Title:
PACKET COMMUNICATION DEVICE AND PACKET COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2005/011209
Kind Code:
A1
Abstract:
There are provided a packet communication device and a packet communication method capable of suppressing lowering of the throughput of the whole system and preventing generation of communication reset/disconnection. An ACK generation section (130) generates ACK/NACK indicating whether the data transmitted via a radio line has been normally demodulated. A line quality measurement section (140) measures the line quality of the radio line from an AMD-PDU received. According to the generation condition of the ACK/NACK and the line quality measured, a WSN decision section (160) decides a WSN appropriate for the line state and outputs it to a status PDU generation section (170). More specifically, the WSN decision section (160) decides the WSN, for example, according to the ratio of ACK/NACK generated recently and a SIR measurement value. When the status PDU generation section (170) generates a status PDU, it sets the WSN decided by the WSN decision section (160) in the WSN field.
