Abstract
PROBLEM TO BE SOLVED: To allow an RLC sub-layer to appropriately detect an occurrence of a packet loss in a case where a MAC sub-layer does not perform order correction processing for received RLC-PDUs.
SOLUTION: A packet communication method includes a step of starting up an order correction timer when the sequence number of a first packet is smaller than the sequence number of a second packet and if a predetermined sub-layer of a receiving-side device has received the second packet before receiving the first packet and a step of transmitting a retransmission request of the first packet if the predetermined sub-layer of the receiving-side device has not received the first packet until the order correction timer terminates.
