Abstract

PURPOSE:To improve the transmission efficiency data by making the retransmission of a block from a system-side minimum and to reduce the over again transmission efficiency of data by adding an unreceivable packet number in a block reception failure number. CONSTITUTION:When a terminal (a) has normally received an m-th block, it transmits a block signal (block ACK) to a system and receives an (m+1)-th block from the system-side. When a first packet cannot normally be received, the terminal (a) transmits a block reception defective signal (block NAK), and adds the unreceivable packet number (i) into the signal. When the system-side receives the content that an i-th packet in the block NAK signal cannot be received, it retransmits only the i-th packet D(i) of the (m+1)-th block to the terminal (a). When the system-side receives the block reception normal signal from the terminal (a), the transmission of the (m+1)-th block terminates. Thus, the transmission efficiency of data is improved by setting the retransmission of the system-side as the minimum, and the over again transmission efficiency of data can be reduced.

When the data is received normally, a block reception good signal (PRO, RIACK) is sent, and when there is an error in the received data, a block reception failure signal (block NAK) is sent.

In the conventional technology described above, when the system side receives a corresponding block reception failure signal (block NAK) from the terminal, it sends all the corresponding blocks to the terminal again.

For this reason, in reality, the terminal does not retransmit even what it has received accurately, leading to a decrease in data transmission efficiency and an increase in the retransmission rate due to an increase in the amount of data retransmission, which is a serious drawback. .

This will be explained with reference to FIG. When the terminal α normally receives the m-th block, it transmits a block reception good signal (block ACK) to the system. Next, the terminal α receives the (m+1)th block from the system side, but if the i-a4th packet cannot be received normally, the terminal α transmits a block reception failure signal (pro-NAK). . Then, the mother packet number (i) that could not be received is assigned to this block reception failure signal.
