Abstract
In a retransmitting method, at least one ARQ block included in a first PDU is fragmented into a plurality of ARQ sub-blocks, and at least one second PDU is generated from the plurality of ARQ sub-blocks. The second PDU includes a payload including an extended header and at least some of a plurality of ARQ sub-blocks. The extended header includes a field representing a sequence number of the first ARQ sub-block belonging to the payload.
Claims23
A method of retransmitting a protocol data unit (PDU) in a transmitting apparatus of a wireless communication system, the method comprising:
- fragmenting at least one automatic repeat request (ARQ) block that is included in a first PDU into a plurality of ARQ sub-blocks;
- allocating at least one ARQ sub-block of the plurality of ARQ sub-blocks to a payload of a second PDU;
- allocating a first field representing a sequence number of the first ARQ sub-block belonging to the payload of the second PDU to a header of the second PDU;
- and
- transmitting the second PDU.
A method of retransmitting a PDU in a transmission apparatus of a wireless communication system, the method comprising:
- fragmenting at least one ARQ block that is included in a first PDU into a plurality of ARQ sub-blocks;
- generating a second PDU from at least one ARQ sub-block of the plurality of ARQ sub-blocks;
- and
- transmitting the second PDU,
- wherein the second PDU comprises:
- a header;
- and
- a payload comprising the at least one ARQ sub-block,
- wherein the header comprises a first field representing whether the payload comprises a last ARQ sub-block.
A transmitting apparatus of a wireless communication system, comprising:
- a refragmentation unit that fragments at least one ARQ block included in a first PDU into a plurality of ARQ sub-blocks and that allocates at least one ARQ sub-block of the plurality of ARQ sub-blocks to a payload of a second PDU;
- a PDU generator that allocates a header including a field representing whether a payload thereof includes a last ARQ sub-block to the second PDU;
- and
- a transmitting/receiving unit that transmits the second PDU.
