First Claim
Patent Images
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.

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.

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).
