PROBLEM TO BE SOLVED: To provide a wireless communication system which is improved in transfer efficiency in time division and avoids a collision of signals by controlling transmission timing by a wireless LAN access point. SOLUTION: The wireless communication system is constituted of: a terminal which is mounted with a double communication mode of a wireless LAN/Bluetooth (R) communication system, and performs the time division of data A to perform wireless communication; and a wireless LAN access point (AP). At this time, the terminal transmits three pieces of time information, a wireless LAN occupation time T1, a Bluetooth (R) occupation time T2, and a time T3 passed from the start of a wireless LAN occupation time to the AP as the data A as shown in the above figure. Then, the AP calculates communicable time zones to the terminal based on three pieces of time information (T1, T2, T3). Thus, the AP avoids the Bluetooth (R) communication time (T11, T13, T15) of the terminal to transmit data B to the terminal in the communicable time (T12, T14) as shown in the following figure.
