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.
Claims15
A method for controlling transmission power of each base station 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, the method comprising:
- estimating 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
- controlling 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.
An apparatus for controlling transmission power of a base station disposed at a predetermined distance along a path in a wireless communication system, the apparatus comprising:
- an antenna forming a directional beam in one direction toward the path;
- and
- a processor estimating a distance from terminal equipment (TE) installed in a mobile body moving along the path if the TE enters an area of the antenna, and controlling 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 and the neighboring base stations does not exceed a predetermined threshold value.
