Abstract

A method of configuring a lower layer data block in a protocol layer of a transmitting side of a wireless communication system comprises receiving upper layer data from an upper layer, and configuring a second lower layer data block to include a first upper layer data block comprising at least part of the upper layer data, and a size change indictor indicating whether a size of the first upper layer data block is identical with a size of a second upper layer data block included in a first lower layer data block.

Claims

1. A method of configuring a lower layer data block in a protocol layer of a transmitting side in a wireless communication system, the method comprising:

receiving upper layer data from an upper layer; and

configuring a second lower layer data block to include a first upper layer data block comprising at least part of the upper layer data, and a size change indictor indicating whether a size of the first upper layer data block is identical with a size of a second upper layer data block included in a first lower layer data block,

wherein, if the size change indicator indicates that the size of the first upper layer data block is different from the size of the second upper layer data block, the second lower layer data block further includes a length field which indicates the size of the first upper layer data block.

2. The method of claim 1, wherein, if the size change indicator indicates that the size of the first upper layer data block is identical with the size of the second upper layer data block, the second lower layer data block does not include a length field which indicates the size of the first upper layer data block.

3. The method of claim 1, wherein the size change indicator is included in a header of the second lower layer data block.

4. The method of claim 1, wherein the size change indicator and the length field are included in a header of the second lower layer data block.

5. The method of claim 1, wherein the first upper layer data block and the second upper layer data block include upper layer data transferred from the upper layer through a single logical channel.

6. A method of generating a lower layer data block in a protocol layer of a transmitting side in a wireless communication system, the method comprising:

generating a first lower layer data block which includes a first upper layer data block, and a first length field indicating a size of the first upper layer data block; and

generating a second lower layer data block which includes a second upper layer data block, and a size change indictor indicating whether a size of the second upper layer data block is identical with a size of the first upper layer data block,

wherein, if the size change indicator indicates that the size of the first upper layer data block is different from the size of the second upper layer data block, the second lower layer data block further includes a length field which indicates the size of the second upper layer data block.

7. The method of claim 6, wherein, if the size change indicator indicates that the size of the first upper layer data block is identical with the size of the second upper layer data block, the second lower layer data block does not include a length field which indicates the size of the second upper layer data block.

8. The method of claim 6, wherein the size change indicator is included in a header of the second lower layer data block.

9. The method of claim 6, wherein the size change indicator and the length field are included in the header of the second lower layer data block.

10. The method of claim 6, wherein the first upper layer data block and the second upper layer data block include upper layer data transferred from the upper layer through an identical logical channel.

11. A method of transmitting data from a transmitting side of a wireless communication system to a receiving side, the method comprising:

transmitting a first lower layer data block to the receiving side, the first lower layer data block including a first upper layer data block and a first length field indicating a size of the first upper layer data block; and

transmitting a second lower layer data block to the receiving side, the second lower layer data block including a second upper layer data block and a size change indictor indicating whether a size of the second upper layer data block is identical with a size of the first upper layer data block,

wherein, if the size change indicator indicates that the size of the first upper layer data block is different from the size of the second upper layer data block, the second lower layer data block further includes a length field which indicates the size of the second upper layer data block.
