Abstract

PURPOSE:To remove the loss time of rise time or the like in a system and to improve transmission efficiency by continuously transmitting a block to which block number is added. CONSTITUTION:When transmitting blocks I -IV11 continuously, a local station waits a response signal from a master station. When the master station receives the information blocks I , II, III without errors and detects an error in the information block III, the master station returns ACK I , ACKII, NACKIII, ACKIV 12 with the block number continuously. Receiving the ACK I , ACKII, ACKIV from the master station, the local station decides that the information blocks I , II, IV are precisely sent to the master station. Receiving the NACKIII, the local station decides that the information block III is not precisely sent to the master station and should be sent again. Therefore, the local station transmits the information block III and the succeeding information blocks V-VII13 continuously. The master station returns continuously ACKIII-VI for the information blocks III-VI receives without errors and NACKVII for the information block in which a receiving error is detected. The local station repeats said operation to the master station.

Regarding the information transmission method used between a master station and a mobile slave station in simplex radio, generally speaking, when transmitting relatively long variable length information, the information transmission rate is considered in consideration of the system. The data is divided into blocks with a bit length commensurate with the data, and transmission is controlled on a block-by-block basis. If high reliability is required against communication path errors seen in mobile communications, for example, A RQ (AutomaticR
A so-called error detection/data retransmission method called an error detection/data retransmission method is adopted. Therefore, here, for example, 10 blocks of information are transmitted from the slave station to the master station via ARQ.
A conventional example of transmission using this method will be explained. FIG. 1 is a diagram showing an example 1' of the transmission procedure.

First, the slave station sends out information block 1.1 and waits for a response from the master station. On the other hand, if the master station receives this information without error, it returns an AOK signal 2 to the slave station. When the slave station receives AOK signal 2 from the master station, it determines that the previously sent information block ■・1 has accurately reached the master station, and then sends out information block ■・3 to receive a response from the master station. Waiting for.

Based on this NAK signal 4, the slave station determines that the previously sent information block 2.3 did not accurately reach the master station, and sends out the information block 2.5 again. When the master station receives the retransmitted information block 2.5 without error, it sends out an ACK signal 6. Upon receiving this person's CK signal 6, the slave station further transmits the next information block.

The above operation is repeated until the slave station sends out up to information block X.7, and when the AOK signal 8 corresponding thereto is received from the master station, the information transmission ends.

Therefore, each time one signal is sent out, a rise time of the transmitter, receiver, etc. is required in order to stabilize the system, resulting in loss time. Furthermore, since the response signal is generally very short, the rise time of the system occupies a large proportion of the transmission time, resulting in a disadvantage of low transmission efficiency.
