Packet communication device and packet communication method

摘要

A packet communication apparatus and a packet communication method capable of suppressing decrease in overall system throughput and preventing communication from being reset or disconnected. An ACK generation section ( 130 ) generates an ACK/NACK to indicate whether or not data transmitted on the radio channel has been demodulated correctly. A channel quality measurement section ( 140 ) measures channel quality of the radio channel from an AMD-PDU received. According to the ACK/NACK generation situation and the channel quality measured, a WSN determination section ( 160 ) determines a WSN appropriate for the channel condition and outputs the WSN to a status PDU generation section ( 170 ). More specifically, the WSN determination section ( 160 ) determines the WSN, for example, according to the ratio of ACK/NACKs generated in the near past and SIR measurement values. When the status PDU generation section ( 170 ) generates a status PDU, it sets the WSN determined by the WSN determination section ( 160 ) in the WSN field.
