Title:
RADIO TRANSMISSION DEVICE AND METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2002261866
Kind Code:
A
Abstract:

To provide a radio transmission device and a radio transmission method capable of performing simple transmission control.

As a flow control method for information transmission, an information sender device is allowed to transmit packets within window size 45 in unreceived packets in acknowledgement(ACK) information from an information receiver device instead being notified of buffer null information by the receiver device, and suppresses the transmission of the packets exceeding the window size 45. In this way, the sender transmits the packets within the window size 45 to the receiver unconditionally even when the receiver does not confirm whether or not ACK information is received. Further, a transmission pointer 43 and an ACK receiving pointer 42 are provided to perform control using the transmission window size 45 by which transmission is possible even when the acknowledgement(ACK) information is not received.
