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.
Claims17
A transmitting apparatus for generating a data block to be transmitted to a receiving apparatus in a wireless communication system, the transmitting apparatus comprising:
- a processor configured to generate a first lower layer data block which includes a data packet received from an upper layer and generate a second lower layer data block which includes a 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 data packet or the control packet,
- wherein the second lower layer data block further includes type indication information indicating whether the control packet includes header compression feedback information,
- wherein the processor is configured to add the indicator to the data packet to generate the first lower layer data block, and the processor is configured to add the indicator and the type indication information to the control packet to generate the second lower layer data block, and
- wherein the processor is configured to generate the first lower layer data block to include a sequence number and generate the second lower layer data block not to include a sequence number.
A receiving apparatus for receiving a data block transmitted by a transmitting apparatus in a wireless communication system, the receiving apparatus comprising:
- a processor configured to determine, based on an indicator included in the data block, whether the data block includes a data packet of an upper layer of the transmitting apparatus or a control packet;
- and if the indicator indicates that the data block includes the control packet, configured to determine, 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 data packet, the processor is configured to remove a sequence number from the data block and transfer the data packet to an upper layer of the receiving apparatus, and
- wherein the data block does not include a sequence number if the data block includes the control packet.
