Wireless communication apparatus with physical layer processing module and mac layer processing module and its communication method

A wireless communication apparatus comprising:

• a first wireless communication module which constitutes a first wireless communication system which transmits and receives first data to and from a first wireless device by a first communication method;
• a second wireless communication module which constitutes a second wireless communication system which transmits and receives second data to and from a second wireless device in each interval time-divided with determined transmission timing by a second communication method differing from the first communication method;
• an inhibit period generation module which generates inhibit periods for preventing the first wireless communication module from communicating by use of the first data, on the basis of information on the second communication method held in the second data and/or the transmission timing;
• an occupation time calculation module which calculates an occupation time required for the transmission and reception of the first data,
• wherein each of the inhibit periods is generated by the inhibit period generation module each time the transmission timing is reached;
• and
• a transmission control module which compares the period between the inhibit periods adjacent to one another with the occupation time and, according to the comparison result, instructs the first wireless communication module to stop or delay the transmission of the first data,
• the transmission control module stops or delays the transmission of the first data if the occupation time is longer than the period between the inhibit periods adjacent to one another.
