Abstract
A transceiver includes: a plurality of antennas that performs communication with one or more first communication apparatuses serving as reference at the time of forming a communication area and a second communication apparatus located near the one or more first communication apparatuses; a channel estimation unit 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 control unit 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. According to the control of the antenna control unit, 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.
