Transceiver, wireless communication system and wireless communication method

A wireless communication system including one or more first communication apparatuses serving as reference at a time of forming a communication area, a second communication apparatus located near the one or more first communication apparatuses, and a transceiver that moves, wherein

• the one or more first communication apparatuses
• transmit a reference signal including at least identification information to the transceiver at a communicable timing with the transceiver,
• the transceiver includes
• a plurality of antennas that performs communication with the one or more first communication apparatuses serving as the reference at a time of forming the communication area and the second communication apparatus located near the one or more first communication apparatuses,
• a channel estimator configured to perform channel estimation for each of the one or more first communication apparatuses based on the reference signal transmitted from the one or more first communication apparatuses, and
• an antenna controllor configured to control the plurality of antennas using an estimation value obtained by the channel estimation to form a beam having directivity in a direction in which the one or more first communication apparatuses are located, and
• according to the control of the antenna controllor, the plurality of antennas forms a transmission beam in a communication area formed in a predetermined range including the one or more first communication apparatuses or forms a reception beam for receiving a signal transmitted from the second communication apparatus located in the communication area,
• wherein the transceiver further comprises:
• a time schedule creator configured to create a schedule indicating a timing of forming a beam having directivity in a direction in which each of the one of more first communication apparatuses is located, and wherein the time schedule creator creates the schedule on a basis of a movement route of the transceiver.

A wireless communication method in a wireless communication system including one or more first communication apparatuses serving as reference at a time of forming a communication area, a second communication apparatus located near the one or more first communication apparatuses, and a transceiver that moves, the method comprising:

• performing channel estimation for each of the one or more first communication apparatuses based on a known reference signal transmitted from one or more communication devices serving as reference at a time of forming a communication area;
• controlling a plurality of antennas using an estimation value obtained by the channel estimation to form a beam having directivity in a direction in which the one or more first communication apparatuses are located;
• and
• forming a transmission beam in a communication area formed in a predetermined range including the one or more first communication apparatuses, or forming a reception beam for receiving a signal transmitted from the second communication apparatus located in the communication area,
• creating a schedule indicating a timing of forming a beam having directivity in a direction in which each of the one or more first communication apparatuses is located, and
• creating the schedule on a basis of a movement route of the transceiver.
