Abstract

Disclosed is a method for generating a data block to be transmitted from a specific layer in a transmitting side to a receiving side in a wireless communication system. The method includes receiving an upper layer datei block from an upper layer and generating a lower layer data block including at least part of the upper layer data block and state indication information indicating a state of the upper layer data block, the state indication information being selected variably according to a logical channel through which the upper layer data block is received. This method optimizes overhead of a header of each upper layer data block according to contents of the upper layer data block and event situations associated with the upper layer data block, thereby increasing system efficiency.

Claims

1. A method for generating a data block to be transmitted from a specific layer in a transmitting side to a receiving side in a wireless communication system, the method comprising:

receiving an upper layer data block from an upper layer; and

generating a lower layer data block including at least part of the upper layer data block and state indication information indicating a state of the upper layer data block, the state indication information being selected variably according to a logical channel through which the upper layer data block is received.

2. The method according to claim 1, wherein the upper layer data block includes an IP packet.

3. The method according to claim 1, wherein the upper layer data block includes a voice packet.

4. The method according to claim 1, wherein the upper layer data block includes predetermined control information.

5. The method according to claim 2, wherein the state indication information indicates whether a header of the IP packet is a full header or a compressed header.

6. The method according to claim 2, wherein the state indication information indicates whether the voice packet has been generated in a talk spurt period or a silent period.

7. The method according to claim 2, wherein the state indication information indicates whether the control information is urgent information or non-urgent information.

8. The method according to claim 1, wherein the state indication information is included in a sub-header corresponding to the upper layer data block.

9. The method according to claim 8, wherein the sub-header further includes an identifier of the logical channel.

10. A data block structure transmitted from a specific layer in a transmitting side to a receiving side in a wireless communication system, the data block structure comprising:

a first field including an identifier of a logical channel through which an upper layer data block is received;

a second field including state indication information indicating a state of the upper layer data block received from an upper layer, the state indication information being selected variably according to the logical channel through which the upper layer data block is received; and

at least part of the upper layer data block.

11. The data block structure according to claim 10, wherein the data block structure further comprises a third field including information indicating a size of the upper layer data block.

12. The data block structure according to claim 10, wherein the state indication information is included in a sub-header corresponding to the upper layer data block.

13. The data block structure according to claim 12, wherein the sub-header further includes at least one of the size indication information and the identifier of the logical channel.
