Method of transmitting data in a wireless communication system
First Claim
1. A method of generating a data block to be transmitted to a receiving side at a protocol layer performing a header compression function in a wireless communication system, the method comprising:
- generating at least one of a compressed packet by performing the header compression function for an upper layer data block received from an upper layer and a control packet having no relation with the upper layer data block; and
if the compressed packet is generated, generating a first lower layer data block which includes the compressed packet, and generating a second lower layer data block which includes the control packet, wherein each of the first lower layer data block and the second lower layer data block includes an indicator indicating whether the corresponding lower layer data block includes the compressed packet or the control packet, and wherein the second lower data block further includes type indication information indicating whether the control packet includes header compression feedback information, and wherein the first lower layer data block is generated by ciphering the compressed packet and adding the indicator to the ciphered compressed packet whereas the second lower data block is generated by adding the indicator and the type indication information to the control packet without ciphering the control packet.

Abstract
A method of generating a data block to be transmitted from a protocol layer to a receiving side in a wireless communication system, the protocol layer having a header compression function, comprises generating at least one of a control packet which includes control information and a compressed packet generated by header compression for an upper layer data block, and generating a first lower layer data block which includes type indication information and the control packet, if the control packet is generated, the type indication information indicating a type of control information included in the generated control packet.

6. A method of receiving a data block transmitted by a transmitting side at a protocol layer performing a header compression function, the method comprising:
-
determining, based on an indicator included in the data block, whether the data block includes a compressed packet generated by performing the header compression function for an upper layer data block at a protocol layer of the transmitting side or a control packet having no relation with the upper layer data block; if the indicator indicates that the data block includes the control packet, determining, based on type indication information included in the data block, whether the control packet includes header compression feedback information, wherein; if the data block includes the compressed packet, the method further comprises; de-ciphering the compressed packet; performing header de-compression on the de-ciphered compressed packet; and transferring the de-compressed packet to an upper layer of a receiving side, and if the data block includes the control packet, the method further comprises; transferring the control packet to the upper layer of the receiving side without de-ciphering or without de-compressing the control packet. - View Dependent Claims (7, 8, 9, 10, 11, 13)
