Abstract  Abstract

A packet communication method according to the present invention includes the steps of: starting at a predetermined sublayer of a receiving-side apparatus a reordering timer when receiving a second packet before receiving a first packet in a case where a sequence number of the first packet is smaller than a sequence number of the second packet; and transmitting at the predetermined sublayer of the receiving-side apparatus a retransmission request for the first packet when not receiving the first packet until the reordering timer expires.
