Abstract

A method and an apparatus for processing scheduling information in a terminal into which a plurality of forward carriers and reverse carriers are aggregated are provided. The method includes receiving a control message from a base station, the control message including information on a reverse carrier added by the carrier aggregation, and determining a new buffer state table to be used for reporting the state of buffers to the base station, based on the information included in the control message.

Claims

1. A method of transmitting a Buffer State Report (BSR) by a User Equipment (UE), the method comprising:

determining whether a BSR is triggered;

selecting a Buffer Status (BS) table from among at least two BS tables;

determining a BS index from the selected BS table; and

transmitting the BSR including the determined BS index,

wherein a specific field of a MAC subheader of the BSR is set to a predetermined value indicating the selected BS table.

2. The method of claim 1, wherein the determining of the BS index from the selected BS table further comprises:

determining the BS index from the selected BS table based on amount of data available for transmission of each Logical Channel Group (LCG).

3. The method of claim 2,

wherein the MAC subheader included in the MAC PDU (Packet Data unit), and

wherein the BSR further includes a LCG identifier.

4. The method of claim 3,

wherein the MAC PDU further includes a Logical Channel identifier (LCID) indicating a type of the BSR, and

wherein the type of the BSR comprises at least one of a long BSR, a short BSR or a truncated BSR.

5. The method of claim 1, further comprising:

receiving a control message for the BSR, from a base station, wherein the control message is a Radio Resource Control (RRC) message.

6. A method of receiving a Buffer State Report (BSR) by a base station, the method comprising:

transmitting, to a user equipment (UE), a control message for a BSR (Buffer Status Report);

receiving the BSR including a BS index and a predetermined value indicating a Buffer Status (BS) table corresponding the BS index; and

identifying the BS table based on the predetermined value,

wherein the predetermined value indicating the Buffer Status (BS) table is included in a specific field of a MAC subheader of the BSR.

7. The method of claim 6, the BS index is determined based on amount of data available for transmission of each Logical Channel Group (LCG).

8. The method of claim 7,

wherein the MAC subheader included in the MAC PDU (Packet Data unit), and

wherein the BSR further includes a LCG identifier.

9. The method of claim 8,

wherein the MAC PDU further includes a Logical Channel identifier (LCID) indicating a type of the BSR, and

wherein the type of the BSR comprises at least one of a long BSR, a short BSR or a truncated BSR.

10. The method of claim 6, wherein the control message is a Radio Resource Control (RRC) message.

11. A user equipment (UE) transmitting a Buffer State Report (BSR), the UE comprising:

a transceiver; and

a processor coupled with the transceiver and configured to determine whether a BSR is triggered,

select a Buffer Status (BS) table from among at least two BS tables,

determine a BS index from the selected BS table, and

transmit the BSR including the determined BS index,

wherein a specific field of a MAC subheader of the BSR is set to a predetermined value indicating the selected BS table.

12. The UE of claim 11, wherein the processor is further configured to the BS index from the selected BS table based on amount of data available for transmission of each Logical Channel Group (LCG).

13. The UE of claim 12,

wherein the MAC subheader included in the MAC PDU (Packet Data unit), and

wherein the BSR further includes a LCG identifier.

14. The UE of claim 13,

wherein the MAC PDU further includes a Logical Channel identifier (LCID) indicating a type of the BSR, and

wherein the type of the BSR comprises at least one of a long BSR, a short BSR or a truncated BSR.

15. The UE of claim 11, wherein the processor is further configured to receive a control message for the BSR, from a base station, wherein the control message is a Radio Resource Control (RRC) message.

16. A base station receiving a Buffer State Report (BSR), the base station comprising:

a transceiver; and

a processor coupled with the transceiver and configured to;

transmit, to a user equipment (UE), a control message for a BSR (Buffer Status Report),

receive the BSR including a BS index and a predetermined value indicating a Buffer Status (BS) table corresponding the BS index, and

identify the BS table based on the predetermined value,

wherein the predetermined value indicating the Buffer Status (BS) table is included in a specific field of a MAC subheader of the BSR.

17. The base station of claim 16, the BS index is determined based on amount of data available for transmission of each Logical Channel Group (LCG).

18. The base station of claim 17,

wherein the MAC subheader included in the MAC PDU (Packet Data unit), and

wherein the BSR further includes a LCG identifier.

19. The base station of claim 18,

wherein the MAC PDU further includes a Logical Channel identifier (LCID) indicating a type of the BSR, and

wherein the type of the BSR comprises at least one of a long BSR, a short BSR or a truncated BSR.

20. The base station of claim 16, wherein the control message is a Radio Resource Control (RRC) message.
