Wireless communication system, wireless communication device, and non-transitory storage medium

A wireless communication device usable as a first wireless communication device in a wireless communication system comprising at least the first wireless communication device and a second wireless communication device that periodically switch a reception channel and wirelessly communicate, the wireless communication device comprising:

• a detector configured to detect an overlap schedule period during which the first wireless communication device and the second wireless communication device use the same reception channel, based on a use schedule period of the reception channel of the first wireless communication device and a use schedule period of the reception channel of the second wireless communication device;
• a determiner configured to determine to extend or reduce the use schedule period of the reception channel of the first wireless communication device, based on the detected overlap schedule period;
• an adjuster configured to adjust the use schedule period of the reception channel of the first wireless communication device so as to be extended or reduced according to the determination;
• and
• a receiver configured to switch the reception channel at an expiration time point of the adjusted use schedule period.

A non-transitory storage medium storing a program executed by a wireless communication device usable as a first wireless communication device in a wireless communication system comprising at least the first wireless communication device and a second wireless communication device that periodically switch a reception channel and wirelessly communicate, the program causing the first wireless communication device to execute:

• detecting an overlap schedule period during which the first wireless communication device and the second wireless communication device use the same reception channel, based on a use schedule period of the reception channel of the first wireless communication device and a use schedule period of the reception channel of the second wireless communication device;
• determining to extend or reduce the use schedule period of the reception channel of the first wireless communication device, based on the detected overlap schedule period;
• adjusting the use schedule period of the reception channel of the first wireless communication device so as to be extended or reduced according to the determination;
• and
• switching the reception channel at an expiration time point of the adjusted use schedule period.
