Abstract
A macrocell base station includes a storage to store information of a plurality of virtual areas obtained by dividing a macrocell and information of small cells associated with the plurality of virtual areas, and a controller to perform a process of specifying the virtual area where the terminal is located, the specifying using a distance between the macrocell base station and the terminal residing in the macrocell, and a process of generating cell search information for the small cell that is to be transmitted to the terminal, the generating using the small cell information associated with the information of the specified virtual area.
Claims8
A macrocell base station to form a macrocell, the macrocell base station comprising:
- a storage configured to store information of a plurality of virtual areas obtained by dividing the macrocell and information of small cells associated with the plurality of virtual areas;
- and
- a controller configured to perform a process of specifying the virtual area where the terminal is located, the specifying using a distance between the macrocell base station and the terminal residing in the macrocell, and a process of generating cell search information for the small cell that is to be transmitted to the terminal, the generating using the small cell information associated with the information of the specified virtual area.
A terminal residing in a macrocell formed by a macrocell base station, comprising:
- a controller configured to perform a process of receiving, from the macrocell base station, cell search information of the small cell related to a virtual area of a plurality of virtual areas obtained by dividing the macrocell, the virtual area that the terminal is located being specified based on a distance between the macrocell base station and the terminal, and a process of controlling the cell search for the small cell, based on the cell search information.
A small cell search control method of a macrocell base station to form a macrocell, the method comprising:
- storing information of a plurality of virtual areas obtained by dividing the macrocell and information of small cells associated with the plurality of virtual areas;
- specifying, by a processor, the virtual area in which the terminal is located, the specifying using a distance between the macrocell base station and the terminal residing in the macrocell;
- and
- generating, by a processor, cell search information for the small cell that is to be transmitted to the terminal, the generating using the small cell information associated with the information of the specified virtual area.
A small cell search control method of a terminal residing in a macrocell formed by a macrocell base station, the method comprising:
- receiving cell search information of a small cell located in a virtual area in which the terminal is located, the virtual area being one of a plurality of virtual areas obtained by dividing the macrocell, the virtual area being obtained by using a distance between the macrocell base station and the terminal;
- and
- controlling, by a processor, the cell search for the small cell, based on the cell search information.
