Abstract

A method for receiving system information, the method includes receiving, by a mobile terminal, a first block of second system information from a base station, wherein the first block of second system information includes scheduling information related to a plurality of second blocks of second system information; determining, by the mobile terminal, on which resource the plurality of second blocks of second system information is received using the scheduling information; and receiving, by the mobile terminal, the plurality of second blocks of second system information from the base station on the determined resource.

Claims

1. A method for receiving system information, the method comprising:

receiving, by a mobile terminal, a block of first system information on a broadcast channel (BCH) from a base station;

receiving, by the mobile terminal, a first block of second system information from the base station on a downlink shared channel (DL-SCH), wherein the first block of second system information includes cell access related information and scheduling information related to a plurality of second blocks of second system information;

determining, by the mobile terminal, on which resource of the DL-SCH the plurality of second blocks of second system information are received using the scheduling information and information on a L1/L2 control channel; and

receiving, by the mobile terminal, the plurality of second blocks of second system information from the base station on the determined resource of the DL-SCH.

2. The method of claim 1, wherein the scheduling information includes periodicity information of each of the second blocks.

3. The method of claim 1, wherein one of the plurality of second blocks of second system information further includes value tag information.

4. The method of claim 1, wherein the first block of second system information is received after a predetermined time difference after the block of first system information is received.

5. The method of claim 1, wherein the block of first system information includes at least one of bandwidth information or parameter information about a physical layer.

6. The method of claim 1, wherein the plurality of second blocks of second system information received from the base station are configured to carry user traffic.

7. The method of claim 1, wherein the plurality of second blocks of second system information further include at least one of:

paging information,

a cell select related information,

a positioning related information, or

a Multimedia Broadcast Multicast Service (MBMS) related information.

8. The method of claim 1, wherein the first block of second system information further includes value tag information, and

wherein the cell access related information includes at least one of Public Land Mobile Network (PLMN) identity information, tracking area information, or cell barred information.

9. A mobile terminal for receiving system information, the mobile terminal comprising:

a transmitter and a receiver;

at least one processor; and

at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising;

receiving a block of first system information on a broadcast channel (BCH) and a first block of second system information on a downlink shared channel (DL-SDH) from a base station, wherein the first block of second system information includes cell access related information and scheduling information related to a plurality of second blocks of second system information;

determining on which resource of the DL-SCH the plurality of second blocks of second system information are received using the scheduling information and information on a L1/L2 control channel; and

receiving the plurality of second blocks of second system information from the base station on the determined resource of the DL-SCH.

10. The mobile terminal of claim 9, wherein the plurality of second blocks of second system information further include at least one of:

paging information,

a cell select related information,

a positioning related information, or

a Multimedia Broadcast Multicast Service (MBMS) related information.

11. The mobile terminal of claim 9, wherein the first block of second system information further includes value tag information, and

wherein the cell access related information includes at least one of Public Land Mobile Network (PLMN) identity information, tracking area information, or cell barred information.

12. The mobile terminal of claim 9, wherein the scheduling information includes periodicity information of each of the second blocks.

13. The mobile terminal of claim 9, wherein one of the plurality of second blocks of second system information further includes value tag information.

14. The mobile terminal of claim 9, wherein the first block of second system information is received after a predetermined time difference after the block of first system information is received.

15. The mobile terminal of claim 9, wherein the block of first system information includes at least one of bandwidth information or parameter information about a physical layer.

16. The mobile terminal of claim 9, wherein the plurality of second blocks of second system information received from the base station are configured to carry user traffic.
