Abstract

A transmission device (11) comprises a transmitter (13) for transmitting various signals to a reception device (12), a receiver (15) for receiving a response signal emitted from the reception device (12) in response to the transmission of the various signals from this transmitter (13) to the reception device (12), a transmission/reception controller (14) for performing control of the receiver (15) and the transmitter (13), and a reception specifier (16) for specifying the reception timing of the intermittent reception of the reception device (12) when a response signal from the reception device (12) has been received. The transmission/reception controller (14) decides the timing at which the transmission of the various signals will begin, and how long the transmission will last, on the basis of the reception timing specified by the reception specifier (16).

Claims

1-7. -7. (canceled)

8. A transmission device for performing communication with a reception device that performs intermittent reception, comprising:

a transmitter configured to transmit various signals to the reception device;

a receiver configured to receive a response signal emitted from the reception device in response to a transmission of the various signals from this transmitter to the reception device;

a reception specifier configured to specify a reception timing of an intermittent reception of the reception device when a response signal from the reception device has been received; and

a transmission/reception controller configured to perform control of the receiver and the transmitter, and decide a timing at which the transmission of the various signals will begin, and how long the transmission will last, on the basis of the reception timing specified by the reception specifier.

9. The transmission device according to claim 8, further comprising:

a transmission device information memory configured to store a data transmission waiting time from when the response signal is received until a data transmission begins; and

a reception device information memory configured to store an intermittent reception interval of the reception device, a response signal transmission waiting time from when the various signals are received until the response signal is transmitted, and an intermittent reception resumption waiting time from the end of communication until intermittent reception is resumed,

wherein the reception specifier specifies the reception timing of an intermittent reception of the reception device on the basis of the timing at which the response signals are received, the data transmission waiting time, and the intermittent reception resumption waiting time.

10. The transmission device according to claim 8,

further comprising a reception device information memory configured to store an intermittent reception interval of the reception device and a response signal transmission waiting time from when the various signals are received until the response signal is transmitted,

wherein the reception specifier specifies the reception timing of an intermittent reception of the reception device on the basis of the reception timing of the response signal.

11. The transmission device according to claim 8, wherein
