Abstract: In a wireless communication system in which a plurality of base stations each forming a directional beam in one direction are disposed along a predetermined path, each base station estimates a distance from installed in a mobile body moving along the path if the TE enters a cell area of the corresponding base station; and controls the transmission power using a distance from the estimated TE so that a difference between received signal strength of the corresponding base station and the received signal strength of neighboring base stations measured by the TE in a cell boundary area between the base stations does not exceed a predetermined threshold value.

Abstract: A method and an apparatus for acquiring channel information in a polarization division duplex system. An uplink signal transmitted from a terminal is received, the uplink signal indicating that a null subcarrier is disposed in a first subcarrier overlapped with a second subcarrier including a downlink pilot signal, and a self-interference channel is estimated by using a signal received from the null subcarrier. A signal corresponding to the null subcarrier from the uplink signal is removed, and channel information is acquired by estimating the uplink channel based on estimation results of the self-interference channel and a pilot signal included in the uplink signal from which the null subcarrier is removed.
