In method for transmitting a retransmission request, at the timing for generating STATUS-PDU, an RLC sub-layer in a receiving side device determines whether, in a MAC sub-layer, retransmission control processing is performed on RLC-PDU-data (or RLC-data-Sub-PDU) that has not been received yet. Based on this determination result, the RLC sub-layer generates and transmits the STATUS-PDU (NACK) including only the RLC-data-PDU which has not yet been received and on which the retransmission control processing is not performed in the MAC sub-layer. |
