1. A transceiver 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 the transceiver that moves, the transceiver comprising:
a plurality of antennas that performs communication with the one or more first communication apparatuses 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 a known reference signal transmitted from the one or more first communication apparatuses; and
an antenna controllor configured to control the plurality of antennas using 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,
wherein
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,
further comprising:
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 first communication apparatuses is located, and wherein the time schedule creator creates the schedule on a basis of a movement route of the transceiver.
