Abstract
A radio receiving apparatus for receiving the variable-length RLC PDU data in an RLC layer includes the buffer memory sectioned into a plurality of areas having a predetermined maximum data length of the RLC PDU data. By referring to a sequence number SN included in each received RLC PDU data, the radio receiving apparatus stores the RLC PDU data having an identical sequence number SN into an identical area, and assembles an RLC SDU data on a basis of the RLC PDU data stored in each area.
Claims4
A method for retransmitting data from a transmission apparatus to a reception apparatus, comprising:
- the transmission apparatus adding a sequential number, first information and second information to each of the plurality of divided data which is generated by dividing the data to be retransmitted;
- and
- the transmission apparatus transmitting the plurality of divided data including the sequential number, the first information and the second information to the reception apparatus,
- wherein the first information indicates the position of each of the plurality of divided data in the data to be retransmitted, and the second information indicates whether each of the plurality of the divided data is last data in the plurality of the divided data.
