Abstract
Disclosed is a cell control device and method that can improve data processing capacity and speed of each cell by removing inter-cell interference due to transmission of system information blocks (SIB), which are transmitted in a broadcast manner from cells by reducing the number of times of transmission of the system information blocks or removing the system information blocks in a wireless environment including a plurality of small cells in a macrocell.
Claims10
A cell control device comprising:
- a determiner configured to determine the number of terminal connected to a macrocell in a wireless environment including a plurality of small cells in the macrocell;
- and
- a controller configured to control each of the plurality of small cells to block transmission of system information block in a broadcast manner and the macrocell to perform transmission of system information block in a broadcast manner when the number of terminal is less than a threshold value, and to control the each of the plurality of small cells and the macrocell to perform transmission of system information block in a broadcast manner when the number of terminal is the threshold value or more.
A cell control method comprising:
- determining the number of terminal connected to a macrocell in a wireless environment including a plurality of small cells in the macrocell;
- and
- controlling each of the plurality of small cells to block transmission of system information block in a broadcast manner and the macrocell to perform transmission of system information block in a broadcast manner when the number of terminal is less than a threshold value, and the each of the plurality of small cells and the macrocell to perform transmission of system information block in a broadcast manner when the number of terminal is the threshold value or more.
