Information processing device, communication system, and information processing method

An information processing method, comprising:

• receiving, by wireless communication circuitry of an information processing device, a wireless signal having backward compatibility and including address fields;
• upon detecting a frame check sequence (FCS) up to a media access control (MAC) header in the wireless signal, in a case where there is no error in data of the MAC header in the wireless signal, stopping, by the wireless communication circuitry, reception of the wireless signal based on first information of the address fields, which are included in the MAC header of the wireless signal;
• and
• changing, by processing circuitry, a carrier sense level for transmission in a case where second information of the address fields of the wireless signal of which the reception is stopped is not for a second wireless communication device to which the first wireless communication device is connected.

A non-transitory computer readable medium including executable instructions, which when executed by an information processing device cause the information processing device to execute an information processing method, the method comprising:

• receiving, by wireless communication circuitry of the information processing device, a wireless signal having backward compatibility and including address fields;
• upon detecting a frame check sequence (FCS) up to a media access control (MAC) header in the wireless signal, in a case where there is no error in data of the MAC header in the wireless signal, stopping, by the wireless communication circuitry, reception of the wireless signal based on first information of the address fields, which are included in the MAC header of the wireless signal;
• and
• changing, by processing circuitry of the information processing device a carrier sense level for transmission in a case where second information of the address fields of the wireless signal of which the reception is stopped is not for a second wireless communication device to which the first wireless communication device is connected.
