摘要： A communication system comprises a radio transmission apparatus for retransmitting data and a radio reception apparatus for receiving the retransmitted data. The radio transmission apparatus is configured to add a sequential number, first information and second information to each of a plurality of divided data which is generated by dividing the data to be retransmitted, and to transmit the plurality of divided data including the sequential number, the first information and the second information to the radio reception apparatus. The sequential number identifies the data to be retransmitted, 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.

摘要： A radio receiving apparatus for receiving variable-length RLC PDU data in an RLC layer is provided that includes a 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. According to the present invention, when the RLCU PDU data in the RLC layer is modified to have a variable length, a buffer memory for storing the RLC PDU data received in the radio receiving apparatus can be used efficiently without capacity being wasted.

摘要： In a LTE-based wireless communication system, a wireless receiver includes a ciphering processing section (12) that applies a deciphering process to ciphered packet data based on a deciphering key held by a key holding part (122) and a count value sequentially updated by a counting part (123). The ciphering processing section (12) further comprises a success/failure determining part (124) that determines success/failure of the deciphering process and a query part (125) that queries a transmitting wireless communication device about a resynchronization count value when a failure of the deciphering process is determined, and that receives the resynchronization count value from the transmitting wireless communication device. The counting part (123) sequentially updates the count value with the received resynchronization count value as an initial value. The ciphering processing section (12) executes a deciphering process of packet data using the sequentially updated count value.
