Patent ID: 8144681

Claim:
A wireless communication method for a wireless communication system provided with a first wireless communication apparatus having a first radio unit and a first central processing unit connected to the first radio unit, and a second radio unit and a second central processing unit connected to the second radio unit, a second wireless communication apparatus communicating wirelessly with the first wireless communication apparatus, comprising a notification information reception step in which the first radio unit and the second radio unit in the first wireless communication apparatus receive notification information transmitted by a notification channel from the second wireless communication apparatus; a transmission timing calculation step in which the first central processing unit calculates first transmission timing based on reception timing of the notification information received by the first radio unit, and the second central processing unit calculates second transmission timing based on reception timing of the notification information received by the second radio unit; an initial communication step in which the first wireless communication apparatus performs, by the first radio unit and based on the first transmission timing, initial communication with the second wireless communication apparatus by a control channel; a communication-time information acquisition step in which the first central processing unit acquires information of communication time at the initial communication step from the second wireless communication apparatus; a first correction step in which the first transmission timing is corrected based on acquired information of the communication time; a transmission step in which the acquired information of the communication time is transmitted to the second central processing unit. a second correction step in which the second central processing unit corrects the second transmission timing based on the information of the communication time acquired from the first central processing unit; and an information transmission step in which the first wireless communication apparatus transmits information from the first radio unit and the second radio unit at the corrected first transmission timing and second transmission timing respectively.
