COMMUNICATION DEVICE, TRANSMISSION METHOD AND RECEPTION METHOD

摘要

FIELD: information technology. ^ SUBSTANCE: communication system has a communication device which processes reception of data transmitted at a time instant in a predefined interval. The communication device has a transmitting unit configured to transmit a signal indicating that data have been successfully received when data transmitted in the M-th time instant according to a predefined interval have been successfully received, and a control unit configured to perform control in order to provide a period in which at least another reception processing is performed, or the reception process is not performed until the next (M+1)-th time instant according to the predefined interval after transmitting a signal. ^ EFFECT: reduced loss in reception or transmission operations when retransmission takes place outside a predefined interval due to retransmission control. ^ 2 cl, 12 dwg
