CROSS REFERENCE TO RELATED APPLICATION(S)

This application is based upon and claims benefit of priority from Japanese Patent Application No. 2019-214912, filed on Nov. 28, 2019, the entire contents of which are incorporated herein by reference.

BACKGROUND

The present invention relates to a communication device.

In recent years, various kinds of technologies of measuring a distance between devices have been developed. For example, JP H11-208419A discloses a technology of measuring a distance between devices on the basis of a time period from transmission of a signal for measuring the distance between the devices to reception of a response thereto.

However, according to the technology disclosed in JP H11-208419A, a receiver of the signal for measuring the distance between the devices has to consume electric power during the time period of waiting for reception of the signal. Such a situation also happens in cases of signals other than the signal for measuring the distance between the devices.

Accordingly, the present invention is made in view of the aforementioned issues, and an object of the present invention is to provide a mechanism that makes it possible to reduce electric power to be consumed to wait for reception of signals.

SUMMARY

To solve the above described problem, according to an aspect of the present invention, there is provided a communication device comprising a control section configured to perform control in such a manner as to wait for reception of a second signal transmitted from another communication device after a first signal is transmitted to the other communication device.

To solve the above described problem, according to another aspect of the present invention, there is provided a communication device comprising a control section configured to perform control in such a manner as to transmit a second signal to another communication device after a first signal is received from the other communication device.

To solve the above described problem, according to another aspect of the present invention, there is provided a communication device configured to transmit a fifth signal to another communication device, wherein the fifth signal is a signal for instructing the other communication device to wait for reception of a second signal transmitted from the communication device after the fifth signal, and the fifth signal and the second signal are transmitted and received in conformity with different wireless communication standards.

To solve the above described problem, according to another aspect of the present invention, there is provided a communication device comprising a control section configured to perform control in such a manner as to wait for reception of a second signal transmitted from another communication device after a fifth signal is received from the other communication device, wherein the fifth signal and the second signal are transmitted and received in conformity with different wireless communication standards.

As described above, according to the present invention, it is possible to provide the mechanism that makes it possible to reduce electric power to be consumed to wait for reception of signals.
