Abstract

A device and method for receiving, by a mobile terminal, system information from a base station. The method includes: receiving a block of first system information from the base station via a broadcast channel configured to broadcast only system information; and receiving a plurality of blocks of second system information from the base station via a downlink shared channel configured to carry system information and other data, one of the plurality of blocks of second system information including scheduling information.

Claims (38)

1. A method for receiving, by a user equipment (UE) from a base station, system information via a broadcast control channel (BCCH), the method comprising:

receiving a block of first system information from the base station via a broadcast channel (BCH);

after the block of the first system information is received, receiving a first block of the second system information from the base station via a downlink shared channel (DL SCH), the first block of the second system information including schedule information; and

after the first block of the second system information is received, receiving at least one second block of the second system information from the base station via the DL SCH in accordance with the schedule information included in the first block of the second system information,

wherein the first block of the second system information follows the block of the first system information with a fixed time offset,

wherein the first block of the second system information and the at least one second block of the second system information are received via the DL SCH in accordance with a specific control channel,

wherein the specific control channel indicates information about frequency and time resource in which the first block of the second system information and the at least one second block of the second system information are received, and

wherein the at least one second block of the second system information comprises plural second blocks of the second system information, each second block of the second system information being mutually exclusive.

2. The method of claim 1 , wherein the block of the first system information and the first block of the second system information are scheduled for being transmitted periodically.

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

4. The method of claim 1 , wherein the at least one second block of the second system information further comprises at least one of:

paging information;

a cell select related information;

a positioning related information; or

a Multimedia Broadcast Multicast Service (MBMS) related information.

5. The method of claim 1 , wherein the DL_SCH supports HARQ (hybrid automatic repeat request) scheme.

6. The method of claim 1 , wherein the first block of the second system information further includes value tag information and cell access related information, and

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

7. The method of claim 1 , wherein the specific control channel is a L1/L2 control channel.

8. A method for transmitting, by a base station to at least one user equipment (UE), system information via a broadcast control channel (BCCH), the method comprising:

transmitting a block of first system information to the at least one UE via a broadcast channel (BCH);

after the block of the first system information is transmitted, transmitting a first block of second system information to the at least one UE via a downlink shared channel (DL SCH), the first block of the second system information including schedule information; and

after the first block of the second system information is transmitted, transmitting at least one second block of the second system information to the at least one UE via the DL SCH in accordance with the schedule information included in the first block of the second system information,

wherein the first block of the second system information follows the block of the first system information with a fixed time offset,

wherein the first block of the second system information and the at least one second block of the second system information are transmitted via the DL SCH in accordance with a specific control channel,

wherein the specific control channel indicates information about frequency and time resource in which the first block of the second system information and the at least one second block of the second system information are received, and

wherein the at least one second block of the second system information comprises plural second blocks of the second system information, each second block of the second system information being mutually exclusive.

9. The method of claim 8 , wherein the block of the first system information and the first block of the second system information are scheduled for being transmitted periodically.

10. The method of claim 8 , wherein the block of the first system information includes at least one of bandwidth information or parameter information about a physical layer.

11. The method of claim 8 , wherein the at least one second block of the second system information further comprises at least one of:

paging information;

a cell select related information;

a positioning related information; or

a Multimedia Broadcast Multicast Service (MBMS) related information.

12. The method of claim 8 , wherein the DL_SCH supports HARQ (hybrid automatic repeat request) scheme.

13. The method of claim 8 , wherein the first block of the second system information further includes value tag information and cell access related information, and

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

14. The method of claim 8 , wherein the specific control channel is a L1/L2 control channel.
