Title:
CELL QUALITY EVALUATION DEVICE, AND CELL QUALITY EVALUATION METHOD
Document Type and Number:
Japanese Patent JP2015082680
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To evaluate a communication quality at each cell without simulation at a complicated system level, in a wireless communication system in which a frequency band is allocated to a terminal by frequency scheduling.SOLUTION: A cell quality evaluation device comprises: means for arranging terminals at random in a target region where a coordinate of an antenna of each cell is defined; calculation means; and storage means. The calculation means performs calculation processing of accommodating each arranged terminal in a cell chosen on the basis of a preliminarily-defined reference, selecting one terminal at random in each cell, calculating a desired wave power, an interference wave power, and SINR respectively for both uplink and downlink for each selected terminal, and storing the calculated desired wave power, interference wave power, and SINR in the storage means. The arrangement of the respective terminals by the terminal arrangement means and calculation processing by the calculation means are repeatedly performed to acquire distributions of desired wave power, interference wave power, and SINR at the communication in each cell, respectively for both uplink and downlink.
