Communication device that performs performing wireless communication with another communication device, control method thereof, and storage medium

A control method of a communication device capable of executing wireless communication with another communication device, the control method comprising:

• setting a frequency band to be used for communication in a second mode in which wireless communication with another communication device is performed without using a relay device according to a communication scheme conforming to a predetermined communication standard;
• performing control to perform wireless communication in the second mode using the set frequency band, when the wireless communication is performed in the second mode in a case where connection of wireless communication in a first mode, in which wireless communication with another communication device is performed via the relay device according to the communication scheme conforming to the predetermined communication standard, using a frequency band at least partially overlapping the set frequency band is not made;
• and
• performing connection of wireless communication in the first mode, using a frequency band at least partially overlapping a first frequency band, wherein the set frequency band is the first frequency band,
• wherein control is performed such that in a case where the set frequency band is the first frequency band, and connection of wireless communication in the first mode is performed using a frequency band at least partially overlapping the first frequency band, connection of wireless communication in the second mode using the first frequency band is not performed.

A non-transitory computer-readable storage medium storing one or more programs configured to cause one or more computers to function as units in a communication device, the units comprising:

• a first communication unit configured to perform communication in a first mode in which wireless communication with another communication device is performed via a relay device according to a communication scheme conforming to a predetermined communication standard;
• a second communication unit configured to perform communication in a second mode in which wireless communication with another communication device is performed without using the relay device according to the communication scheme conforming to the predetermined communication standard;
• a setting unit configured to set a frequency band to be used for communication in the second mode;
• and
• a control unit configured to perform control such that:
• when wireless communication is performed in the second mode in a case where connection of wireless communication in the first mode using a frequency band at least partially overlapping the frequency band set by the setting unit is not made, the wireless communication in the second mode is performed using the frequency band set by the setting unit;
• and
• in a case where a first frequency band is set by the setting unit and connection of wireless communication in the first mode is made using a frequency band at least partially overlapping the first frequency band, connection of the wireless communication in the second mode using the first frequency band is not performed.
