Patent ID: 8238835

Claim:
A wireless communication system including a wireless terminal station that performs a communication using directional beams formed in a plurality of directions, wherein the wireless terminal station includes at least a first wireless terminal station that transmits beam transmission direction identification information in all directions, in which the information can be transmitted, over a period designated from a wireless base station covering the first wireless terminal station at a beam switching execution interval notified to the wireless base station in advance, and a second wireless terminal station that performs, when the second wireless terminal station is covered by the wireless base station together with the first wireless terminal station, a reception operation for the transmission direction identification information, which is transmitted from the first wireless terminal station, in all reception directions over a period designated from the wireless base station at an antenna switching execution interval designated from the wireless base station, combines reception direction identification information and the transmission direction identification information at the reception of the transmission direction identification information to specify the combined reception direction identification information and the transmission direction identification information as directivity direction combination information, and transmits the directivity direction combination information to the first wireless terminal station, and the wireless communication system further comprises a wireless base station that determines the period and the antenna switching execution interval based on a number of directivity directions of directional beams notified from the first and second wireless terminal stations and the beam switching execution interval, and the first wireless terminal station and the second wireless terminal station form the directional beams in directions indicated by the directivity direction combination information to thereby perform a direct communication.
