the SIB1 further includes third information on the preamble for requesting the other SI, and
wherein the preamble is generated based on the third information.

5. The method of claim 4 , wherein the preamble is transmitted on a time-frequency resource identified by the second information.

6. The method of claim 1 , wherein the SIB1 further includes third information on a valuetag corresponding to an SIB of the other SI.

7. The method of claim 1 , wherein the other SI comprises at least one SIB set to not broadcasting.

8. A method of transmitting system information by a base station in a wireless communication system, the method comprising:
transmitting, to a terminal in the wireless communication system, a master information block (MIB) that includes first information indicating whether a cell is barred;
transmitting, to the terminal, a system information block 1 (SIB1) based on the MIB, wherein the SIB1 is received by the terminal in case that the first information indicates that the cell is not barred; and
receiving, from the terminal, a preamble of a random access procedure that is based on second information on a resource, the preamble transmitted by the terminal being to request at least one system information block (SIB) of other system information (SI) in case that the SIB1 includes second information on the resource for requesting the other SI.

9. The method of claim 8 , further comprising:
transmitting, to the terminal, an acknowledgement of a request for the at least one SIB included in the preamble; and
transmitting, to the terminal, the at least one SIB in an SI window configured by the SIB1.

10. The method of claim 9 , wherein the acknowledgement is included in a MSG2 of the random access procedure.

11. The method of claim 8 ,
wherein the SIB1 further includes third information on the random access preamble for requesting the other SI, and
wherein the preamble is generated based on the third information.

12. The method of claim 11 , wherein the preamble is received on a time-frequency resource identified by the second information.

13. The method of claim 8 , wherein the SIB1 further includes third information on a valuetag corresponding to an SIB of the other SI.

14. The method of claim 8 , wherein the other SI comprises at least one SIB set to not broadcasting.

15. A terminal of receiving system information in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to:
receive, from a base station in the wireless communication system, a master information block (MIB) that includes first information indicating whether a cell is barred,
receive, from the base station, a system information block 1 (SIB1) based on the MIB, in case that the first information indicates that the cell is not barred, and
transmit, to the base station, a preamble of a random access procedure that is based on second information on a resource to request at least one system information block (SIB) of other system information (SI), in case that the SIB1 includes the second information on the resource for requesting the other SI.

16. The terminal of claim 15 , wherein the controller is further configured to:
receive, from the base station, an acknowledgement of a request for the at least one SIB included in the preamble, and
receive, from the base station, the at least one SIB in an SI window configured by the SIB1.

17. The terminal of claim 16 , wherein the acknowledgement is included in a MSG2 of the random access procedure.

18. The terminal of claim 15 ,
wherein the SIB1 further includes third information on the random access preamble for requesting the other SI, and
wherein the preamble is generated based on the third information.

19. The terminal of claim 18 , wherein the preamble is transmitted on a time-frequency resource identified by the second information.

20. The terminal of claim 15 , wherein the SIB1 further includes third information on a valuetag corresponding to an SIB of the other SI.

21. The terminal of claim 15 , wherein the other SI comprises at least one SIB set to not broadcasting.

22. A base station of transmitting system information in a wireless communication system, the base station comprising:
a transceiver configured to transmit and receive a signal; and
a controller configured to:
transmit, to a terminal in the wireless communication system, a master information block (MIB) that includes first information indicating whether a cell is barred,
transmit, to the terminal, a system information block 1 (SIB1) based on the MIB, wherein the SIB1 is received by the terminal in case that the first information indicates that the cell is not barred, and
receive, from the terminal, a preamble of a random access procedure that is based on second information on a resource, the preamble transmitted by the terminal being to request at least one system information block (SIB) of other system information (SI) in case that the SIB1 includes second information on the resource for requesting the other SI.

23. The base station of claim 22 , wherein the controller is further configured to:
transmit, to the terminal, an acknowledgement of a request for the at least one SIB included in the preamble, and
transmit, to the terminal, the at least one SIB in a system information (SI) window configured by the SIB1.
